Paper Abstract

Self-assembly as a novel method to prepare ultrathin functional films has drawn more and more attention in recent years. The preparation methods, structure, characterization and NO2 gas sensing properties of polyaniline (PAN) ultrathin films are studied in this paper. Firstly, PAN, bpolyphthalocyanine and polycation were prepared as raw materials for self-assembling PAN ultrathin films. The self- assembled PAN ultrathin flims with polymeric and phthalocyanines were prepared based on doping-induced deposition effect. These films were characterized by UV/visible spectroscopy. The study on self-assembling mechanism show that it is acids that drives the self- assembling process, which is dependent on the PAN solution property, the types of solvents and polymeric acids, the molecular weight of polymers and temperature. At last, the NO2 gas sensing properties is studied in this paper.
