Abstract
Plasma polymers deposited from 2-iodothiophene in a microwave plasma reactor are analyzed by XPS and FTIR. To get direct information about the fragmentation mechanism in the plasma optical emission spectroscopy (OES) was used. The electrical conductivity of the coatings was measured. The plasma polymer coatings had an electrical conductivity up to 10high-1 Scmhigh-1. Concerning the oxidation stage of the iodine, Isub3highminus and Isub5highminus were identified as the dominant spezies by XPS. The FTIR-spectra of the deposited plasma polymers showed a good similarity to that of electrochemical, deposited poly(thiophene). This is a strong indication that their chemical structure is similar to that of electrochemical deposited films.
