| 摘 要： | 超疏水涂层由于其广泛的应用前景, 近年来备受关注。然而, 利用天然聚合物制备超疏水材料和超疏水涂层仍然缺乏一种简单、经济的方法。本文通过取代反应制备了超疏水性木质素-PFTEOS粉体。由于该粉体与基体无关的特性和优异的超疏水性, 可用于各种基体制备超疏水性涂层。所制备的涂层疏水性极强, 水接触角最高可达169°, 同时具有良好的耐摩擦、耐酸碱、耐盐性能和较好的耐腐蚀性能：经砂纸摩擦循环20次或在1 mol/L HCl、0.20 mol/L NaOH和1 mol/L NaCl溶液中浸泡30 min后, 涂层仍保持超疏水性能, 且接触角大于150°。这种低成本、可降解和可扩展的木质素基涂层在不同领域具有巨大的应用潜力, 并为碱木质素的增值利用提供了一种简单的方法。

| Abstract: | Superhydrophobic coatings have drawn much attention in recent years for their wide potential applications. However, a simple and cost-effective approach is still needed for preparing superhydrophobic materials and coatings using natural polymer. Herein, a hierarchical superamphiphobic Lignin-PFTEOS powder was prepared via a substitution reaction. Owing to the substrate-independent characteristics and excellent super-repellency of the powder, it could be applied to various substrates to fabricate superhydrophobic coatings. The prepared coatings have a huge repellency to water, with a water contact angle of 169°, as well as good friction resistance, acid resistance, alkali resistance, salt resistance properties and quite good corrosion resistance performance. After 20 cycles of sand friction or being immersed in 1 mol/L HCl, 0.20 mol/L NaOH and 1 mol/L NaCl solution for 30 minutes, the coatings still retain superhydrophobic capability, with contact angle higher than 150°. Due to its low cost, biodegradability and scalability, lignin-based coatings have huge potential applications in different fields and provide a simple method for the value-added utilization of alkali lignin. |
