In 2020, China's leading graphene technology company, the overseas laboratory of HBDX Graphene Technology Group released a variety of graphene functional materials. The HBDX graphene research team and the British National Graphene Engineering Innovation Center (GEIC) are based on market demand and technology. Basically, through close cooperation, further iterations and technological upgrades have been achieved in functionalized transparent conductive film (Transparent Conductive Film, TCF), graphene-based self-cleaning glass (GO/Self-cleaning Glass) and graphene heating hemp products , The product parameters have reached the international leading level, providing a new business growth point for the continuous development and growth of Dongxu Optoelectronics graphene industry.
The Transparent Conductive Film solution is a transparent conductive ink made of highly disordered silver nanowires and graphene materials based on a unique process, which is coated to form a flexible transparent conductive film base layer, and the functionalized graphene independently developed by HBDX is deposited on the flexible On the base layer of the transparent conductive film, functionalized graphene and silver nanowires are stacked and assembled to form a high-performance transparent conductive film. Transparent Conductive Film can maintain a light transmittance of more than 90% under the premise that the sheet resistance is less than 50Ω/sq. At the same time, it can block more than 99% of ultraviolet rays through nanostructure optimization, which greatly improves the weather resistance of silver nanowires, and is more conductive than traditional graphene. Transparent film has the advantages of low cost, easy processing and more comprehensive functions. This technology can also be closely integrated with HBDX ultra-thin flexible glass technology to achieve new breakthroughs in technologies such as flexible display and flexible sensing.
Based on the successful landing of the Transparent Conductive Film solution, through optimizing the formula and custom assembly process, the technology further extends the graphene self-cleaning glass product. The graphene-based self-cleaning coating is sprayed on the surface of the ordinary glass substrate and sintered at a high temperature in a vacuum to form a dense Self-cleaning coating. The addition of functionalized graphene improves the hydrophilicity of the surface of the substrate after coating, reduces the accumulation of fluid on the surface of the substrate, and the contaminants deposited on the surface can be automatically degraded under natural light, making the self-cleaning glass automatically under natural conditions Keep the surface clean without frequent cleaning.
Integrate Transparent Conductive Film on the self-cleaning glass in a vacuum and dust-free environment to realize the close combination of two functional layers. The integrated glass has the functions of energized heating and light self-cleaning while maintaining high light transmittance. Functions are highly efficient and coordinated to promote each other.
