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 NO/sub 2/ gas sensitive 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 films with polymeric and phthalocyanines were prepared based on doping-induced deposition effect. These films were characterized by ultraviolet/visible (UV-Vis) spectroscopy. The study on self-assembling mechanism shows 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 NO/sub 2/ gas sensitive properties is studied in this paper.
