中文摘要	Nanotribological properties play an important role in many applications, such amicro/nanoelectromechanical systems (M/NEMS) and high-density storage technologies (hard drivers)Therefore, it is important to study the nanotribological properties of these surfaces which are separatedby only a couple of nanometers. Patterning feature or surface texture with micro/nano-scale dimensionis of great importance for solving these problems. In this work, micro/nano-patterned Au surfaces withdifferent topography features were fabricated via a convenient method and then chemically modiﬁedby alkanethiol SAMs for optimization of their nanotribological performance. Surface compositionand morphologies of Au surfaces with different micro/nano-textures and chemical modiﬁcation wereevaluated by XPS, contact angle measurements, 3D non-contact optical microscopy and AFM. AFM/FFMwas used to investigate the nanotribological behaviors of Au surfaceswith differentmicro/nano-textureand corresponding chemical modiﬁcation. Results obtained in this work demonstrated the feasibility ofabricating surface textures with micro/nano-scale cylindrical holes and the possibility of controllingchemical composition on surface to improve the nanotribologcal performance of Au surface. Nanotribological properties of textured Au surfaces were greatly determined by the fractional surface coverageof cylindrical holes and consequent chemical modiﬁcation. Au textured surface with dense cylindricaholes and further chemically modiﬁed with self-assembly monolayer showed signiﬁcantly enhancedhydrophobicity and nanotribological performance compared with Au textured surface with sparsecylindrical holes without chemical modiﬁcation.
