摘要: Abstract Gallium, zinc and cobalt species were immobilized in hollow rectangular-sectioned microtubes of polypyrrole (PPy) electrosynthesized on Nitinol (NiTi) alloy by means two different methods. One them involved the immobilization after PPy electropolymerization other one during electrosynthesis process. The antibacterial activity coating against Escherichia coli (E. coli) was evaluated best results obtained with gallium species. Characterization demonstrated that is incorporated into matrix as Ga3+ ions. film exhibited a good corrosion protection performance.
