Abstract

SISON, CHRISTIAN PAULO E. University of the Philippines Los Banos, October 2001. Determination of Electrochemical Properties of Polyaniline/Lignin Blends Prepared from Aniline and Coconut Coir Dust.

Adviser: Dr. Norriel S. Nipales

Polyaniline (PANT), an intrinsically conducting polymer, was blended with Klason lignin. PANT was synthesized using chemical and electrochemical methods. Then was blended with lignin, which was isolated from coconut coir dust using the Mason method of lignin isolation. Electrochemical properties of the blend were studied by cyclic voltammetry and resistance measurements. It showed that as lignin concentration increased, a decrease in the current response of blends was observed. Thermogravimetric Analysis (TGA) revealed that the thermal stability of the electrochemically synthesized PANI/lignin blend increased as the amount of lignin increased. Chemically synthesized PANI/Lignin blends showed a different response. A decrease in thermal stability was observed as lignin was incorporated.
