中文摘要	Fast development of micro/nanoelectromechanical systems (MEMS/NEMS) and high-density storage technology (HDT)have stimulated the development of new materials that require hydrophobic surfaces with low adhesion and friction. Micro/nanohierarchical structures and chemicalmodiﬁcation are two usefulmethods for improving nanotribological properties ofmechanicalcomponents. In this study, Au surfaces withmicro/nanohierarchical structures were prepared by replication ofmicropatterened siliconsurfaces using PDMS and self-assembly of alkanethiol [CH3(CH2)9SH] to create hydrophobicmicro/nanohierarchical structures and toimprove nanotribological properties of MEMS/NEMS. The effects of nanoscaled roughness (including pillar height and pillar fractionalsurface coverage) and chemicalmodiﬁcation on the wetting and nanotribological properties of surfaces were systemically investigated.Results show that with the increasing of nanoscale roughness and lowering of surface energy, the surface becomesmore hydrophobic,and the adhesive force and friction force are reduced greatly.
