In this study, hydrophobic fabrics with controllable rough surfaces were prepared by treating a polyester (PET) fabric with methyltrichlorosilane (MTS), phenyltrichlorosilane (PTS), vinyltrichlorosilane (VTS), and tridecylfluorooctyltrichlorosilane (PFOTS) using a liquid phase method. The formation mechanism of the fabrics was investigated using X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy. Although the WCA of the fabrics decreased after mechanical abrasion, their hydrophobic surfaces exhibited good durability. Four controllable rough structures were observed and show its unique properties. MTS@PET showed a hollow spherical structure, and hence was found to have potential to encapsulate medicines for health care. On the other hand, PTS@PET showed a hollow bowl-like structure and strong absorbance to water. The TCS/PFOTS@PET with spherical microstructure was amphiphobic, according to that the contact angles of it to water and n-tetradecane were 153.3 ± 3.0° and 133.4 ± 4.5°, respectively. The WCA and sliding angle (SA) of VTS@PET, which showed a nanofilament structure, were 156.4 ± 3.0° and 3.0 ± 2.0°, respectively, indicating that its surface was superhydrophobic.

在这项研究中，通过使用液相法用甲基三氯硅烷（MTS），苯基三氯硅烷（PTS），乙烯基三氯硅烷（VTS）和十三烷基氟辛基三氯硅烷（PFOTS）处理聚酯（PET）织物来制备具有可控粗糙表面的疏水性织物。利用X射线光电子能谱和傅里叶变换红外光谱研究了织物的形成机理。尽管织物的WCA在机械磨损后降低，但它们的疏水表面表现出良好的耐久性。观察到四个可控的粗糙结构，并显示出其独特的性能。MTS @ PET显示出空心的球形结构，因此被发现可以封装用于保健的药物。另一方面，PTS @ PET显示出空心碗状结构和对水的强吸收性。正十四烷分别为153.3±3.0°和133.4±4.5°。显示出纳米丝结构的VTS @ PET的WCA和滑动角（SA）分别为156.4±3.0°和3.0±2.0°，表明其表面具有超疏水性。
