Experimental observation on the bactericidal effect and metal corrosion of a nano disinfection coating
Objective To evaluate the bactericidal effect and metal corrosion performance of a nano disinfection coating.Methods Suspension quantitative killing test and metal corrosion test were used to evaluate the bactericidal effect and metal corrosion performance of the nano disinfection coating.Results The killing logarithm values of Escherichia coli and Staphylococcus aureus were all above 5.00,and the killing logarithm values of Candida albicans were above 4.00 after treated with the nano disinfection coating for 5 min.The nano disinfection coating had basically no corrosion or mild corrosion to stainless steel,carbon steel and copper,and had moderate corrosion to aluminum.Conclusion The nano disinfection coatings has a good killing effect on bacterial propagules and is less corrosive to metal materials.
