摘要：Using the layered channels of wood and its unique mesoporous microstructure, hexaconazole, polydopamine (PDA), and hexadecyltrimethoxysilane (HDTMS) were grown and deposited in-situ on the surface and interior of wood. Using this method, a superhydrophobic wood composite with decay resistance was prepared. Hexaconazole inhibited wood fungal decay, and the mass losses of wood were 0 and 0.06% with a retention of 140 g/ m3 after laboratory decay tests for 12 weeks by using Trametes versicolor and Gloeophyllum trabeum, respectively. More importantly, through the oxidative self-polymerization of PDA, the adhesive PDA anchored hexaconazole nanoparticles to form a stable core-shell structure that increased the surface roughness of wood. In addition, based on the association of PDA with hydrophilic -OH groups in cellulose and hemicelluloses in wood, longchain HDTMS was deposited on the surface of wood to form a superhydrophobic multifunctional wooden material with a water contact angle (WCA) of 154 degrees. Based on its multifunctional and inherent durability, the wood also showed good chemical stability and resistance to UV, high- temperature, and high-humidity environments.
