采用银镜反应及分子自组装技术，在竹材表面原位负载一层纯单质银纳米粒子，赋予竹材导电功能，再经十七氟癸基三甲氧基硅烷（FAS-17）的进一步处理，制备出具有导电功能的仿生超疏水竹材试样，并通过实验观察研究了其稳定性及耐久性。结果表明，制备竹材表面拥有亚微米/纳米二维等级粗糙结构，该结构协同低表面能物质FAS-17共同决定了竹材的超疏水性，竹材表面与水的接触角为155°，滚动角小于10°；制备竹材能够抵抗pH 1~14溶液及强浓度NaCl溶液，且经强烈的溶液搅拌及蒸煮，依旧保持超疏水性和导电性。
The silver nanoparticles are successfully deposited in situ onto the surface of the bamboo through the silver mirror reaction, which makes the intrinsically insulating bamboo conductive. With a further modification by the fluoroalkylsilane(FAS-17), the bamboo timber covered by Ag nanoparticles shows the superhydrophobicity with a water contact angle of 155° and a sliding angle less than 10°. The X-ray diffraction results indicate that the coating on the surface of bamboo is only composed of silver crystals. The scanning electron microscope studies reveal that the coatings possess two dimensional hierarchical structures comprising of the submicron scale papilla and the nano scale granules. The synergistic effect of the submicro/nano binary structure and the low surface energy layer is responsible for the superhydrophobicity of the bamboo surface. Moreover, the study of the stability and the durability of the superhydrophobic bamboo shows that the modified bamboo has a durable superhydrophobic property even under the corrosive solutions including the acidic, alkali and NaCl solutions with different molar concentrations. Especially in harsh conditions of boiling water or intense water stirring, the modified bamboo keeps its superhydrophobicity and high conductivity.
