Electronic Structure of Metal/Polymer Interfaces: Aluminum on Conjugated Polymers
1991 (English)In: Metallized Plastics 2: Fundamental and Applied Aspects / [ed] Kashmiri Lal Mittal, Springer, 1991, 199-212 p.Chapter in book (Other academic)Text
Aluminum has been deposited on two types of conjugated polymers, polyalkylthiophene and polyaniline. The polymers were in the undoped, neutral form which possesses semiconducting properties. The chemical structure of the metal/polymer interface has been investigated by X-ray and UV photoelectron spectroscopy. Core level spectra indicate that aluminum reacts with the sulfur atom of the polythiophene chain, strongly perturbing the π-electron system. In the case of polyaniline, the interaction with the metal depends on the oxidation state of the polymer. UPS data, combined with the results of band structure calculations, are interpreted in terms of the Al-induced modifications of the π-electron system.
