Polyaniline is a good performance of a conductive polymer material, but low strength, difficult to process. In the conductive less demanding situations, and good film-forming properties. And polyimide blends having high strength and heat resistance is a good choice. Polyaniline dissolved in an aprotic polar solvent such as DMAC. You can also soluble in phenolic solvents. If the polyamide acid in an aprotic polar solvent blended, you need a high temperature of polyimide. For the requirements of high TG polyimide cyclization temperature of about 300 ℃. Polyaniline decomposition will occur more dopant will evaporate and decompose. It is possible to obtain satisfactory results with soluble polyimide blends.
