| 中文摘要 | Two kinds of ultrathin dual-layer films, which contain both bonded and mobile phases in ionicliquids layer, were fabricated on silicon substrates by a two-step process. As an anchor layer, (3-aminopropyl)triethoxylsilane (APS) and N-[3-(trimethoxylsilyl)propyl]ethylenediamine (DA) separatelyself-assembled on silicon surfaces, then a few ionic liquids molecules were chemically bonded to thesilicon substrates modified by the self-assembled monolayers (SAMs) to form two-phase structure.The formation and surface properties of the films were analyzed by means of ellipsometric thicknessmeasurement, water contact angle measurement, attenuated total reflection Fourier transform infrared(ATR-FTIR) spectrometry, multi-functional X-ray photoelectron spectra (XPS), and atomic force micro-scope (AFM), It is shown that DA form more densely packed films than APS, and the density of theamino-terminated underlayer largely affects the density of the subsequent bonded ionic liquids layer.The adhesive and nanotribological behaviors of the filmswere evaluated by a homemade colloidal probe.A ball-on-plate tribometer was used to test the microtribological performances of the films. As a result,the two kinds of dual-layer films show the improved tribological properties than the single-layer ionicliquids filmdeposited directly on the silicon surface,which is ascribed to synergic effect between flowablemobile phase and steady bonded phase. In particular, the dual-layer film containing DA-SAM possessesexcellent micro/nanotribological properties characterized by lower friction and higher antiwear abil-ity due to more densely packed bonded phase and a few mobile phases. By studying the influencesof self-assembled underlayer on tribological properties of ultrathin dual-layer film, we might find theway to further improve tribological properties and acquire insights into their potential in resolving thetribological problems of micro-electromechanical systems (MEMS). |
