摘　　要：首先利用氨基封端聚二甲基硅氧烷(APDMS)对蒙脱土(MMT)进行有机改性,再用改性蒙脱土(APDMSMMT)结合气相白炭黑作为填料,修饰室温硫化硅橡胶(RTV-1)构建微-纳米结构,形成超疏水表面。通过红外光谱(FTIR)和X射线衍射(XRD)对改性蒙脱土进行了表征,利用扫描电镜(SEM)和水触角仪(WCA)研究了涂层(APDMS-MMT/SiO_2/RTV-1)微观结构及其疏水效果。结果表明,APDMS改性的蒙脱土层间距由1.24nm增加到1.81nm,使蒙脱土能更好地分散在RTV-1中;2种填料在RTV-1表面构建了微-纳米复合结构,测得涂层的接触角(CA)为156°,滚动角(SA)为6°。Firstly,montmorillonite（ MMT） was modified by amino-terminated polydimethylsiloxane（ APDMS）. Then the silicone rubber（ RTV-1） micro-nanostructure was constructed by the modified montmorillonite（ APDMS-MMT） and fumed silica as a filler,formed a super-hydrophobic surface. The property of APDMS-MMT were characterized by FT-IR and XRD. The coating（ APDMS-MMT/SiO2/RTV-1） microscopic structure and the hydrophobic effect were studied by SEM and WCA. Results indicated that the inter-layer space of APDMS-MMT increased from 1. 24 nm to 1. 81 nm,the montmorillonite had a better dispersion in the RTV-1. Micro-nano composite structure was successfully constructed on the surface of RTV-1 with two kinds of fillers and measured the contact angle of coating（ CA） was 156°,rolling Angle（ SA） was 6°.
