Achieving Intrinsically Self-Healing Fabrics with Breathability, Surface Self-Repairing, and Underwater Adhesion via Nanoparticle-Polymer Gel Synergistic Coatings.

ABSTRACT: Self-healing fabrics have attracted increasing attention as a sustainable solution to extend fabric lifespan and reduce material waste. However, most reported self-healing fabrics rely on extrinsic systems with limited healing cycles, or intrinsic polymers that compromise breathability due to irreversible layer adhesion. In this work, a simple and scalable dip-coating method is reported to fabricate intrinsically self-healing fabrics that retain their porous structure and air permeability. Commercial fabrics are coated with surface-modified silica nanoparticles (SiNPs) and a polymeric ionic gel (PIG) composed of poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) and ionic liquid ([EMI]⁺[TFSI]^-). The SiNPs enhance coating durability and hydrophobicity, while t
