Electropolymerised acrylic coatings for polymer-metal adhesion enhancement

Abstract

Electrochemical polymerisation (ECP) of acrylic monomers produces thin coatings on metal substrates and is a potentially useful method for forming adhesion promoting tie-layers at a polymer-metal interface. Uniform, passive lms of poly (methyl methacrylate) and poly (glycidyl acrylate) have been formed via a cathodic free radical mechanism on stainless steel electrodes from aqueous electrolytes. The thickness of these lms was found to increase with electrolysis time and the passive nature has been demonstrated by cyclic voltammetry studies. Adhesion tests were performed to compare the adhesion strength and failure mechanisms of various adhesives to coated and uncoated stainless steel substrates. The results indicate that ECP tie-layers can signi cantly increase the adhesive bond strength and alter the failure mechanisms observed. Electropolymerised acrylic coatings on metal substrates are thus seen as a promising approach for pretreatment of metals for adhesion enhancement.

“…4. Indeed, PEO and PMMA bands can be easily identified (see the corresponding band values obtained from literature in Table 1) [20,21,27,[29][30][31]. It can be noted that no such bands are present in the FTIR spectrum obtained from the as-prepared TiO 2 nt sample, which displays just the Ti-O-Ti stretching mode of TiO 2 at less than 1000 cm À1 .…”

“…Electrochemical polymerisation (ECP) is a powerful technique for depositing thin passive films onto materials for corrosion protection and adhesion enhancement. It is also widely adopted to produce highly pure polymer films for applications in electrocatalysis, micro-optoelectronics, and photo-electrochemistry [20][21][22][23][24][25][26]. Depending on the role of the working electrode anode or cathode, the electropolymerization mechanism can be cationic, anionic, or free radical.…”

Direct Electropolymerization of Copolymer Electrolyte into 3D Nano-Architectured Electrodes for High-Performance Hybrid Li-ion Macrobatteries

“…Electrochemical polymerisation (ECP) is a useful technique for depositing thin, passive films onto materials for corrosion protection and adhesion enhancement. It is also widely adopted to produce conducting polymer films for applications in electrocatalysis, microelectronics, and photo-electrochemistry, to mention but a few (16)(17)(18). An electropolymerization mechanism can be cationic, anionic, or free radical, depending upon whether the cathode or anode is used as the working electrode, and upon the choice of reaction system.…”
