Synthesis and characterization of poly(3-aminophenyl phosphonic acid)

Self-doped polyanilines are polyaniline derivatives that the functional groups, such as sulfonic, boronic and carboxylic acid, bound to the polymer backbones. In our studies, we had an experiment about the phosphonic acid as a dopant for polyaniline, and synthesized the self-doped polyaniline bearing phosphonic acid, poly (3-aminophenyl phosphonic acid), in different surrounding solvents. In addition, the self-doped polyaniline bearing phosphonic acid was analyzed it's qualitative and morphology by UV spectrum and scanning electron microscope (SEM).
