| 摘 要： | 首先以棉纤维为主要原材料,通过一步浸渍将聚乙烯醇-二氧化硅粒子(PVA-SiO2)复合物涂覆在棉纤维表面;然后对其进行疏水改性,制得一种超疏水吸油材料。通过扫描电子显微镜(SEM)和水接触角(WCA)测试对改性纤维的表面结构及润湿性进行了分析表征。研究了PVA和SiO2纳米粒子的质量分数对纤维吸油性能的影响,并评价了改性纤维的疏水性、润湿耐受性、吸油速率和重复使用性能。结果表明:棉纤维经过PVA-SiO2复合物涂覆后具有稳定的超疏水性,吸油量比改性前显著提高,对正己烷、甲苯和氯仿的吸油量分别提高了47%、18.6%和26.2%。

| Abstract: | Firstly,taking cotton fiber as the substrate,polyviny alcohol(PVA)-SiO2 composites were coated onto the fiber surface via the one-step immersion.Then,the resulting fiber was modified to be hydrophobic.Finally,superhydrophobic oil-absorption material was obtained.The surface morphologic structure and wettability of coated fiber were investigated using Scanning Electron Microscopy (SEM) and Water Contact Angle (WCA) analysis.Effects of PVA and SiO2 nanoparticles mass fraction on oil-absorption property of the fiber were studied,and the hydrophobic property,wetting durability,oil-absorption rate,and reusability were also evaluated.Results indicate that cotton fiber modified by PVA-SiO2 has stable superhydrophobicity and the oil absorbency of the coated fiber is significantly improved compared with that of raw fiber,with increase rates of 47%,18.6%,and 26.2% in oil absorbency for n-hexane,toluene,and chloroform,respectively. |
