Description

technical field [0001] The invention relates to the field of plastics, in particular, the invention relates to a conductive polypropylene composite material. Background technique [0002] There are numerous studies on conductive composites, but there are still many problems that have not been well resolved. For example, while adding a conductive medium to increase the conductivity, the mechanical properties decrease. Therefore, the development of conductive composite materials mainly focuses on reducing the resistivity and improving the overall performance of the material. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a conductive polypropylene composite material. The conductive polypropylene composite material of the invention not only has lower resistivity, but also has excellent comprehensive properties. [0004] The technical solution adopted by the present invention to solve the above technical problems ...
