Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a preparation method of conductive polymer materials. Background technique [0002] Composite conductive polymers are composed of polymer materials as the matrix and a certain amount of conductive substances (such as carbon black, graphite, carbon fiber, metal powder, metal fiber, metal oxide, etc.). Composite conductive polymer material is a functional polymer material composed of polymer materials and conductive substances through dispersion compounding, lamination compounding, and surface conductive film formation. The materials made by lamination and forming surface conductive film are easy to cause a lot of inconvenience after use, so the application field is also limited. Dispersion compounding is to add a large amount of conductive fillers, such as carbon black, carbon fiber, metal powder, etc., to high polymers, and then process them into composite ...

AI Technical Summary

Problems solved by technology

However, the volume resistivity required by highly conductive polymer materials is extremely low, and more conductive channels are required, so a large amount of carbon black must be added, which will easily lead to poor dispersion of carbon black and poorer compatibility with resins, which greatly affects the performance of the material. Flexibility, Physico-Mechanical Properties and Processability

[0003] At present, there are many kinds of composite high-conductive polymer materials, but there are contradictions between their electrical conductivity, processing performance and mechanical properties. Therefore, a better conductive polymer material is needed to improve the shortcomings of the existing technology.
