Abstract :

Practical applications of conducting polymers such as polyaniline as membranes are particulary limitedbecause of their poor mechanical properties. However by mixing polyaniline with some conventional insulatingpolymers such as nylon and preparation composite films through solvent casting or blending, it seems to be asuitable way in order to increase the mechanical properties of the conducting polymer films PolyanilineNylons(PAn/Ny) composites were processed fro n formic acid. The preparation conditions were optimized with regardto the mechanical properties. The molar ratio of PAn to nylon has the greatest effect in mechanical properties ofthe composite membranes.Thermal stability of the PAn/Nylon composites (casted on transparent glass fromformic acid) was investigated spectrotrophotometrically (Uv-Vis). Our spectrophotometric analysis shows thatthe polymeric composites are more thermally stable compared to pure PAn.
