Problems solved by technology

[0014] Ordinary carbon nanomaterials have no functional groups on the surface, so it is difficult to compound with PET, which hinders the development of modified PET to prepare high-performance materials.
[0015] At present, a main way to explore the application of graphene in fiber is to chemically modify graphene and then complete material compounding. For example, CN103044865A discloses a preparation method of amino graphene modified PET material, which is to use amino graphene Composite preparation of PET composite materials; CN103966844A discloses a preparation method of graphene conductive composite fiber, which is to use graphene oxide to carry out chemical modification of the fiber surface and then chemical reduction to obtain graphene modified fiber; these methods all need graphene Modification treatment, on the one hand, the inherent excellent characteristics of graphene are greatly deteriorated, on the other hand, the cost of industrial production is too high, and the pressure of environmental protection production is high. At the same time, it is difficult to avoid the problems of simplification of product functions and low performance-to-cost ratio.
