Abstract

Slippery liquid infused porous surface (SLIPS) is fabricated based on the femtosecond laser induced 3D porous network microstructures by Feng Chen, Qing Yang, and co-workers in article number 1700552. The preparation process of SLIPS mainly includes three steps: femtosecond laser ablation, fluoroalkyl layer modification, and infusion of lubricating liquid. A broad range of liquids could easily slide down the 10° tilted SLIPS, revealing that the resultant SLIPS had excellent liquid-repellent ability.
