中文摘要：

以杉木为基底,采用一步水热法在木材基底上构建超疏水结构,使水滴静态接触角可达151°,滚动角小于5°。并采用湿热老化实验和化学稳定性测试实验初步探究超疏水木材老化性能。实验结果表明,超疏水木材经72 h湿热老化实验之后,表面水滴静态接触角仍可达150.5°,其滚动角小于5°。在强酸溶液中浸泡8 h后水滴接触角仍可达150°,但在强碱溶液中浸泡后水滴接触角急剧下降。

英文摘要：

Taking Chinese fir as substrates, superhydrophobic nanocomposite surfaces were fabricated on wood substrates via a one-step hydrothermal process, which the static water contact angle （WCA） was as high as 151 ° and the sliding angle was lower than 5° .We used hydrothermal aging and chemical stability experiments to test the durability of superhydrophobic wood. After 72h hydrothermal aging experiments, the static WCA was still as high as 150.5 ° , and the sliding angle was lower than 5° . After chemical stability tests, the static WCA was as high as 150° , but alkali resistance is normal.
