摘要/Abstract

摘要： 通过溶胶-凝胶法和原位生长法依次在棉纤维表面修饰了TiO₂颗粒和ZIF-67晶体,并进一步在含有薄荷醇和聚二甲基硅氧烷(PDMS)的正庚烷溶液中进行浸渍处理,成功制备了具有丰富微-纳结构的超疏水香料缓释棉纤维,其静态水接触角为153.4°。利用场发射扫描电镜(FESEM)、X-射线光电子能谱(XPS)和接触角测定仪研究了所制备超疏水香料缓释棉纤维的微观形貌、物相组成及疏水性能,并测定了该材料对薄荷醇的缓释性能。研究表明,在空气中静置存放10天后,超疏水香料缓释棉纤维中薄荷醇的保留率高达81.74%,对应的平均释放速率为1.83%/d,其缓释性能显著优于未修饰改性的棉纤维(平均释放速率为6.77%/d)。经水洗后,超疏水香料缓释棉纤维中薄荷醇的损失率仅为2.93%,明显低于未修饰改性棉纤维水洗后薄荷醇的损失率72.08%。

Abstract: In the present investigation, we successfully prepared superhydrophobic cotton fibers featured with rich micro-nano structure and sustained-release capability to fragrance via successive decoration of cotton fiber surface using TiO₂ particles formed by sol-gel approach and in-situ grown ZIF-67 crystals, followed by impregnation with heptane solution that contains polydimethylsiloxane (PDMS) and menthol. The static water contact angle of the as-prepared superhydrophobic fragrance sustained-release cotton fibers was measured to be 153.4°. The morphology, composition and hydrophobic properties of the as-prepared superhydrophobic cotton fibers were characterized by field emission scanning electron microscope (FESEM), X-ray photoelectron spectra (XPS) and contact angle goniometer. The sustained-release capabilities of the superhydrophobic cotton fibers to menthol were investigated. After the superhydrophobic cotton fibers containing menthol were stored in air for 10 days, the retention percentage of menthol in the superhydrophobic cotton fibers was still as high as 81.74%, with the average release rate of 1.83%/d. The sustained-release performances of our superhydrophobic cotton fibers were significantly better than those of pristine cotton fibers (the average release rate: 6.77%/d). After washed with water, the loss of menthol in the superhydrophobic cotton fibers was only 2.93%, which was substantially lower than that in the washed pristine cotton fibers (72.08%).
