Abstract
A coated surface for resisting or enhancing bioadhesion includes at least one patterned polymer including coating layer having a plurality of features attached to or projected into a base surface. The features each have at least one microscale (<1 mm) dimension and have at least one neighboring feature having a substantially different geometry. The patterned coating layer preferably provides an average roughness factor (R) of from 4 to 50. The coating layer resists or enhances bioadhesion as compared to the base surface.
Claims18
A coated surface topography for resisting bioadhesion, comprising:
- at least one coating layer that comprises a polymer, said coating layer having a pattern defined by a plurality of spaced apart features attached to or projected into a base surface, said plurality of features each having at least one microscale dimension and having at least one neighboring feature having a substantially different geometry, wherein an average spacing between adjacent ones of said features is between 0.5 and 5 μm in at least a portion of said coating layer, said coating layer resisting bioadhesion as compared to said base surface.
An article having a surface coating with topography for controlling bioadhesion, comprising:
- a base surface;
- and
- at least one coating layer that comprises a polymer, said coating layer having a pattern defined by a plurality of spaced apart features attached to or projected into a base surface, said plurality of features each having at least one microscale dimension and having at least one neighboring feature having a substantially different geometry, wherein an average spacing between adjacent ones of said features is between 0.5 and 5 μm in at least a portion of said coating layer, said coating layer resisting bioadhesion as compared to said base surface.
