摘要: 采用溶膠-凝膠法和浸漬提拉法在不銹鋼板上制備了含銀的二氧化硅薄膜.利用X射線衍射儀(XRD)分析了膜層的組成,通過測試接觸角研究了薄膜的親水性,測試了薄膜對質量分數10%的FeCl₃溶液的耐腐蝕性能,并對覆膜不銹鋼的抗菌性和附著性進行了測定.結果表明:采用溶膠-凝膠法可在不銹鋼基板上制得含銀的SiO₂抗菌膜,經過10min氧化處理和5次提拉,并經熱處理后,抗菌膜與不銹鋼結合牢固,親水性和耐蝕性提高,對金黃色葡萄球菌抑菌率達到100%.

Abstract: A Ag-SiO₂ film was prepared on a stainless steel surface using sol-gel method and soak-lifting method. The structure of the film was studied by X-ray diffraction analysis, the hydrophilicity was characterized by measuring the contact angle, the corrosion resistance was determined in a 10% FeCl₃ solution, and the adhesion properties and antibacterial performance were tested. It is shown that the antibacterial Ag-SiO₂ film can be obtained on the stainless steel by sol-gel method. After oxidization for 10 min and five times dip-coating, as well as heat treatment, the film is firmly bonded with the stainless steel. The hydrophilicity and corrosion resistance of the film are improved, and the inhibitory rate to Staphylococcus aureus reaches up to 100%.
