Abstract
The present invention provides super-hydrophobic fabrics and a preparation method thereof, and belong to the field of textiles. The super-hydrophobic fabrics are obtained by finishing Pickering emulsion formed by amphiphilic particles stabilizing low-surface-energy substances in water. Via a one-step finishing method using Pickering emulsion technology, facile preparation of durable super-hydrophobic fabrics is realized. The static contact angle between the finished fabric surfaces and water droplets is greater than 150 degrees, and the water droplets can roll off easily; and after being subjected to 30 times of standard washing tests, the finished fabrics still maintains excellent water repellency. In addition, the Pickering emulsion preparation and finishing process of the present invention are environmentally friendly, pollution-free, facile to operate and widely applicable.
