Abstract

Two methods for preparing organic polymer sub-micrometer thin films, electropolymerization and low pressure chemical vapor deposition, are discussed. The influences of the mononer concentration, the electrolytic concentration, the current density and the electrolytic time on polypyrrole sub-micrometer thin films are studied. In addition, the influences of the driving voltage, oxide concentration and solvent are discussed for LPCVD polypyrrole films. The NH₃-sensing properties of films of different thickness are tested and studied. The molecular structure of polypyrrole and microstructure of films are analysed by elemental analysis and FT-IR. The NH₃-sensing mechanism is discussed
