Surface topographies for non-toxic bioadhesion control
First Claim
1. An article having a surface topography for resisting bioadhesion of organisms, comprising:
- a base article having a surface,wherein a composition of said surface comprises a polymer,wherein said surface has a topography comprising a plurality of repeated patterns, each pattern being defined by a plurality of spaced apart features attached to or projected into said base article, each feature being a single elongate structure extending longitudinally along the surface of the base article,said plurality of features each having at least one microscale dimension, each feature further having at least one neighboring feature having a substantially different geometry,wherein an average first feature spacing between adjacent ones of said features is between 10 μ
m and 100 μ
m in at least a portion of said surface,wherein said plurality of repeated patterns is separated by a pathway that is sinusoidal in shape.

Abstract
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.
