ABSTRACT
ABSTRACT: Polyaniline (PANI) and Polymethylmethacrylate (PMMA) blend films were prepared from homogeneous solutions in formic acid, which serves both as a dopant as well as a solvent. The absorption spectra revealed that formic acid processed PANI and its blends with PMMA to be deprotonated in atmospheric conditions. Stability studies were done in three ways: with and without an additional protonating agent, Camphoursulphonic Acid (CSA), and with an addition of a plasticizer to the host matrix. The results showed that the presence of CSA imparts stability or resistance against deprotonation.
