Abstract
Official abstract text for this publication.
An article has a surface topography for resisting bioadhesion of organisms and includes a base article having a surface. A composition of the surface includes a polymer. The surface has a topography comprising a pattern defined by a plurality of spaced apart features attached to or projected into the base article. The plurality of features each have at least one microscale dimension and at least one neighboring feature having a substantially different geometry. An average feature spacing between adjacent ones of the features is between 10 μm and 100 μm in at least a portion of the surface. The surface topography can be numerically represented using at least one sinusoidal function. In one embodiment, the surface can comprise a coating layer disposed on the base article.
First claim
Opening claim text (preview).
What is claimed is: 1. An article having a surface topography for resisting bio adhesion of organisms, comprising: a base article having a surface; a plurality of spaced apart features projected into said base surface, wherein each feature has a substantially different geometry than neighboring features, wherein neighboring patterns share a common feature; the plurality of spaced features arranged in a plurality of groupings wherein each grouping is identical with other groupi…
