Abstract
Methods for creating nanostructured surface features on polymers and polymer composites involve application of low pressure during curing of solid polymer material from a solvent solution. The resulting nanoscale surface features significantly decrease bacterial growth on the surface. Polymer materials having the nanoscale structuring can be used in implantable medical devices to inhibit bacterial growth and infection.
