MICROSTRUCTURED POLYMERIC SUBSTRATE

摘要

A method of preparing a polymeric substrate having a surface which includes a plurality of microaberrations (5a, 5b) is provided. A polymeric material (1) in a flowable state is contacted with a resilient surface (9) to form microaberrations (5a, 5b) which are inverted replicas of microaberrations (4a, 4b) present on the resilient surface. A cleaning article and a slip control material which include the microstructured polymeric substrate are also provided.
