Blending Compatibility Between Polyaniline and Polyvinyl Alcohol

In this paper,polyaniline(PAN) was synthesized from aniline by emulsion polymerization.The PAN was dissolved by N-Methyl-Pyrolidone and the polyvinyl alcohol(PVA) was dissolved by water,and then the PAN-PVA blend film was prepared by the casting process.The compatibility and solution mixing of blend film were studied by the differential thermal analysis and the scanning electron microscope.The results showed that the compatibility of blend film was good.And the electrostatic shielding effect of PAN-PVA blend film was discussed elementarily.
