Chemical Preparation and Characterizationof Polypyrrole-Polylactic Acid Conductive Composite Membranes
Abstract: Conductive polypyrrole(PPy)-polylactic Acid(PLA) composite membranes are prepared with chemical method. Membranes have been characterized by Fouier transform infrared spectroscopic(FT-IR) and scanning electron microscopy （SEM).The conductive stability of membranes has been measured by home-made multiwell direct current electrical stimulating system. The results show PPy nanparticals network embeds in PLA matrix and the conductive stability of membranes sustains in the range of 28μA~35μA between the observation time of 560h to 1146h.
