摘要：
Using water-soluble coupling reagent N-(3-dimethylaminopropyl)-N'-ethylcarbodiimide hydrochloride (EDC) and N-Hydroxysuccinimide (NHS), small molecules of 3-aminobenzene boric acid (PBA) was grafted onto the surface of palm wax emulsion microspheres (PW), and modified palm wax emulsion microspheres (PW-PBA) grafted with phenylboronic acid functional groups were successfully prepared. First, PW-PBA and polyvinyl alcohol (PVA) were formed into reversible borate, and then silicone resin was added to obtain PW-PBA/PVA self-assembled superhydrophobic cotton fabric. Through infrared spectroscopy, scanning electron microscopy, particle size analysis, contact angle (CA), and powerful testing methods to study the structure and performance of the products. The results show that the interactions between palm wax emulsion microspheres grafted with phenylboronic acid functional groups and PVA polyol were controlled by pH; under pH conditions (pH≥9), the contact angle of the PW-PBA/PVA self-assembled film cotton after hot melt treatment is increased significantly, reaching 122°, when the pH is 9 and the silicone resin mass fraction is above 3%, the contact angle of the PW-PBA/PVA self-assembled film cotton reaches 152° after hot melt treatment to achieve super-hydrophobic effect. The physical and mechanical properties of the finished cotton fabric have been improved. The preparation process of the method is green, environmentally friendly, and low in cost, and has good application value for improving the performance of cotton fabrics. © 2021, Editorial Board of Polymer Materials Science & Engineering.
