摘要
使用奥利弗宝对平纹结构的锦纶机织布进行改性,将改性机织布一侧浸泡在质量分数不同的甲酸溶液中,使用喷涂方式把聚四氟乙烯纳米颗粒喷涂在改性机织布表面,得到一侧表面疏水疏油、另一侧表面疏水亲油的油水分离材料。使用X射线光电子能谱仪、接触角测试仪、场发射扫描电子显微镜等对纯锦纶机织布和改性锦纶机织布中元素含量、吸液性能、形貌特征进行分析和表征,并测试了材料的油水分离性能和力学性能。研究表明:当甲酸质量分数为20%时,制备的油水分离材料具有较高的分离效率,拉伸强度为138.97MPa,耐磨性更高、实用性更强,可将其应用于特殊环境的油水分离。
Abstract
Put the OLEOPHOBOLTM modified hydrophobic-oleophobic tabby nylon weave as substrate material,and one side of the substrate was soaked in different mass fraction of formic acid solution,then using air gun spraying PTFE nano particles on the surface,making the one side hydrophobic-oleophobic,another side hydrophobic-oleophylic asymmetric structure of the oil-water separation materials.The content of each element,wettability and surface morphology properties of the original pure polyamide fiber fabric and resulting fabric were characterized by XPS,contact Angle meter and SEM methods.Meanwhile,its oil-water separation performance and mechanical properties were investigated.Results showed that when the concentration of formic acid solution was 20%,the oil-water separation material has higher separation efficiency,the mechanical strength can reach 138.97MPa.The higher wear resistance and stronger practicability can meet the demand in special circumstances under the condition of oil/water separation using.
