| 摘 要： | 采用机械共混法,通过添加疏水性纳米SiO2对PRTV硅橡胶涂料进行改性,研究了纳米SiO2的添加量对改性PRTV涂层表面疏水性的影响,并探讨了涂层表面的微结构与其水接触角的内在关系。结果表明:利用共混法将疏水性纳米SiO2加入PRTV涂料中,可以制备出具有超疏水性的复合涂料,其涂层的水接触角可由106°提高到150°。

| Abstract: | A super-hydrophobic surface of compound PRTV coating coupled with the hydrophobic-modified nano-silica particles was prepared via mechanical blending method.The effect of adding amount of nano SiO2 on hydrophobic modification of PRTV coating was studied.The relations between the microstructure of sample’s surface and its water contact angle were argued in this study.The results show that a super-hydrophobic compound coating can be prepared by mixing the hydrophobic-modified nano-silica particles with the PRTV coating via mechanical blending method.The maximum water contact angle of the modified PRTV coating increased from 106° to 150°. |

| Keywords: | mechanical blending super-hydrophobic modification structure of lotus-leaf nano-silica silicon rubber coating |
