Abstract

Blends of polyurethane (PU) and aniline-containing poly(urethane-urea) (PUUA) copolymer doped with different protonic acids, including camphorsulfonic acid (CSA) and dodecylbenzenesulfonic acid (DBSA), were prepared and studied. According to those DMA and DSC results, the blends show a partial compatibility and purification effect between the composed components of the blends. The blends using CSA as a dopant resulted in better heat resistant and tensile strength but poorer electronic conductivity than that of DBSA doped one.
