It was believed that graphene is a wonder material, capable of changing the world like plastics.
However, we have not experienced a graphene industrial revolution yet. Slow advances in its R&D make graphene’s commercial future much less certain. The main reason behind this is cost. Despite superior properties of graphene, the cost to benefit ratio of applying graphene to commercial products is not clear. Also, the obstacle to be overcome is reliable and consistent production of high quality graphene. Here, LG Electronics has made a challenge for mass production of high quality graphene.
In this talk, it is addressed that vertical R2R CVD reactors have been developed for large area and mass production. How the graphene quality has been improved and how we control the quality for mass production is presented. Our business strategy for future graphene applications is shortly mentioned.

Since the discovery of graphene and its impressive mechanic, thermal and electrical properties, major materials research efforts have been made towards harnessing these properties for the development of polymer composites with unprecedented performance. While this research has shown that some of the bolder expectations for their properties will probably not be achievable for reasons from basic physics, substantial progress has been made in the production of composites with more down-to-earth property improvements.
At the same time, the production of graphene related materials (GRM) has made great progress with respect to available quantities, cost and resource efficiency that pragmatic applications of graphene as just another functional filler for polymer composites has become economically and ecologically viable.

While such properties are not necessarily “flashy”, they nevertheless may greatly help the polymer industry on the way of to a more circular and resource-efficient economy.

For lithium ion batteries, the use of silicon as active material on the negative electrode is most promising, since silicon offers exceptional high volumetric and gravimetric lithium storage capabilities as well as low charging/discharging potentials. However, this high storage capability is accompanied with high volume changes during lithium insertion/extraction, which causes a rapid decay in dimensional stability of the host material (1). The use of graphene-related materials can help to overcome these crucial problems, as graphene offers a highly conductive and mechanically stable matrix that can suppress or buffer this large volume expansion (2) (3). Consequently, graphene-related materials improve the cycling stability by retaining the native structural integrity as well as the electrode porosity.

An introduction how graphene can enhance heat dissipation in electronic devices as well as for coatings and plastic materials is given. A short overview on the processing steps to get highly flexible heat dissipation film with graphene oxide as starting precursor is discussed. Finally the latest R&D results for corrosion protection is presented.

​

The application bulk graphene materials in composites is predicted to be the largest market for graphene. Several products based on composites, mainly in sport good sector, claims that are based on graphene materials (GRMs).
GRMs are a family of materials with remarkable differences in morphology, aspect ratio, surface chemistry. An adequate selection of the GRM and processing technique is a key factor for achieves the desired properties.
In the presentation we will describe the influence of the GRM and processing technologies for the preparation of multifuctional composites with electrical and/or thermal conductivity, mechanical performance, fire retardancy, barrier properties and the potential market and actual large volume application in the polymer composites sector.

Sixonia Tech has developed a process that creates the ability to functionalize few-layer graphenes deliberately and precisely, directly during their production. Compared to other “graphene” products, our E-Graphenes show a superior combination of tailorable properties within a single material, such as large flake-size in the µm-range, low thickness in the range of typically 1-5 layers and good processability. Unlike in (r)GO, the defined functional groups can provide an improved processability, while still maintaining high electrical conductivity and reasonable sheet size.
Our scalable and eco-friendly electrochemical process opens up new possibilities and prospects for the applications of graphene, in the field of inks, composites, sensors, energy storage and energy conversion. As an example, our E-Graphenes can be functionalized to be dispersible in water without the need for surfactants, while still maintaining an intrinsic conductivity that is at least one order of magnitude higher than that of commonly used reduced graphene oxide (rGO) materials. In contrast to liquid phase exfoliated (LPE) graphene materials, the absence of surfactants can also significantly increase achievable conductivities after deposition and reduce the number of necessary downstream processing steps.

There are many companies worldwide claiming to produce “graphene materials” but showing huge disparity in their properties. Because of that, many industrial applications were hindered by quality and price of graphene. In this space, 2D Materials Pte. Ltd.

Textile is the natural interface coating the average human appr. 95% of lifetime and beyond. Ability to read and deliver electrical signals to human skin would enable constant human-machine interaction as a part of future digital world. So far, textile conductivity was realized either by incorporation of conductive threads during manufacturing or via applying a conductive paint onto its surface after manufacturing. We have developed a method for fabrication of electrically active fabric via coating the textile fibres on the nanoscale level. Upon adding 2gr/sqm of graphene, the textile becomes conductive, but preserves its original properties – softness and permeability. Such lightweight, flexible and breathable textiles can enable the future digital textile interfaces for human-machine interaction.

