文摘

The Polyaniline (PANI)/Polybenzobisoxazole (PBO) composites doped with phosphoric acid and methanesulfonic acid are prepared by solution blending. It was found that the PANI exhibited highly homogeneous dispersion in the PBO matrix. The protonization of different solvents could affect the shape and size of PANI in the composites. With the increase of PANI, the conductivity of composites increases. The conductive behavior of composites was also studied based on percolation threshold and VRH theories. It was found that the VRH models for PANI/MSA/PBO and PANI/H₃PO₄/PBO were different.
