[0028] Participate figure 1 As shown, a specific embodiment of the present invention is introduced, and the preparation method of carbon nanotube network / polymer composite material includes the following steps:
[0029] S1. Provide a network structure of carbon nanotubes and polymer monomer precursor solutions. Among them, the network structure of carbon nanotubes is prepared by a floating catalytic method. The carbon source undergoes a cracking reaction in a high-temperature furnace and self-assembles into a carbon nanotube hollow network structure, with the content of carbon nanotubes reaching more than 95%. Specifically, the size of the hollow network structure of the carbon nanotubes varies according to the size of the growth furnace tube where the carbon nanotubes are located. Preferably, the size of the hollow network structure of the carbon nanotubes is about 1-5 inches. In particular, the carbon nanotube network is one or a combination of single-wall, double-wall, and mul...
