摘　　要：以氧化铜为前驱体,采用液相还原法制备了一种微纳米尺寸抗菌铜粉。SEM、TEM和LPA结果表明:微纳米抗菌铜粉形貌为近球形,平均粒径为~650 nm。抗菌测试表明,该微纳米抗菌铜粉对大肠杆菌和金黄色葡萄球菌的抗菌率均>99%。同时,将该抗菌铜粉作为抗菌剂应用至金属档案柜表面涂层,涂层对大肠杆菌抗菌率>99.99%,对金黄色葡萄球菌抗菌率达到94.46%,防霉等级为1级。Micro-nano sized antibacterial copper powder was synthesized by liquid phase reduction method using copper oxide precursor.SEM,TEM and LPA test results showed that the prepared copper powder exhibit near-spherical with the average size of 650 nm.The antibacterial test results showed that the antibacterial rate of the micro-nano antibacterial copper powder to Escherichia coli and Staphylococcus aureus was more than 99%.Then the micro-nano antibacterial copper powder was applied to the surface coating of metal filing cabinet as antibacterial agent.The test results of antibacterial and anti-mildew showed that the antibacterial rate of the coating to Escherichia coli and Staphylococcus aureus was more than 99.99%and 94.46%respectively,and the anti-mildew grade was grade 1.
