Abstract:

In order to explor a green, simple and effective preparation method for making superhydrophobic cotton fabrics, polydimethylsiloxane (PDMS) coating was used to finish a cotton fabric with low surface energy, and then the salt particles were deposited and dissolved to form a rough structure. The effects of the amount of PDMS, salt particle size, deposition time and lasting time of the superhydrophobic properties of the fabric were investigated. The microstructure, element composition and stability of the superhydrophobic surface were characterized by of contact angle measuring instrument, scanning electron microscope and X-ray diffraction energy spectrum. The results show that there are micrometer pits on the surface of the cotton fabric. The static water contact angle (WCA) on the fabric surface is found up to 155.47° with the water slip angle of 5.5°. The WCA of the fabric, after immersing in strong acid and strong alkali solution for 12 h, still reaches 143.91°. After soaking the treated fabric in 60 ℃ water for 60 min, the WCA is 144.43°, and the WAC of the fabric drops by 11.31% only after 20 rubbing cycles. In addition, the superhydrophobic surface displays the self-cleaning function and anti-dyeing effect.
