Tribological comparison of three typical wrinkled surface on the elastomeric polymer

Surface texturing has been known as an effective way to improve tribological performance [1]. To obtain given texturing patterns, a variety of conventional fabrication techniques were applied to make desirable surface. Recently surface wrinkling has been utilized as a novel approach to create various and ordered surface structures for mico-fabrication [2, 3]. The preliminary work in friction of wrinkled surface has been carried out [4, 5]. In this manuscript, three typical winkled surfaces were delicately modulated and evaluated for comparison of tribological performance. 2. Experiments
