Comparative Studies on the Synthesis of Polypyrrole through Polymerization Reaction between Batch and Continuous Processes

Comparative studies on conductive polymer of Polypyrrole (Ppy) synthesized through oxidative polymerization in batch and continuous techniques is reported. The common step for the preparation of solutions consisted of mixing between monomer and ammonium peroxidisulphate (APS) solutions with volume ratio 1:1 under an agitation speed of 400 rpm for 4 hours of reaction time. The two different techniques of polymerization resulted in powder of Ppy which confirmed by the standard Fourier Transform Infra Red (FTIR) spectrum. Formation of Ppy occurred in a much faster speed in a batch technique in comparison with that of continuous one. The advantage of continuous process in obtaining the pure Ppy is that it requires a simple washing step with distillate water. Ppy that resulted from a synthesis of the two processes has electrical conductivity value, making Ppy a conducting polymer.
