Herein, a superhydrophilic/air-superoleophobic coating with coral-like porous structures was successfully fabricated via a one-step spraying method by integrating waterborne polyurethane (WPU) and the micro-nano composite particles (F-BN@SiO₂), which were synthesized through in-situ growth of SiO₂ on the boron nitride (BN) surface and subsequent chemical modification with FS-50. The prepared coating exhibited excellent superhydrophilicity/superoleophobicity in both air and water environments (OCA = 152.7 ± 1.3° and WCA = 0°). Compared with the unmodified WPU coating, the wax adhesion force of the WPU/F-BN@SiO₂ coating decreased from 9.954 N to 0.785 N, as the synergistic effect of hierarchical rough structures and low-surface-energy groups enables the coating to form an air film, which weakens van der Waals forces and enhances the repulsion of fluorinated groups, thereby repelling wax crystals into larger aggregates. Moreover, the underwater wax inhibition efficiency of the prepared coating can reach up to 99.86 % due to the rapid formation of hydrated layer to prevent wax crystal aggregation and adhesion. Furthermore, the prepared coating also demonstrated outstanding mechanical and chemical stability even after undergoing 300 cycles of sandpaper abrasion and 3 h immersion in corrosive solutions, which is enabled by the interfacial bonding formed through dopamine self-polymerization between the WPU and composite particles.

However, conventional nanocatalysts are difficult to recover and prone to causing secondary pollution. Highly adsorbent porous xerogels, currently attracting significant attention, face limitations in cyclic applications due to the requirement for external reagents during desorption treatment, and their performance degrades markedly after repeated use. In this study, we present a stable and facile preparation method of high-performance xerogel microspheres loaded with nanoparticles based on electric field intensification technique. A commonly used photocatalytic material TiO₂ and a biocompatible calcium alginate (CA) are used as the model materials for demonstration. It is found that high-performance microspheres with uniform particle size and controllable dimensions can be prepared by adjusting the electric field strength. The TiO₂-loaded CA (TiO₂@CA) microspheres prepared at 6 kV exhibit a 33.92 % enhancement in 1 h purification performance when comparing with pure CA xerogels. Moreover, even under weak light intensity conditions, the purification performance can be enhanced by approximately twofold within 0.5 h as compared to that of TiO₂ nanoparticles. The results confirmed that the synergistic effect between the high adsorption capacity of the CA substrate and the photocatalytic activity of TiO₂ nanoparticles enabled the microspheres to efficiently remove organic dye molecules from both the surfaces and the bulk phase solution. The TiO₂@CA microspheres can be regenerated without external reagents, demonstrating no performance degradation after five consecutive experiments, which proves their outstanding green advantages.
