摘要

In low-temperature environments, ice formation on the surface of cotton fabrics significantly limits their practical applications. To address the aforementioned challenges associated with cotton fabrics, this work developed anti-icing/de-icing and spontaneous de-wetting cotton fabrics using aminopropyl terminated polydimethyl siloxane (AT-PDMS), 1,3,5-benzenetricarboxaldehyde (1,3,5-BTB), and Fe3O4 microspheres. AT-PDMS, due to its low surface energy and excellent flexibility, imparted fundamental anti-icing properties to the fabric. 1,3,5-BTB cross-linked with AT-PDMS through reversible chemical reactions, forming self-healing superhydrophobic coatings on the fabric surface. Additionally, the incorporation of Fe₃O₄ microspheres into the composite coating endowed the fabric with photo-thermal conversion capability, thereby providing the de-icing and spontaneous de-wetting properties. As a results, the composite coatings endow the fabric with excellent superhydrophobic properties, with the water contact angle (WCA) was reached at 161.5° ± 0.7°. Under 0.5 sun irradiation for 7 min, the surface temperature of the finished fabric was increased from 26.4 °C to 107.7 °C, showing outstanding photo-thermal properties. The results demonstrated that the finished fabric exhibits a significantly reduced ice adhesion strength, photo-thermal de-icing and spontaneous de-wetting properties. This approach provides a viable strategy for the development of novel functional textile materials and shows promising application potential in fields such as outdoor apparel and aerospace engineering.
