Electrochemical polymerization of acrylics on stainless steel cathodes

Abstract

ABSTRACT:A cathodic, aqueous-based technique for producing uniform, thin, passive films of poly(methyl methacrylate) and poly(glycidylacrylate) on stainless steel electrodes was developed. The films were chemically characterized by Fourier transform infrared spectroscopy, NMR spectroscopy, and differential scanning calorimetry. The thickness (quantified by ellipsometry) and morphology of the films were dependent on the electrolysis time and potential and were also influenced by the individual monomer properties.

Electropolymerised acrylic coatings for polymer-metal adhesion enhancement

“…The ECP method has been described in detail elsewhere [27,28]. Coatings of poly(methyl methacrylate) (PMMA) and poly(glycidyl acrylate) (PGA) were grown on stainless steel cathodes for various electrolysis times at a potential of ¡0.3 V (vs. Ag/AgCl reference).…”

“…The thickness of the lms varied from 30 to 300 nm, depending on polymerization conditions. The morphology of the coatings was also found to be dependent upon electropolymerisation time and potential as well as individual polymer properties, such as the glass transition temperature (T g ) and solubility [27].…”

“…Previously, we have reported the production of thin, uniform and reproducible PMMA and PGA coatings on stainless steel cathodes from aqueous electrolytes containing dilute concentrations of sulphuric acid and potassium persulphate [27,28]. Cyclic voltammetry (CV) and gel-permeation chromatography (GPC) studies demonstrated that the polymers formed by a cathodic free radical mechanism [28].…”

“…The present article presents the results of the adhesion study and demonstrates that the use of ECP tie-layers can signi cantly affect the behaviour of the joint during fracture and can also result in markedly improved adhesion strengths. Previously, detailed studies of the electrolysis method [27] and polymerization mechanism [28] have been published separately, as such approach was deemed the most appropriate to present the results completely.…”

Electrochemically produced responsive hydrogel films: Influence of added salt on thickness and morphology

“…Electrochemically induced polymerization is a particularly flexible and simple way to produce hydrogel coatings [17][18][19][20][21][22]. Polymerization is triggered by the decomposition of an electro-active initiator at the cathode.…”
