摘要
Abstract
The antibacterial precursor was prepared by loading Zn2+ on the white carbon black ( WCB) substrate through water bath heating and stirring, and then the white carbon black-zinc inorganic antibacterial agent ( WCB-Zn) was obtained after the calcination of antibacterial precursor, meanwhile, the antibacterial coating was added to the coating to prepare the antibacterial coating.The preparation conditions including the concentration of Zn2 +, solid content of WCB, pH value, and calcination temperature and time were investigated and optimized.Moreover, the properties of inorganic antibacterial agent and antibacterial coating were also tested and characterized.The results show that both the WCB-Zn and antibacterial coating show good antibacterial properties.The minimal inhibitory concentration (MIC)of WCB-Zn on E.coil and S.aureus is 19 mg/mL and 6 mg/mL respectively, and the bacteriostatic rate of antibacterial coating with 8wt% WCB-Zn added against E.coil and S.aureus is 90.48% and 98.77%respectively.关键词
