Abstract
This study developed a method to realise triple resistant effects of new branched molecules for copper surface in aqueous solution. The adsorption of the studied molecules on copper surface was analysed. The results demonstrate that the copper surface adsorbed by the studied molecules showed super resistance effects on Chlorella sp., Escherichia coli and Staphylococcus aureus. The dramatic corrosive suppression of the branched compounds on copper in 0.5 M H2SO4 solution was revealed by the potentiodynamic polarisation and electrochemical impedance spectroscopy at 298 K. By establishing a simple chemical strategy to construct the branched molecules, the multiple inhibition properties of the target molecular adsorption layers on copper can be controlled on the molecular scale.
