摘　　要：针对棉织物的抗菌问题,采用溶胶凝胶-低温热处理法在织物上原位生长ZnO纳米薄膜,赋予织物优良的抗菌性能,并利用热重分析仪、扫描电子显微镜、原子力显微镜和X射线能谱仪等手段对薄膜的成分、形貌和结构进行表征。结果表明:织物表面负载上了均匀连续的ZnO纳米薄膜,负载率约6%,织物表面粗糙度从22.80 nm降至6.81 nm。织物对大肠杆菌和金黄色葡萄球菌的抗菌率超过99.99%,对白念珠菌的抗菌率达到96.20%,具有广谱抗菌性。ZnO薄膜在织物表面有良好的附着性,经过250 min振荡洗涤后,薄膜结构仍保持均匀连续。For the antibacterial problem of cotton fabrics,a two-step method of sol-gel-low temperature heat treatment was used to in-situ grow ZnO nanofilms on fabrics.Thermogravimetric analyzers(TGA),scanning electron microscopy(SEM),atomic force microscopy(AFM)and X-ray energy spectrometry(XPS)were used to characterize the composition,morphology and structure of thin films.Results show that the ZnO nanofilms loaded on the fabric surface are uniform and continuous with a loading rate of about 6%,resulting in a reduction of the roughness of the fabric surface from 22.80 nm to 6.81 nm.The ZnO films remain continuous after 250 min of oscillation washing,which indicates that the films are well bonded to the fabric.The antibacterial experiments show that the fabric has broad-spectrum antibacterial properties,with antibacterial rates of over 99.99%against E.coli and S.aureus and 96.20%against Candida albicans.
