A durable organogel anti-icing material via swelling cross-linked poly(dimethylsiloxane) with liquid paraffin is reported. The surface of the organogel is covered by a thin released layer of paraffin due to the osmotic pressure, which acts as a lubricant and reduces the ice adhesion greatly. Results show that the ice adhesion on the surface of the organogel is as small as 1.7±1.2 kPa (at 0°C) and the low ice adhesion remains even when the temperature is lowered to 0°C. The surface with lubricating liquid paraffin layer exhibits excellent durability, as it shows an ultralow ice adhesion after 35 cycles of icing/deicing and 100 days of exposure in ambient environment. . , , , 30°C1.7 ± 1.2 kPa, 0°C 0 kPa. 00, 35/, ,
