中文摘要	A self-assembled triple-layer ﬁlm was grafted onto a silicon surface with a simple three-step method. Firstly, 3-glycidoxypropyltrimethoxysilane molecules were self-assembled on silicon surfaces, then coupled to 3-aminopropyltriethoxysilane through a surface ring-opening reaction, and ﬁnally octadecyl- trichlorosilane (OTS)molecules were attached to the resultant alkoxysilane-terminated surface via Si–O–Si bonds. The structure and morphology of this triple-layer ﬁlm were characterized with various techniques, such as contact angle measurement, ellipsometry, X-ray photoelectron spectroscopy, and atomic force microscopy (AFM). The inﬂuence of different surface chemical groups on surface adhesion properties was identiﬁed using the AFM force-volume technique. The micro- and macro-tribological properties of the triple-layer ﬁlmwere evaluated by friction forcemicroscopy and a ball-on-plate tribometer. The triple-layer ﬁlm shows good adhesive resistance and can greatly reduce the micro- and macro-friction force. Moreover, compared to self-assembled monolayer of OTS, this triple-layer ﬁlm exhibited much better wear-resistance. This improvement was mainly ascribed to the network structure of a lateral cross-linked polysiloxane layer formed within the ﬁlm which can enhance the stability of the ﬁlm.
