Preparation of Conductive Response Polyaniline/Polyurethane Orderde Array Thin Film

Polyaniline nano particles and polyaniline/polyurethane composite film were prepared through the template-free method. The ordered array structure of composite thin films with optical property were observed. The proportion of polyaniline/polyurethane in the composite films was discussed, and the change of resistance and absorbance of the thin films was measured in different proportion. In the energized condition polyaniline/polyurethane composite film had morphological changes, shrink trend, and their resistance value became significantly increasing. With the increase of the voltage electricity, the film contraction trend changed bigger.
