Abstract

See full text

A structured surface, which includes a thermoplastic backing sheet and a first upstanding element, is disclosed. The first upstanding element includes multiple, spaced-apart posts and a single cap at the distal ends of the multiple, spaced-apart posts. The structured surface furthermore typically includes a plurality of spaced-apart, upstanding posts with caps on their distal ends, where the ratio of the caps to the posts is less than one-to-one. Also disclosed is a method of making a structured surface. The method includes providing a thermoplastic backing sheet with a plurality of spaced-apart, upstanding posts; and deforming the distal ends to form caps on at least some of the spaced-apart, upstanding posts. At least some of the caps upon forming touch at least one adjacent cap to form a conjoined cap at the distal ends of multiple posts.
