Abstract :
The chitosan/polyaniline (PANi) semi-interpenetrating network polymers (semi-IPN)s were prepared under different pH conditions. Changes of structural properties were investigated using Fourier transform infrared (FT-IR) spectroscopy and Solid-state 13C NMR. The spectroscopic studies revealed that the PANi had converted to its pH-switched, emeraldine salt (ES) form when prepared from solutions of pH<l. The surface conductivity of the semi-IPN was dependent on the chitosan/PANi weight ratio and on the pH.
