▎ 摘　　要

The demand for textiles equipped with multiple functionalities is high. This work aimed to develop ultralight versatile protective polyurethane/graphene fabrics with excellent water-protective, antistatic, UV protection and crocking performance using pad knife coating technology. The prepared fabrics were characterized using scanning electron microscopy and Fourier transform infrared and Raman spectroscopies. The effects of graphene and toluene concentrations on the morphological, water-protective, electrical, UV protection and crocking properties were evaluated. Results showed that fabrics coated with 3 wt% graphene had better antistatic property (298.3 kV/1.23 s), good water repellency (80%), outstanding water resistance (153 kPa), relatively high water contact angle (103.2 degrees) and modest crocking and mechanical performance (grade 3, 15.06/11.86 N). Furthermore, UV protection abilities increased from 35.71 to 2000, up to fivefold higher than those of previously reported graphene-based coated fabrics. As a polar solvent, toluene exerted a positive effect on the promotion of molar polarization, improving the antistatic property. The facile coating technology is simple, can be used in versatile protective applications and is suitable for large-scale production. (c) 2020 Society of Industrial Chemistry
