摘要

Abstract

Integrating photoresponsive components into superhydrophobic surfaces remains a challenge because functional species often disrupt the hierarchical micro/nanostructures required for superhydrophobicity. In particular

intrinsically hydrophilic polyoxometalates (POMs) are difficult to incorporate into low-surface-energy systems without compromising their structural integrity and wetting performance. Herein

a fluoropolymer porous coating of phosphomolybdic acid (FPPC@PMA) was fabricated

via

a high-internal-phase emulsion (HIPE) templating strategy

enabling the simultaneous immobilization of hydrophilic POMs and construction of a hierarchical porous fluoropolymer framework. The resulting FPPC@PMA coating exhibited excellent superhydrophobicity with a water contact angle of 152° and remarkable mechanical durability in sandpaper abrasion and tape-peeling tests. Owing to the redox activity of PMA

the composite also displays a sensitive and reversible photochromic response upon ultraviolet irradiation

suggesting its potential applications in ultraviolet (UV) monitoring and information encryption. Molecular dynamics simulations further elucidated the interfacial interactions between the polymer matrix and phosphomolybdic acid clusters

providing theoretical insights into the structural stability of the composite system. This w

ork offers an effective strategy for integrating hydrophilic photoresponsive species into superhydrophobic architectures while maintaining their structural integrity and functionality.
