✦ Synopsis

The e †ect of surface resistance of substrate and concentration of monomer on the properties of electrochemically deposited poly(N-methyl aniline) Ðlms has been investigated. The UVÈvisible spectra of the Ðlms show enhanced selectivity in the formation of the conducting phase (approximately 860 nm) of polymer on lower surface resistance substrate over those with higher (10 )/K) surface resistance

The magnitude of selectivity increases with concen-(50 )/K). tration of monomer. These results are further supported by IR analysis of the samples. From morphological studies it is noted that the Ðlms deposited on substrates exhibit an overall granular nature irrespective of concentra-10 )/K tion of monomer. In the case of Ðlms deposited on substrates sequential 50 )/K changes in patterning are observed with increasing concentration of monomer. Two redox couples are observed in the cyclic voltammograms together with distortion of peak potential in the Ðlms obtained on higher surface resistance substrates.
