Superhydrophobic wood surfaces had been fabricated via in-situ synthesis of Cu₂(OH)₃Cl nano-flowers. The modified wood surface exhibited improved water repellency as evidenced by an increased water contact angle (163° vs 50 to 75° for the control) and a sliding angle less than 5°. The modified wood surfaces remained hydrophobic after 12 h of exposure to strong acid (pH 2) or alkaline (pH 12), and the as prepared superhydrophobic surface was resistant to mechanical damage via 1000 cycles of tape removal and repeated sandpaper abrasion. The modified wood surface repelled not only water, but also milk, coke, and soy sauce, and showed a self-cleaning function. The results illustrate the promise of generating superhydrophobicity for improving the moisture resistance of timber surfaces. This work developed a simple, low-cost, and durable strategy for creating superhydrophobic wood surfaces, which has potential to be applied in wood industry to expand the service life of wood products.

通过原位合成 Cu ₂ (OH) ₃制备了超疏水木材表面氯纳米花。改性木材表面表现出改善的防水性，这可以通过增加的水接触角（163° 对对照的 50 至 75°）和小于 5° 的滑动角来证明。改性木材表面在暴露于强酸 (pH 2) 或碱 (pH 12) 12 小时后仍保持疏水性，并且所制备的超疏水表面通过 1000 次胶带去除和反复砂纸磨损循环能够抵抗机械损伤。改性木材表面不仅排斥水，而且排斥牛奶、焦炭和酱油，并表现出自清洁功能。结果说明了产生超疏水性以提高木材表面的防潮性的前景。这项工作开发了一种简单、低成本、耐用的策略来创造超疏水木材表面，
