Abstract
Polypirrole (PPy) is one of conductive polymer material has been success sinthesized through polymerization process using chemical oxidative reaction by batch polymerization technique. The synthesis was conducted at room temperatur with agitation speed within 300-500 rpm. The certain amount of pirolle monomer was reacted with ammonium persulphate in the aquaeous media. Demineralized water is the only one solvent was involved in the reaction. The presence of 0%, 1% and 2% of Polyvinyl alcohol (PVA) in the synthesis of PPy was investigated. Washing process found maximal after four times washing indicated by FTIR spectrum, phisical appearance, color and conductivity value of the filtrate of residual washing treatment. While the synthesized PPywith presence of PVA obtained higher conductivity compare when PVA free. The conductivity value was 57,000, 56,000 µs/cm for additional 1% and 2% of PVA respectively. It is significantly increased when PVA free involved in the reaction. Other supporting characterization during synthesis was conducted such as pH measurement, density, viscosity, temperature and colour degradation observation. The appearance of PPy when presence PVA is being emulsion and different when absence of PVA which obtained powder or solid form of PPy. Black polymer emulsion with various viscosity of PPy was observed completely.
