Abstract: The present disclosure is related to a coating method of a long-chain entangled PDMS (LEP) gel in which self-replenishment of a lubricating layer is sustainable. More specifically, it is possible to achieve excellent slippery properties, anti-fouling performance, and anti-icing performance for a long period of time due to sustainable self-replenishment performance of a surface coated with LEP gel, by forming LEP gel impregnated with a low-viscosity silicone oil as a lubricant into the surface of long-chain entangled PDMS (LEP), in which long-chain free polymers are entangled in PDMS networks.

Abstract: The present invention relates to a fatty acid amide-based oleogel containing polymer and a method for preparing same and, more particularly, to a fatty acid amide-based oleogel containing polymer and a method for preparing same, the oleogel comprising: a substrate formed of a polymer of a fatty acid amide having a single double bond and a silicone polymer, or a composition comprising same; and an oleogel surface formed by impregnating the substrate with oil, wherein, in the silicone polymer, first silyl-terminated polydialkylsiloxane is crosslinked with second vinyl-terminated polydialkylsiloxane, and the fatty acid amide is linked to the first silyl-terminated polydialkylsiloxane. Also, the present invention can provide use of the fatty acid amide-based oleogel containing polymer according to the present invention.
