摘　　要：采用温和的湿化学法在涤纶绸缎的表面生长一层取向排列的氧化锌纳米棒阵列。利用X射线衍射仪和场发射扫描电子显微镜对产物进行结构分析和表面形貌观察,通过液滴形状分析系统及纸片法抑菌实验对其湿润性和抑菌性进行表征和测量。结果表明:经氧化锌纳米棒表面改性的涤纶绸缎与水的接触角达到148°,展现出良好的超疏水性能;同时,经取向氧化锌纳米棒阵列改性后的涤纶绸缎对致病性大肠杆菌、金黄色葡萄球菌等细菌表现出了良好的抑制作用。该产品在服装和包装等行业有着诱人的应用前景。Superhydrophobic terylene satin modified with aligned zinc oxide （ZnO） nanorods was prepared by a tepid-temperature wet chemical route.Structure and morphology of product were characterized by X-ray diffractometer and field-emission scanning electron microscopy.Drop shape analysis system and paper-disk method was used to test its wetting and antibacterial properties.Results showed that the nanorod-modified terylene satin had a water contact angle of 148°,which showed a good hydrophobicity.Meanwhile,bacteriostatic test indicated that the modified terylene satin with aligned ZnO nanorods had a good inhibiting activity to pathogenic escherichia coli and staphylococcus aureus etc..Therefore,the product has an attractive application prospect in garment and packaging industries.
