Resumen:
Abstract Copper species immobilization in hollowrectangular-sectioned microtubes of polypyrrole (PPy)electrosynthesized on 316L stainless steel was carriedout using two different methods. One of them involvedthe immobilization after the PPy electropolymerizationand the other one during the electrosynthesis process.The electrodes modified with copper species were rotatedat different speeds in well water under open-circuitpotential conditions. The release of copper species fromthe PPy matrix and the antibacterial activity againstEscherichia coli were analyzed. The obtained resultsdemonstrate that the amount of copper species releasedas well as the bactericidal effects against E. coli increaseswith rotation speed. The PPy coating modifiedwith copper species after the electropolymerization reactionexhibited the best performance in terms of antibacterialactivity and corrosion protection. These
