Omniphobic surfaces have been widely used in many applications, especially owing to their self-cleaning property. In this work, polyester fabric was modified to be super-omniphobic with a water contact angle (WCA) of 152° by reducing the surface free energy of the fabric surface via the polymerization of 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl methacrylate (TDM) on a ZnO seed layer grown on polyester which acts as intermediate in combining polymerized TDM into polyester. Two types of fabrics, one with and the other without the seed layer, were characterized using various analytical techniques. The WCA of the fabric with the seed layer was measured to be 153° compared to 142° of the fabric without the seed layer. The modified omniphobic fabric with the seed layer made a contact angle of 132° with SAE 40 motor oil indicating its oleophobicity while non-treated fabric made no measurable contact angle. In addition to that, the treated fabric is omniphobic against milk tea, coffee, coconut oil, and ethanol. The morphological analysis using scanning electron microscopy (SEM) of the treated and non-treated fabrics revealed that the particle size of the seed layer applied fabric was ranging from 100-300 nm and upon the TDM application it became less than 100 nm. Elemental analysis by EDS showed the presence of fluorine in the composite and FT-IR analysis confirmed that the polymerization of TDM has indeed taken place. The polymerization of fluoropolymer was further confirmed by TGA and DSC analyses. The durability of the fabrics was tested and the contact angle of the surface-modified fabric remained unchanged even after 1.5 h washing and 50 cycles of abrasion. The modified fabric is robust and no change was observed in the color of the fabric during the process. More importantly, the fabric modification method in this work is simple, low cost and quick.

憎油表面已被广泛用于许多应用中，特别是由于它们具有自清洁特性。在这项工作中，通过3,3,4,4,5,5的聚合反应来降低织物表面的表面自由能，从而将聚酯织物改性为具有152°的水接触角（WCA）的超疏水性，在聚酯上生长的ZnO晶种层上的6,6,7,7,7,8,8,8,8-甲基丙烯酸三氟甲基氟辛酯（TDM），作为将聚合的TDM结合到聚酯中的中间体。使用各种分析技术对两种类型的织物进行了特征分析，一种具有和没有种子层。与没有种子层的织物的142°相比，具有种子层的织物的WCA为153°。带有种子层的改性全憎织物与SAE 40机油的接触角为132°，表明其疏油性，而未经处理的织物则没有可测量的接触角。除此之外，经处理的织物对牛奶茶，咖啡，椰子油和乙醇具有憎水性。使用处理的和未处理的织物的使用扫描电子显微镜（SEM）的形态学分析显示，施加种子层的织物的粒度为100-300nm，并且在TDM施加时，其变得小于100nm。EDS的元素分析表明复合物中存在氟，FT-IR分析证实TDM确实发生了聚合。通过TGA和DSC分析进一步证实了含氟聚合物的聚合。测试了织物的耐久性，并且即使在1.5 h洗涤和50次磨损循环后，表面改性织物的接触角仍保持不变。改性的织物是坚固的，并且在该过程中没有观察到织物颜色的变化。更重要的是，这项工作中的织物改性方法简单，成本低，速度快。
