摘要: The effect of real contact geometry on adhesion was studied by measurement pull-off force, area, and perimeter fibrillar dimpled flat surfaces. structures, made polyvinylsiloxane, were brought in with a glass substrate. These experiments demonstrate that does not correlate the area. is found to be main geometrical factor governing adhesion. This results natural scaling finer structures exhibiting stronger
