Formation the Polypyrrole / Chitosan / Polylactic Acid Microencapsules

Abstract:

The emulsion of chitosan in acetic acid aqueous and poly lactic acid in chloroform was spray-dried to obtain the chitosan/poly lactic acid microencapsules (CS-PLA). The polypyrrole / chitosan/ polylactic acid microencapsules were prepared by polymerization pyrrole on CS-PLA. The structures and the morphologies of microencapsules were characterized by FTIR, SEM, TGA and four probes technique. The results showed that multilayer polypyrrole were formation on the surface of CS-PLA microencapsules, the microencapsules had 3.0-8.0 μm diameters with smooth surface, and the electrical conductivity value was 1.03×10^-3 S/cm.
