  Abstract

Cotton fabrics are susceptible to contamination in daily use. Herein, this study developed a scalable and benign strategy to impart superhydrophobic and photocatalytic properties to cotton fabrics by impregnating SiO2–TiO2 Janus particles (SiO2–TiO2 JPs) and silicone elastomer polydimethylsiloxane (PDMS). SiO2–TiO2 Janus particles were synthesized by Pickering template method. The obtained cotton fabrics exhibited good superhydrophobic properties with a water contact angle (WCA) of 155° as well as mechanical and chemical stability. The modified fabrics maintained their superhydrophobic properties against 30 cycles of mechanical abrasion, 15 cycles of tape peeling, and 24 h of UV aging. They also had good resistance to n-hexane, acetone, acid/alkali liquids. The degradation efficiency of Rhodamine B (RhB) was up to 63% after 6 h of UV irradiation and still 48% after 5 cycles of degradation. The facile approach in favor of large-scale preparation showed promising potential for wide application of flexible, superhydrophobic cotton fabrics with self-cleaning performance.
