Optical and structural properties of BTCA doped polyaniline nanoparticles at room temperature

Abstract

BTCA doped Polyaniline was synthesized by in-situ chemical polymerization method at room temperature. BTCA  acts as a dopant and soft template for thesynthesis PANInaoparticles.. The prepared samples were characterized by FT-IR, XRD, SEM and PL. FT-IR spectrum confirms the presence of dopant in the polyaniline structure. The optical band gap was found to be 1.90 eV. X-ray diffraction patterns showed crystalline structure due to planar nature of benzenoid and quinoid functional groups.  The intensity of the peak reflections are (100) and (110) planes. spherical agglomerate like morphology. PL study shows emission peak at 420nm.
