Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a hybrid polymer material which can reduce an amount of added conductive filler materials such as metal fibers and improves shielding properties and conductivity by improving interconnection of fillers.

SOLUTION: A hybrid polymer material 10 contains 0.01% to 1% by weight of carbon nanoparticles 12, 1% to 10% by weight of a conductive polymeric material 14, 1% to 20% of electrically conductive fibers 16 having a metallic surface, and 69% or more by weight of a nonconductive polymer based material 18. Preferably, the carbon nanoparticles are selected from the group consisting of carbon nanotubes, graphite nanoparticles, graphene nanoparticles, and fullerene nanoparticles. Preferably, the conductive polymeric material is selected from the group consisting of substantially conductive polymers, radical polymers and electroactive polymers. The electrically conductive fibers are selected from the group consisting of stainless steel fibers, metal plated carbon fibers and metal nanowires.
