Description

technical field [0001] The invention relates to an ultra-high molecular weight polyethylene composition, in particular to an ultra-high molecular weight polyethylene thermoelectric conductive material. Background technique [0002] Ultra-high molecular weight polyethylene will greatly expand its application fields due to its electrical or thermal conductivity. [0003] UHMWPE can be widely used in instruments, meters, automation equipment, gears, bearings, telephones and other fields through modification. [0004] But at present, metal materials are traditionally used as thermoelectric conduction materials in China, and plastics cannot replace metal materials due to their low electrical and thermal conductivity. Contents of the invention [0005] In order to overcome the above-mentioned defects, the present inventors conducted a lot of in-depth research, and thus completed the present invention, which provides an ultra-high molecular weight polyethylene thermoelectric con...
