Molecular Lubrication Synergized with Ionic‐Covalent Interlocking Network: Toward Anti‐Freezing Elastomers with Ice‐Adhesion Resistance and Retarded Ice Nucleation

ABSTRACT Traditional anti‐icing coatings achieve anti‐icing functionality primarily by sacrificing surface structures or lubricants, yet their rapid failure under mechanical stress and freeze‐thaw cycles remains a fundamental bottleneck restricting long‐term practical applications. To address this challenge, inspired by the ‘combine toughness with softness’ concept, this study proposes a strategy integrating ‘function‐structure synergy’ with ‘energy dissipation‐damage tolerance’. Via multiple hydrogen bonds, molecular‐level chemical integration is realized between the antifreeze lubricant component (glycerol) and the dual‐network framework (covalent polyacrylamide network/sodium alginate‐zinc ion network), successfully constructing a non‐sacrificial dual‐network anti‐icing/deicing hydrogel (PS). This design endows anti‐icing capability as an intrinsic material property, thereby eliminating the leaching of functional components. The resultant PS hydrogel exhibits an extremely low ice adhesion strength of 0.637 kPa. Moreover, its unique dynamic network buffers external stress through efficient energy dissipation, ensuring structural integrity. Environmental simulation tests demonstrate that under harsh conditions, the PS hydrogel displays significantly enhanced long‐term anti‐frost performance and cyclic durability on power line and wind turbine blade models. This research not only offers a high‐performance material for extreme environmental protection but also establishes a new paradigm for developing next‐generation durable anti‐icing/de‐icing materials through its integrated design and energy dissipation concepts.
