Description

technical field [0001] The invention belongs to the field of fiber material and plastic processing, and in particular relates to a preparation method of a functional polymer material. Background technique [0002] At present, there are mainly two methods for preparing functional materials: blending modification and surface chemical grafting modification. One is the blending modification method, which directly molds functional substances and polymer solutions or melts. The prepared functional material, whose functional components are completely embedded in the polymer material, not only cannot exert its functional effect, but also consumes a large amount of functional substances, which greatly increases the cost, and even causes difficulty in molding due to the mixing of functional components; The second is the surface grafting modification method, which generates free radicals on the surface through irradiation and other methods, and then grafts functional substance monomers...
