Abstract
AbstractSlippery liquid‐infused porous surfaces have received great attention in anti‐adhesion applications, and ionic liquids are selected as the infiltrated liquid in recent research due to their non‐volatility. Beyond the complicated steps, infiltrating the viscous ionic liquid within a porous structure is challenging during the conventional fabrication process. Herein, a facile method is proposed to fabricate polyurethane‐based slippery ionic‐liquid‐infused coatings in one step through a phase separation process. The solid structure grows from the ionic liquid through a liquid–liquid phases separation process. The coatings perform excellent anti‐bacterial and anti‐icing properties owing to the biocide nature, lubricity, and low freezing point of ionic liquids.
