A surface and electrochemical study of polypyrrole coated on stainless steel and copper
J. Liesegang,N. Brack,P. J. Pigram,W. Prissanaroon 한국물리학회 2004 Current Applied Physics Vol.4 No.2-4
The micro-contact printing process (l CP) oers an alternative route for the formation of conducting polymer structures onvarious substrates for application in polymer-based electronic devices. Understanding the surface and interface chemistry of thepolymer/substrate system is a vital element in the production of adherent polymer patterns vial CP. In the present study, electricallyconducting polypyrrole lms doped with dodecylbenzenesulfonic acid, PPy(DBSA), have been electropolymerised on stainless steeland copper substrates in aqueous media. PPy(DBSA)/metal interfaces and PPy(DBSA) surfaces have been characterised by X-rayphotoelectron spectroscopy (XPS) and time-of-ight secondary ion mass spectrometry (TOF-SIMS). An electrochemical study ofPPy(DBSA) growth has been carried out by cyclic voltammetry (CV). Iron and copper were detected at the polymer/electrodeinterfaces indicating their dissolution from the stainless steel and copper substrates, respectively, during electropolymerisation. Inaddition, a thin layer of DBSA was observed at the polymer/electrode interface. The eect of growth potential on doping level wasalso investigated. Adherent PPy coatings on the metal electrodes have been produced and the doping level tailored for optimisationof electroactive devices produced via l CP.
