Vorbeck has applied for a patent for composites in which graphene is made to stick better to a substrate by mixing it with polymers and polyalkyleneimines. The compound has potential use in many industries, with special dedication to printed electronics.
United States Patent Application number 20120277360 was filed 28 October 2011 and published yesterday. If approved, the patent will prevent other companies from using this method to make advanced graphene composites. The method involves mixing of graphene or graphene oxide with any of a range of polymers, and an adhesion promoter which is available commercially. The text of the patent application even specifies that the adhesion promoter could be, for example, Lupasol from the German company BASF. The coating could possibly perform many functions, such as electrical conductivity, static dissipativity, electromagnetic interference shielding, thermal insulation, and corrosion protection.
Vorbeck is a US-based company on the forefront of applied graphene research, and the first to market graphene-based printed inks in an online store. Vorbeck is not on the stock market, but is probably looking for venture capital and industrial partnerships. BASF is also a strong player in the graphene field, and can be invested in on the Frankfurt stock exchange.
