A series of polysulfonamide (PSA)/TiO2 (modifier) nano-composite films were successfully prepared by in-situ polymerization at a low temperature based on 4, 4-diaminodiphenylsulfone and terephthaloyl chloride in the common solvent N, N-dimethylacetamide (DMAc). It was shown that the nano particles were well dispersed in the polymer substrate. Meanwhile, PSA/TiO2/modifier composites exhibited good UV-resistant properties and mechanical properties. In addition, the composites' heat stability improved. These prepared composites are promising in preparing spinning solution and might have potential application in heat-resistant fiber.
