Morphology of conducting polymeric coatings: Quantitative comparison between theory and experiment

Abstract

The density profile of electrosynthesized polymeric layers on carbon fibers is obtained from gravimetric and scanning electron microscopy (SEM) data. The coating density ρ is found to decrease with increasing radial distance, r, subject to the power law ρ(r)∝1/√r. Based on a modified diffusion-limited aggregation (DLA) model, it is shown that lattice Monte Carlo simulation of the coating process predicts the experimentally observed power law exponent. © 2003 Elsevier Science Ltd.
