Abstract

Abstract: BP-GO-AgNPs antibacterial composite coating was prepared by adding BP-GO-AgNPs antibacterial composite powder to epoxy resin. The effects of different amount of BP-GO-AgNPs composite powder on the surface hydrophilicity, substrate adhesion and bacteriostasis of the coating were investigated. SEM and contact angle tests are used to observe the micro morphology of the coating surface and judge the hydrophilicity of the coating surface. The results show that the hydrophilicity of the coating surface is not significantly changed with the addition of composite powder. The adhesion grade of the composite coating is evaluated by grid method. The results show that the adhesion grade of the composite coating with 1wt% and 3wt% is better, and the grade is grade 0. The antibacterial properties of the composite coating are tested by film method. The results show that the antibacterial rates of the composite coating against Escherichia coli and Staphylococcus aureus increase first and then decrease with the increase of the addition amount. When the addition amount is 3wt%, the antibacterial effect of the composite coating against Escherichia coli and Staphylococcus aureus is the best, the antibacterial rates are 95% and 89.6% respectively, and the antibacterial effect on Escherichia coli is stronger than that on Staphylococcus aureus. Based on the above properties, the optimal amount of antibacterial composite powder is 3wt%.
