摘要
通过旋涂法制备表面粗糙度为(57±1.7)nm的SiO2纳米粒子膜来模拟纳米器件的基底。采用原子力显微镜胶体探针,分别对有无正辛基三氯硅烷修饰时,该体系的纳米摩擦学性能进行评价。结果表明:二氧化硅胶体探针与SiO2纳米粒子膜之间的黏着力和摩擦力均随着法向载荷增加而增大,而经正辛基三氯硅烷修饰后,该自组装膜能显著改善SiO2表面间的摩擦学性能,起到明显减摩擦抗黏的效果。
The substrate of silica nanoparticle film was prepared by spin-coating technology,and the root mean square roughness was found to be（57±1.7） nm.By using colloidal probe atomic force microscope tribological interactions were investigated before and after n-octyltrichlorosilane（C8）functionalization for silica nanoparticle film.The adhesion and friction between silica colloidal probe and nanoparticle film increase with the normal load.When the nanoparticle film was modified with C8 self-assembly monolayer,the adhesion and friction significantly decrease.
