Thin films of parent polyaniline (PANi) were produced using the self-assemb
ly (SA) technique, by immersing substrates into solutions of PANi in dimeth
ylformamide and acetonitrile. The adsorbed polymer is undoped which means t
hat the driving force for adsorption was probably H-bonding. Polymer adsorp
tion depends on the polymer solution concentration, immersion time and wash
ing procedures.
