Effect of Various Dopant HCL Concentration on Electrical Conductivity of Pani-Cellulose Composite with Cellulose Isolated from Reed Plant (Imperatacy lindrica (L.))

摘要

Material of polyaniline conductive were synthesized by chemical oxidative polymerization of aniline with cellulose isolated from freed plant with various concentration of HCl 1 M, 2 M, 3 M, and 4 M. Matrix cellulose isolated from reed plant by delignification method. Chemical oxidative polymerization of aniline was carried out by using K₂Cr₂O₇ as initiator. Effect of various dopant HCl concentration on electrical conductivity of PANI-Cellulose composite was observed. The PANI-cellulose composite with dopant HCl concentration 3 M have the highest electrical conductivity 0,0816 S/cm. Analysis of surface morphology of composite using SEM-EDX showed that polyaniline particle dispersed on cellulose surface.
