Polyaniline Synthesis Using Hydrofluoric Acid as Doping Agent: Comparative Evaluation with Polyaniline Doped with Sulfuric Acid

This work focuses on the comparison between the morphological, chemical, and electrical properties of polyaniline doped with fluoridric and polyaniline, and doped with sulfuric acid. The FT-IR, XRD, and SEM/EDS results indicate that the use of hydro-fluoric acid as doping agent does not provide meaningful changes in the crystalline and morphological structure of polyaniline. Although, the inclusion of F- type counter-ions from the doping process with HF provide more compact, denser, and with higher electrical conductivity polymeric matrices.
