Development of highly durable superhydrophobic and UV-resistant wood by E-beam radiation curing

Developing a practical strategy to fabricate an anti-abrasion and durable superhydrophobic wood surface with ultraviolet (UV) resistance has great significance for expanding the application of natural wood. In this study, robust layer hierarchical micro/nano-roughness structure was modified on through in-situ mineralization polymerization using simple sol–gel method along efficient electron beam (EB) curing technology. Hydrophobic agent (polydimethylsiloxane, PDMS), crosslinking monomer (?-methacryloxypropyl trimethoxysilane, MAPS) form new covalent bonds between TiO2 particle substrate after EB radiation, which endows superhydrophobicity remarkable UV surface. The as-prepared exhibited water contact angle approximately 165.7° obvious repellency many aqua-phase liquids (cola, strongly acidic, alkaline droplets etc.). Furthermore, micro/nano-protrusion structures remained unchanged micro/nano particles aggregated tightly under harsh external environments (sandpaper abrasion and, ultrasonic treatment), confirming desirable mechanically performance After 18-day accelerated weathering test, conspicuously retained discoloration maintained its exceptional toward water. biomimetic excellent mechanical durability reveals potential in furniture architecture fields.
