Graphene-modified flexible polyester

The invention discloses graphene-modified flexible polyester. Graphene and polyester are modified and thus can be better combined together. The graphene is treated at first, oxidation treatment is conducted on the graphene and oxidized graphene containing hydrophilic groups like carboxyls and alkyls is obtained. Compared with the graphene, the dispersibility and adsorbability are better; and meanwhile, ethanediamine is matched to conduct amination modification on the polyester, and therefore the number of polar groups on the surface of the novel polyester is increased, the adsorption capacityto the groups like carboxyls, alkyls and epoxy groups can be improved and the high-conductivity flexible polyester is obtained. On one hand, the conditions of yarn breakage and blockage happening in the spinning process of existing polyester are avoided; and on the other hand, conductivity of the whole polyester is enhanced, and thus a foundation is provided for application and popularization of intelligent equipment. 本发明
