Patent ID: 8052952

Claim:
A composite comprising a carbon nanotube structure and a polymer, wherein: the carbon nanotube structure has a network structure constructed by curing a solution containing multiple carbon nanotubes to which multiple functional groups are bonded, forming a cross-linked site through chemical bonding of the multiple functional groups bonded to the carbon nanotubes; the polymer comprises one polymer selected from the group consisting of polyethylene, polypropylene, polyvinyl chloride, polyamide, polyimide, and an epoxy resin and is present in the network structure in the gaps created by crosslinking the multiple functional groups bonded to the carbon nanotubes; and the cross-linked site has a chemical structure selected from the group consisting of —COO(CH 2 ) 2 OCO—, —COOCH 2 CHOHCH 2 OCO—, —COOCH 2 CH(OCO—)CH 2 OH, and —COOCH 2 CH(OCO—)CH 2 OCO—.
