摘要：
Folic acid (FA) was encapsulated with polydopamine (PDA) to form micro-nano structure by self-polymerization, and hexadecyltrimethoxysilane (HDTMS) was used to modify the rough surface to reduce the surface tension of the fabric, thereby endowing cotton fabric with superhydrophobic performance. At this time, the contact angle on the surface of the cotton fabric reaches 151.9°, and the sliding angle reaches 8°. FA can induce the polymerization of DA through π-π interaction and hydrogen bonding. HDTMS reacts with the hydroxyl groups on the surface of the cotton fabric to increase its hydrophobicity. After 1000 times of friction on the surface of the modified cotton fabric, the contact angle remains above 130°, and its physical and mechanical properties are only slightly reduced. While satisfying the basic applications of cotton fabrics, the application range of cotton fabrics can be greatly expanded. © 2021, Editorial Board of Polymer Materials Science & Engineering.
