摘要
用聚甲基(3,3,3-三氟丙基)/甲基含氢硅氧烷与烯丙基缩水甘油醚、全氟辛基乙烯进行硅氢加成反应,先制得侧链含全氟烷基和环氧基的氟硅聚合物(PFAMS),再与氨基改性的纳米SiO2进行接枝共聚反应,制备了一种纳米杂化氟硅聚合物(PFAMS-SiO2)并将其用于织物整理,获得了对水静态接触角达160.91°的超疏水棉织物.用红外光谱(FT-IR)、扫描电子显微镜(SEM)、X射线光电子能谱(XPS)和静态接触角测量仪等仪器研究了PFAMS-SiO2的结构、在棉纤维表面的微观形态以及织物的疏水性能.结果显示,PFAMS-SiO2与预先设计的分子结构一致;经PFAMS-SiO2整理的棉纤维表面存在一层低表面能的氟硅疏水膜和大量仿荷叶的纳米微凸起,此即织物达超疏水的主要原因.
Firstly a fluorine-silicon polymer （PFAMS） with pendant perfluoroalkyl and reactive epoxy groups was synthesized by Si-H additional reaction of polymethyl （3,3,3-trifluoropropyl）/siloxane （PFAMS）, allylpolyoxyethy- lene ether （AGE） and perfluorooctyl ethylene （PFOE）. Then nano-hybrid fluorine-silicon polymer （PFAMS-SiO2） was prepared through graft copolymerization with amino modified nano-SiO2 and was applied in super-hydropho- bic finish. Super-hydrophobic cotton fabric with 160.91 ° of contact angle of water was obtained. The chemical structure of PFAMS-SiO2, micro-morphology and hydrophobic property of cotton fabrics were investigated by Fourier Transform Infrared Spectrum （FT-IR）, X-ray photoelectron spectroscopy （XPS）, scanning electron microscopy （SEM） and static contact angle analyzer, respectively. The results showed that the structure of prepared PFAMS- SiO2 was consistent with the designed structure. A hydrophobic fluoro-silicon film with low surface energy and many lotus-leaf-like micro-nano scale tubercles were coated on the surface of cotton fabrics, which was responsible for the superhydrophobic cotton fabric.
