Analysis and Comparison of Vapor and Liquid Deposition of Pyrrole on Wool Fiber

Abstract

Polypyrrole/wool composite fiber was prepared by in situ oxidative polymerization from vapor phase and liquid phase pyrrole at room temperature, by using FeCl3 as catalyst. The effect of deposition technique on the surface morphology, mechanical properties and the electrical stability of fibers were discussed. The result showed that deposition technique has a strong effect and fiber prepared by vapor phase deposition has much fine and small granular structure, lower resistance, better mechanical property and electrical stability.
