Abstract
A material having a first surface and a second surface is disclosed. The first or second surface comprises a texture. The texture is defined by peaks and valleys such that the textured surface may have an Average Peak to Peak Distance in the range of about 3 mm to about 16 mm, an Average Height Differential of at least 1 mm, and a Surface Topography Index from about 0.1 to about 5. The material may comprise a surfactant.
Claims24
A macroscopically three-dimensional material comprising:
