Transparent, Electrically Conductive Composites Derived from Polypyrrole and Poly[Vinyl Chloride) by Vapor-Phase Polymerization: Effect of Environment on Polymerization and Reaction Mechanism

Abstract

Transparent, electrically conductive composite films were obtained by vapor-phase polymerization of pyrrole into a poly(viny1 chloride) (PVC) matrix containing FeC13. The effects of water and of organic solvents on the polymerization were investigated. It was found that the conductance of the films increases in the presence of both water vapor and of good solvents or swelling agents for PVC. The conductivity of the films rises with reaction time and so does the rate of increase with higher FeCI3 concentration. The production of HCl was monitored by two methods, the precipitation of AgCl in an aqueous solution of silver nitrate and the increase in conductance of an aliquot of distilled water which had been placed into the reaction ch.smber. On the basis of our experimental results, we propose a reaction mechanism that explains the observed increase of conductance with time. A universal kinetic formula has been *Permanent address:

Preparation of Size Controllable Polypyrrole Sub‐Microcapsules Using SEBS Copolymer as the Building Block

“…Vapor phase polymerization is used for the in‐situ polymerization of pyrrole within a number of different non‐conducting polymers and rubbers 12,13. Ueno et al12 made a conducting composite by exposing poly(vinyl chloride) (PVC)/FeCl 3 blends to pyrrole vapors. There have been a small number of attempts to utilize iron( III ) tosylate as the oxidant in vapor phase polymerization processes of pyrrole 11.…”

Coating of poly(vinyl chloride) nanoparticles with a conductive polyaniline in the presence of various surfactants

“…Ueno and co‐workers prepared conductive blends of poly(vinyl chloride) and polypyrrole (PPy) by using a PVC solution containing FeCl 3 . Films of PVC/FeCl 3 were prepared by partially exposing cast and dried films to UV light to observe the formation of an image that was converted into an electrically conductive form by exposing the film to pyrrole steam .…”

Simultaneous Vapor‐Phase Polymerization of PEDOT and a Siloxane into Organic/Inorganic Hybrid Thin Films

“…Advantageous when considering the coating processability, pot‐life time, and the versatility of substrates, VPP has a strong potential to produce highly transparent and conductive thin films for future electronic applications 9, 10. Since Mohammadi et al11 introduced the VPP technique for the preparation of PPy thin films, a number of studies regarding ICP thin film preparations have been reported 12–15. Among the ICPs, PEDOT thin films can readily be obtained from in situ VPP of 3,4‐ethylenedioxythiophene (EDOT) on various oxidant‐coated plastic or inorganic substrates such as poly(ethylene terephthalate) (PET), polyimide, polyvinylchloride, polystyrene, glass, ITO coated glass, and silicon, etc 16–19.…”
