Highly Conductive and Transparent Graphene Filled Acrylic Navy SBIR FY2010.2 Sol No.: Navy SBIR FY2010.2 Topic No.: N102-120 Topic Title: Highly Conductive and Transparent Graphene Filled Acrylic Proposal No.: N102-120-1263 Firm: Graphene Devices Ltd. 138 CHAPEL WOODS WILLIAMSVILLE, New York 14221-1868 Contact: Robert Anstey Phone: (716) 560-1507 Abstract: Graphene nanoparticles (platelets) exhibit extremely high conductivity and transparency, excellent mechanical properties, and facile processability that can be supplied at much lower cost than other carbon forms like nanotubes. Graphene also features tailored chemical functionality, which allows uniform dispersion of graphene platelets within a host polymer like acrylic. We will formulate Graphene-filled Acrylic (GFA) by developing graphene platelets in suitable liquid dispersions which are then used directly to produce PMMA acrylic plate. This provides a percolative or conductive network of graphene particles within the acrylic matrix at low graphene loadings, which is important for good optical properties. GDL and our program Team members each provide the necessary expertise to perform this work. This includes several leading graphene researchers and one of the largest suppliers of cast and cast/stretched acrylic to the requirements of MIL-PRF-8184 and MIL-PRF-25690 and a leading supplier of aircraft transparency material for many years. GFA samples will be produced and electrical, optical and mechanical tests performed to assess performance against established material requirements. Benefits: Graphene-filled Acrylic (GFA) and other transparent conductive polymers are ideally suited for a number of mass market applications to replace polymers coated with transparent conductive films such as ITO. There are a number of well established and large markets such as photovoltaic (solar cells), flat panel displays and electrostatic discharge/antistatic coated windows used in electronic clean rooms that are very attractive commercialization targets because they are substantial, near term and commercial (i.e. feature much shorter time-to-market than some military applications). GDL is already supplying graphene based materials and in discussions with large industrial firms to capitalize on these applications. Technology IP is protected by patent applications, and the company has secured equity partners and obtained research contracts to develop and commercialize these materials. Return
