Carbodeon (Helsinki, Finland) reported on Nov. 13 that it has been granted a US patent for its technology that enables detonation-synthesised diamond particles (nanodiamonds) to be combined with polymers for use in fields such as personal electronics, LED lighting, automotive parts and machine tools.

Nanodiamond-impregnated polymers can deliver heat-conducting benefits for products including LED lighting, mobile devices including cellphones, and Internet-of-Things (IoT)-enabled devices of any type. The hard-wearing properties of nanodiamond mean they can also be used in the aerospace and automotive sectors to enable longer product life in hard-wear environments.

The patent was filed after Carbodeon’s own developments during 2012-2013 where they discovered the thermal conductivity of thermoplastics can be significantly enhanced by adding nanodiamonds, usually in relatively small quantities. 

Vesa Myllymaki, Carbodeon CTO, says, “The granting of this patent represents a key part of our nanodiamond composite material porholio. The combined coverage of our filed and granted patents will secure our position and that of our customers in several nanodiamond applications including polymers for thermal management applications, wear and corrosion-resistant nanodiamond metal finishing, and wear resistant/low friction nanodiamond fluoropolymer coatings.”

Gavin Farmer, Carbodeon business development manager, says, “This latest achievement means that we will now accelerate our marketing of Carbodeon uDiamond NanoDiamond materials for use as thermal fillers in thermoplasXcs.
