Abstract

Tin doped indium oxide (ITO) coatings have been deposited on epoxy resin and glass substrates by low tem-perature (70 °C) RF magnetron sputtering. Influence of different process parameters on coating morphologicaland electrical properties has been studied. Epoxy resin surface roughness influence on coating microstructurewas also investigated. We have found that: (i) deposition chamber oxygen content is the main parameter af-fecting surface electrical resistance, (ii) microstructure and electrical properties are similar in both glass andpolymeric smooth substrates; in the latter the substrate stability (type of polymer and degree of cure) is im-portant to prevent microcracks formation as a result of stress release after deposition, and (iii) rough substratespresent a non-uniform microstructures with formation of clusters of crystallites with various orientation.
