The silica particles with unique morphology and hydrophobicity have been synthesized 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) studies revealed that the composite coatings possess two dimensional hierarchical structures comprising 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 superhydrophobicity of wood surface. Moreover，the stability and durability of treated wood have been investigated 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 applications for wood resources.
