摘要：以硝酸铈铵（CAN）为引发剂，含有乙烯基的聚二甲基硅氧烷（VPDMS）和八乙烯基八硅倍半氧烷（VPOSS）
为原料，对棉布进行接枝聚合疏水改性；在此基础上，利用体系内残留的乙烯基与巯基单体进行点击反应，引
入长链烷基单体和含氟单体。采用 FTIR、XPS 和 SEM 对改性后纤维表面化学结构、形貌进行了表征。结果表
明，VPDMS、VPOSS 成功接枝到纤维表面，且通过点击反应法实现了纤维的二次改性。通过接触角测量仪对
改性后棉布的疏水性能进行测定，发现当使用多乙烯基聚二甲基硅氧烷（MVPDMS 10% ，10%指与硅原子相连的
乙烯基物质的量占硅原子总物质的量的百分比为 10%）与 VPOSS 共聚接枝改性时，改性棉布的水接触角可达
153°，使用全氟癸硫醇（PFDCMC）进行二次改性后，改性棉布的水接触角可达 164°。通过磨耗、耐水洗和耐
酸实验发现 PFDCMC 二次改性棉布疏水性能最优，且具有自修复特性。

Abstract: Hydrophobic cotton fabric was prepared by grafting polymerization using vinyl-containing
polydimethylsiloxane (VPDMS) and octavinyloctasilasesquioxane (VPOSS) as raw materials, and cerium
ammonium nitrate (CAN) as initiator. Then, thiol/ene click reaction was adopted to introduce long chain
alkyl monomers and fluorine-containing monomer onto the fabric that had vinyl remained. The chemical
structure and morphology of the modified fabric were characterized by FTIR, XPS and SEM. The results
showed that VPDMS and VPOSS were grafted onto fibers successfully. Besides, the secondary modification
was realized by thiol/ene click reaction. The hydrophobic properties of the modified cotton fabric were
characterized by contact angle measuring instrument. It was found that the contact angle reached 153° when
the cotton fibric was modified by graft coopolymerization of polyvinyl polydimethylsiloxane (MVPDMS 10%,
in which, 10% means the percentage of molar ratio of the vinyl group attached to a silicon atom to the total
silicon) and VPOSS. While the contact angle reached 164° after the secondary modification by PFDCMC.
The results of abrasion test, laundering test and acid resistant test revealed that PFDCMC secondary
modification fabric had the best hydrophobic performance, and exhibited self-healing property.
