| 目的 基于普通织物材料防水性较差的问题，制备一种具有超疏水涂层的聚酯纤维织物，并对其性能进行研究。方法 以聚酯纤维织物为基材，基于紫外光固化技术通过浸涂法，使用商用气相纳米SiO2颗粒(S-SiO2)、端乙烯基聚二甲基硅氧烷(Vi-PDMS)在织物表面构筑微纳粗糙结构，获得超疏水的织物。采用扫描电子显微镜、水接触角测量仪对其微观结构和疏水性能进行表征，并通过机械摩擦实验对其超疏水稳定性进行考察。结果 当Vi-PDMS和S-SiO2质量比为1∶4时，选择交联剂为三羟甲基丙烷三丙烯酸酯(TMPTA)制备的聚酯纤维织物表面的水接触角可达到151°，滚动角可达9°;且经过40次循环摩擦后，其表面水接触角仍大于140°，具有一定的耐磨性。结论 基于紫外光固化技术，采用操作简便的浸涂法制备的聚酯纤维织物具有优异的超疏水性能和一定的耐磨性，为织物超疏水性能研究提供参考，有望应用于超疏水聚酯纤维织物领域。 |

| The work aims to prepare polyester fiber fabrics with superhydrophobic coatings to improve the poor water repellency of ordinary fabrics and investigate their properties. Polyester fiber fabrics were used as the substrate to obtain superhydrophobic fabrics by UV curing technique and dip-coating method with SiO2 nanoparticles (S-SiO2), terminated vinyl polydimethylsiloxane (Vi-PDMS) to construct micro-nano rough structures on the fabric surface. The microstructure and hydrophobic properties were characterized by scanning electron microscopy and water contact angle measurement, and the superhydrophobic stability was investigated by mechanical friction experiments. When the mass ratio of Vi-PDMS and S-SiO2 was 1:4, the surface water contact angle of the polyester fiber fabric prepared by selecting the cross-linking agent trimethylolpropane triacrylate (TMPTA) could reach 151°, and the rolling angle could be up to 9°. After 40 times of cyclic friction, the surface water contact angle of the polyester fiber fabric was still greater than 140°, which had certain abrasion resistance. The polyester fiber fabrics prepared by UV curing technique and easy-to-operate dip-coating method have excellent superhydrophobicity and certain abrasion resistance, which provide reference for the study of superhydrophobicity of fabrics and are expected to be applied in the field of superhydrophobic polyester fiber fabrics. |
