Synthesis and characterization of polypyrrole layers on different substrates

Abstract

This work focuses on preparation and characterisation of polypyrrole layers on different substrates. The preparation of polypyrrole layers was carried out by a simple method using ferric chloride as an oxidising agent on several types of substrates - soda lime glass, polyethylene terephthalate foil, and the silicon wafer. The conductivity of the prepared layers was measured, they were then further characterised by an optical microscope, and Raman spectroscopy. By creating a series of models with molecular modeling and their subsequent optimisation, it was possible to calculate and compare the interaction energy of polypyrrole layers on the used substrates.
