通过溶胶-凝胶法一步合成疏水性且具备独特形貌的二氧化硅粒子，联合聚苯乙烯以滴涂的方式于木材表面仿生合成了稳定性超疏水薄膜。经处理后的木材表面与水的静态接触角为153°，滚动角小于5°。通过扫描电子显微镜照片观察到该复合涂层拥有微米/亚微米的二维等级粗糙结构，该结构协同低表面能物质共同决定超疏水性木材的成功制得。此外，进一步研究了超疏水性木材表面的稳定性和耐久性。结果表明，该超疏水性木材于水、腐蚀性液体（酸液/碱液）、常见有机溶剂中以及一些常见条件下仍保留超疏水特性，为未来木材材料的应用领域扩展提供了有利条件。

The silica particles with unique morphology and hydrophobicity have been synthe-sized via a one-step sol-gel process,which as well as polystyrene was employed in the bionic and stably superhydrophobic coatings with water contact angle of 153° and sliding angle less than 5° on wood surface by a drop-coating method. Scanning electron microscope (SEM) stud-ies revealed that the composite coatings possess two dimensional hierarchical structures com-prising of micron scale papilla and submicron scale granules. The synergistic effect of micron/submicron binary structure and low surface energy layer was responsible for the superhydropho-bicity of wood surface. Moreover,the stability and durability of treated wood have been investi-gated as well,and the results showed that the product possesses superhydrophobic property in a wide extent,such as pure water,corrosive water under both acidic and basic conditions,some common organic solvents,which offers an opportunity to extend the range of practical applica-tions for wood resources.
