Abstract:In this study, a polyimide gel material with a high spatial network structure was synthesized. The pyrolysis process increased the material’s porous structure and specific surface area to improve the specific capacitance. The effects of pyrolysis temperature on morphology, structure, thermal, mechanical, and electrochemical properties were studied. The gel material is in the frozen state of the molecular chain from the frozen state to the moving state before 400°C. At the same time, pore structure formation wi… Show more
