For the lithographic patterning technique, photosensitive thin films comprising polyaniline (PANI) coatings on viologen-grafted low-density polyethylene (LDPE) substrates were first prepared. The composite film was subsequently exposed to UV irradiation through a mask. Under UV irradiation, reactions between PANI and viologen occurred, resulting in the conversion of the PANI to a doped state. The PANI micropatterns were developed by using N-methylpyrrolidinone (NMP) to dissolve the soluble-unexposed (and hence undoped) parts. The use of Ar plasma treatment of the composite film instead of UV irradiation was not successful in inducing the doping reaction between PANI and viologen. On the other hand, plasma polymerization was shown to be another convenient way for the selective surface deposition of aniline polymer on the surface of the LDPE substrate through a mask. The further incorporation of metal/metal ions in both the PANI-viologen and plasma polymerized aniline system was successfully carried out on the micropatterns 关键词: composite materials;doping;integrated optoelectronics;lithography;masks;nanopatterning;plasma materials processing;polymer blends;polymer electrolytes;polymer films;polymer structure;polymerisation;surface treatment;thin films;ultraviolet radiation effects;electroactive polymer patterns;metal incorporation;UV lithographic approach;plasma polymerization;lithographic patterning technique;photosensitive thin films;polyaniline coatings;composite film;UV irradiation;doped state;PANI micropatterns;N-methylpyrrolidinone;Ar plasma treatment;selective surface deposition;aniline polymer;PANI-viologen;plasma polymerized aniline system;masks;viologen-grafted low-density polyethylene
