Patent granted to electrically conductive polymer, ElectroPhen

24-Mar-10

A materials patent has been granted for an electrically conductive polymer, ElectroPhen to cleantech materials startup Bac2. In its raw state, ElectroPhen is one billion times more conductive than other polymers and its characteristics can be tailored to each application through the addition of graphite, metal powders, plasticisers and reinforcers. This makes it suitable for fuel cells and other energy storage devices, for RF screening and static electricity protection, and for the manufacture of heating elements and heat sinks. Bac2 has also evolved a way to delay the polymerization process using a latent acid catalyst known as CSR10. This permits the pre-polymeric mixture to be transported and stored for several months before polymerization, adding flexibility to the manufacturing process and reducing costs. The patent covers Germany, France, Spain, Italy and the UK. Patent applications for the material are awaiting grant in Japan, Canada, the USA, South Korea, India and China.
