摘　　要：以杭白芷提取物和MgCl2为原料制备平均粒径约为25.5 nm的纳米MgO颗粒。采用超声波分散和浸渍法,将纳米MgO负载到亚麻织物上,制备纳米MgO亚麻抗菌织物。以亚麻织物上负载的镁元素含量为指标,通过Box-Behnken响应面法得到纳米MgO负载亚麻织物的最优工艺条件为:50℃反应65 min,振荡速率120 r/min。在该条件下得到的亚麻织物上Mg元素质量分数达218.16 mg/kg。纳米MgO负载后织物白度上升了3.5%,其对大肠埃希菌和金黄葡萄球菌的抑菌率分别为99.98%和99.97%,具有优异的抗菌性能。Using angelica dahurica extract and MgCl2 as raw materials,nano-MgO particles with an average parti⁃cle size of about 25.5 nm are prepared.Nano-MgO linen antibacterial fabric is prepared by loading nano-MgO onto linen fabric using ultrasonic dispersion and dipping method.Taking the content of magnesium loaded on linen fabric as the index,the optimal process conditions of nano-MgO loaded linen fabric obtained by Box-Behnken response surface method are:reaction temperature 50℃,reaction time 65 min and oscillation rate 120 r/min.The mass fraction of Mg element on the linen fabric under this condition reaches 218.16 mg/kg.The whiteness of the fabric is increased by 3.5%after the nano-MgO is loaded,and its antibacterial properties are excellent with 99.98%and 99.97%of antibacterial rates against Escherichia coli and Staphylococcus aureus,re⁃spectively.
