Description

technical field [0001] The invention belongs to the technical field of polymer material modification, and in particular relates to a conductive polymer material and a preparation method thereof. Background technique [0002] Conductive polymer materials have a good positive temperature coefficient effect (PTC effect), the resistance of the material will increase with the increase of temperature, and are usually used to replace metals to make electric heating components. Carbon black, especially nano-conductive carbon black, is usually added to the substrate to prepare conductive polymer materials due to its small particle size and large specific surface area. However, high-conductivity molecular materials require extremely low volume resistivity and require more Therefore, a large amount of carbon black needs to be added, which will easily lead to poor dispersion of carbon black and poorer compatibility with polymer materials, which greatly affects the flexibility, physical ...
