Abstract

Provided is a method for preparing a carbon nanotube/polymer composite material, including: coating a nano-silicon oxide film on the surface of a porous polymer by vacuum coating; depositing a metal catalyst nano-film on the nano-silicon oxide film by vacuum sputtering; growing a carbon nanotube array in situ on the surface of the porous polymer by plasma enhanced chemical vapor deposition to obtain a carbon nanotube/polymer porous material; and impregnating the carbon nanotube/polymer porous material with a polymer and curing to obtain the carbon nanotube/polymer composite material. By using a heat-resistant polymer having a high heat-resistant temperature and a PECVD technique, a carbon nanotube array directly grows in situ on the surface of a polymer at a low temperature, which thereby overcomes the defects of the composites previously prepared, in which carbon nanotubes are difficult to be homogeneously dispersed and the interfacial bonding force in the composites is weak.
