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.
