논문초록 Liquid repellent surfaces can have significant impact a wide range of fluid handling and transportation, medicine, and as self-cleaning and anti-fouling materials. Traditional design for such liquid repellent surfaces have been inspired by the lotus leaf and rely on the micro/nanostructured surfaces that led to formation of a air-liquid interfaces. However these interfaces are meta-stable so the air layer can escape under damage, leading to failure of the coating. To overcome this problem, inspired by Nepenthes pitcher plants, slippery liquid–infused porous surfaces (SLIPS) have been proposed as an alternative approach. In the SLIPS system, lubricant forms a stable, defect-free and inert interfaces. Here, we fabricated Chitin nanofibers (ChNF) through an aqueous counter collision (ACC) for underlying solid substrates that can stably entrap the lubricant. This process is conceptually simple and biocompatible so therefore may present an efficient synthetic route to slippery surfaces.
