  • Conductive sheet, method for manufacturing the same, carbon composite paste, carbon composite filler, conductive resin material and conductive rubber material
    Patent number: 11043314
    Abstract: A conductive sheet capable of improving conductivity by suppressing reaggregation of carbon nanotubes, and a manufacturing method thereof are provided. Also, carbon composite paste and carbon composite filler are provided. The conductive sheet is characterized in that carbon nanotubes and carbon black as conductive materials are dispersed in a resin material. Carbon composite filler, which is composed of the carbon nanotubes in an amount of 10-30 wt. % and the carbon black in an amount of 90-70 wt. %, is dispersed uniformly in the resin material. The conductive sheet is composed of the carbon composite filler in an amount of 10-50 wt. % and the resin material in an amount of 90-50 wt. %, whose surface resistance value is 1-10 ?/sq.