We also provide polycrystalline graphene wafer directly grown on silicon oxide/Si without metal layer. Furthermore, we also have the capability to fabricate h-BN thin film with thickness from one layer to multilayer up to 30 nm.

Two challenges that must be overcome to reach the potential of graphene in electronics and energy storage applications are: industrial scale quantities of high-quality graphene (properties closest to the single layer graphene) and its integration to the material composite (polymer matrix). In this presentation, PPG and Raymor will present their industrial scale production of few-layer graphene by plasma method and the different techniques to properly disperse and incorporate the powder into both water based and solvent based formulations at high loadings. This resulting graphene forms part of the novel high energy density Si-based anode material developedby NanoGraf that has the long-term potential to replace graphite-based anodes in lithium-ion batteries for a range of applications, from consumer electronics to electric vehicles.

Carbon Nanomembranes (CNMs) are a molecular thin, carbon-based 2D-sheet material complementary to graphene. Their properties (dielectric, easy chemical functionalisation, intrinsic porosity, …) are rather comparable to ultrathin polymeric films. A variety of production methods - from large area CNM-composite membranes to CMOS-compatible integration into devices - is feasible. Since CNMs are highly permeable for water, while blocking anything else, they can enable a hitherto non-attainable separation efficiency compared to existing membrane technology. CNM-composite membranes can be used in forward osmosis for cold concentration of watery solutions in the food&beverage or the fragrances&aroma industry. As reverse osmosis membranes they can filter last amounts of salt, heavy metals or small organic molecules for the provision of ultrapure water in the semiconductor or pharma industry. Other applications of CNMs are in sensor technology, energy and semiconductor manufacturing.

Wearable electronics have great potential to create better health and wellbeing for the many through the application of new technologies. However, rigid electronics still dominate the wearables sector, making them unsuitable for daily use. Truly wearable devices need to match the elasticity of the skin, show breathability, comfort and be easy to clean. What if we could develop breathable, washable, energy-harnessing and biocompatible electronics that meet these criteria. This presentation will share the latest developments of a new class of washable, breathable and skin-compatible electronic components based on natural fibres such as cotton and cellulose and 2D materials. These materials are engineered by using techniques from nanomaterials, 2D materials and organic electronics, creating new platforms for intuitve sensing. These novel textiles have applications in broad areas such as healthcare, wellbeing, IoT, lighting and sensing. Finally, I will give share my vision for the future development of 2D materials for wearable electronics.

This presentation overviews the current graphene sheet (CVD graphene) market and industry, in 2021. We'll shortly discuss CVD graphene's properties, and then look into the current applications, market and producers in 2021.

After a decade of extensive research, 2D materials and specially graphene have been expected for a long time to disrupt many fields and industries. However, there are still no truly graphene-based products in the marketplace, specially regarding CVD-graphene. We believe that a combination of factors are to blame, and that the CVD-graphene technology is actually mature enough for certain applications to enter the market and pave the way for this material to be ubiquitous.
In this session, the past and current state-of-the-art semiconductor landscapes will be discussed, with obvious emphasis towards the integration of single layer, CVD-grown graphene into semiconductor workflows. The Graphenea Foundry and its unique vertical integration manufacturing scheme will be introduced and discussed, as well the fabrication of graphene-based devices at the wafer scale; this establishes a solid platform for graphene technologies to be prototyped, developed, scaled up and commercialised.

In recent years, graphene has shown great promise as an active material for bioelectronics, including in vitro and in vivo applications. It combines optical transparency, electrical sensitivity and biocompatibility. I will present the use of monolayer graphene on polymer, and will detail the industrial applications envisaged by Grapheal in the case of wound treatment and field diagnostics.

On the industry’s path to a new generation of display performance and manufacturability, it encountered a roadblock: thin film transistor performance and manufacturability. As in the VLSI semiconductor industry before it, the display industry chose to focus on improving semiconductor material performance to break through the roadblock - moving from silicon to higher performance semiconductor materials. The plan was simple: better semiconductor + same transistor structure and materials = better TFTs. After 20 years of research and development, the semiconductor path around the roadblock has failed; it has provided about one-third of the required advances in performance, device size and manufacturability.
