Molecular structure, optical, electrical and sensing properties of PANI-based coatings with silver nanoparticles deposited from the active gas phase

摘要

The plasma chemical solvent-free method of doped and nanocomposite polyaniline-based (PANI-based) conductive coatings deposition was elaborated. Molecular structure, morphology, optical, electrical and sensing properties of PANI-based coating were investigated by Fourier transform infrared, UV-vis, impedance spectroscopy methods and transmittance electron microscopy. The synthesized PANI-based coatings containing silver nanoparticles have a partially doped structure with low variation in size of oxidized and reduced PANI units.
