Superhydrophobic Surface and Lubricant‐Infused Surface: Implementing Two Extremes on Electrodeposited NiTiO₂ Surface to Drive Optimal Wettability Regimes for Droplets’ Multifunctional Behaviors

Lubricant‐infused surfaces (LISs) inspired by Nepenthes pitcher plants due to its continuous and homogeneous slippery surface have garnered great attention, which results in high durability, anti‐corrosion performance, self‐healing property, and anti‐fouling properties. Herein, a cooperative‐responsive slippery surface based on chemically patterned myristic acid (MA)‐modified NiTiO₂ superhydrophobic surface (SHPBS) is fabricated by an electrodeposition method. LIS exhibits long‐term durability with lowest corrosion rate (0.10153 mpy) than MA‐modified NiTiO₂ (0.12922 mpy) and NiTiO₂ (0.226135 mpy). Furthermore, theoretical investigations of phase‐field simulation with a droplet impact on artificially patterned surfaces with rebound dynamics of liquid droplet to its equilibrium state correspond with SHPBSs and LIS, having contact angle (161° and 116°) and hydrophobicity index α _s (−0.8822 and −0.4329), respectively. Herein, multifunctional applications are incorporated on surface without compromising its corrosion performance, and a computational model is involved to understand the mechanisms of two differing applications. Experimental results also quantitatively agree with the calculated wettability parameters. The work not only unveils the close attention for lubricant selection to create long‐lasting LIS but also provides new insights into designing next‐generation multifunctional surfaces, which could be developed for various applications.
