超疏水木材耐久性的提升,将会极大拓展未来超疏水材料的应用领域.本文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°.采用湿热老化实验和化学稳定性测试初步探究超疏水木材老化性能.在经过72小时湿热老化实验之后,该超疏水木材表面水滴静态接触角仍可达150.5°,其滚动角小于5°.经化学稳定性测试,在pH=2盐酸溶液浸泡8小时后水滴接触角仍可达150°.

　　Superhydrophobic surfaces on wood were fabricated and the durability was promoted,which offers an opportunity to extend the range of practical applications for wood resources.In this study,superhydrophobic nanocomposite surfaces were fabricated on wood substrates via a one-step hydrothermal process,the static water contact angle(WCA)was as high as 151°,and the sliding angle was lower than 5°.After 72h hydrothermal aging experiments,the static WCA was still as high as 150.5°,and the sliding angle was lower than 5°.After che...
