摘　　要：用氯仿从荷叶表面提取蜡质,氯仿挥发后蜡质能够在载玻片上自组装形成疏水涂层。扫描电镜观察表明,荷叶蜡质自组装形成的微观结构与新鲜荷叶表面纳米级的管状结构非常类似;静态接触角测试表明,载玻片上的蜡质涂层接触角高达138°±5°;GC-MS分析表明,荷叶蜡质成分主要为长链脂肪烃、脂肪醇、脂肪酸、脂和少量酮。这种疏水表面原则上能按照荷叶蜡质成分及其含量比例关系溶解混合工业原料得到。Waxes were extracted from the lotus（Nelumbo nucifera） leaves by chloroform,the waxes could self-assembled to be hydrophobic coatings on the glass slides after volatilization of chloroform.The results showed that the structures of tubular epicuticular waxes sculptures of the waxes coating investigated by SEM were the same as the fresh leaf surface,the contact angle of a water droplet on the coating was 138°±5°,and lotus leaf waxes were consist of a mixture of alkanes,alcohols,fatty acids,esters and a spot of ketones based on GC-MS analysis.The same hydrophobic coating could form by dissolving and commixing raw materials according to the components and corresponding proportion of lotus leaf waxes in principle.
