Ice accretion poses a severe impact on diverse aspects of human life. Although great efforts have been dedicated to prevent or alleviate ice adhesion the surface substrates by developing various icephobic coatings, it is still needed improve integrated performance. Herein, we present novel strategy prepare poly(dimethylsiloxane) (PDMS) slippage coatings combining soft architecture-driven branched PDMS with partial short PDMS-functionalized polyhedral oligomeric silsesquioxane (POSS) as co-cross-linker, in which silicone oil certain viscosity was added lubricant. The chemical structure, morphology, and durability prepared were investigated concerns for potential anti-icing uses. coating shed light extraordinary shear strength at approximately 11.2 kPa maintained low values below 14 even after 50 icing/deicing cycles. Due elaborate control cross-link density, side chains provided rich storage space entrapped formation interfacial slippage. Moreover, introduction functionalized POSS brought about significantly improved mechanical resistance abrasion elastic modulus. It suggested that promising candidate practical applications.
