Preparation and Characterization of Novel Es-Pani/Glucomannan Composite: Study of Conductivity

Abstract

The synthesized of emeraldine-salt-polyaniline composites were synthesized using in situ chemical polymerization to form the ESPANI-glucomannan composites and the ES-PANI-cellulose composites using the batch, and spray method. Polyaniline can be composed of glucomannan and cellulose matrics because they are abundant, cheap, and environmentally friendly. The Ammonium peroxodisulfate (APS) is used as an initiator for the process of oxidative polymerization of aniline and using HCl and HCOOH doping. Characterization of ESPANI-Glucomannan and ES-PANI-Cellulose composites using FT-IR and conductivity test using LCR-meter. The ES-PANI-Glucomannan composite used the HCl doped batch method, and the conductivity values optimum were 3,68 x 10-3 S/cm, the ES-PANI-Glucomannan composites used the HCOOH doped batch method, the conductivity values optimum were 5,87 x 10-4 S/cm, the ES-PANI-Cellulose composites used the HCl doped batch method, the conductivity values were 1,08 x 10-1 S/cm, the ES-PANI-Glucomannan composites used the HCl doped spray method, the conductivity values optimum were 1,23 x 10-7 S/cm, and the ES-PANI-Glucomannan composites used the HCOOH doped spray method, the conductivity values optimum were 9,20 x 10-8 S/cm. The results of the study showed that the highest conductivity values were found for the ES-PANI-Glucomannan and ES-PANI-Cellulosa composites in the batch method of HCl, and HCOOH doping.
