A Self‐Adaptive Composite Lubricated Coating With Lubrication‐to‐Superhydrophobic Transition for Sustainable Icephobicity

Ice accretion threatens critical infrastructure, yet conventional lubricated surfaces suffer from irreversible failure due to lubricant depletion. Herein, we propose a self‐adaptive composite coating (PSPE) that achieves sustainable icephobicity via a lubrication‐to‐superhydrophobic transition. The coating was fabricated by synthesizing a PDMS‐based polyurethane matrix, incorporating perfluoropolyether (PFPE) grease, and constructing a hierarchical rough structure with micro/nanoparticles. Benefiting from this design, the PSPE coating withstands more than 1700 Taber abrasion cycles, 2500 h of UV aging, and thermal treatment at 350°C. Crucially, upon wear‐induced lubricant loss, the coating spontaneously transitions from a low‐friction lubricated state to a superhydrophobic state, maintaining a low ice adhesion strength (<100 kPa) over 12 icing/de‐icing cycles. This work provides a feasible strategy to mitigate the lubricant depletion problem of conventional lubricated surfaces and to extend their anti‐icing service life.
