Latest Patents

Weigand holds a patent for "Texturing polymer surfaces by transfer casting." This invention focuses on fabricating textured surfaces on polymers without altering their surface chemistries. The process involves exposing a surface of a fluorocarbon polymer to a beam of ions to create a texture. Subsequently, a polymer intended for surface roughening is cast over the textured surface. After curing, the cast polymer is peeled off, resulting in a surface that has a negative replica of the original texture. This microscopic surface texture enhances adhesive bonding, which is crucial in applications such as cardiovascular prostheses.
