European Company Granted US Patent for Nanodiamond-Containing Polymers

UV+EB Technology

Carbodeon, Helsinki, Finland, has been granted a US patent for its technology that enables detonation-synthesized diamond particles (nanodiamonds) to be combined with polymers for use in such fields as personal electronics, LED lighting, automotive and machine tools.

Diamonds are the hardest natural mineral and also one of the most thermally conductive materials known, so when nanodiamonds are mixed with thermoplastic polymers in controlled amounts, they can enable plastic materials to conduct heat at pre-determined rates and/or to be highly wear-resistant. Nanodiamond-impregnated polymers can deliver heat-conducting benefits for products that include LED lighting, mobile devices including cellphones, and Internet-of-Things (IoT) enabled devices of any type.

The hard-wearing properties mean they also can be used in the aerospace and automotive sectors to enable longer product life in hard-wear environments. Since filing the patent, Carbodeon continued its own research, as well as developing the range of commercial applications of the technology. Carbodeon has been granted US patent no. 9085723 on its developed nanodiamond containing thermoplastic thermal composites. The patent was filed after Carbodeon’s own developments during 2012-2013 where it discovered the thermal conductivity of thermoplastics can be enhanced by adding nanodiamonds, usually in relatively small quantities.
