BIOCOMPATIBLE PLASTICS, PROCESS FOR PRODUCING THE SAME AND FIELDS OF USE

摘要

Biocompatible plastics, a process for producing the same and their fields of use are disclosed. The plastics are provided with surface layers with fibrous surface structures produced in the elastic-viscous or plastic state from originally smooth surface layers. Both natural materials and modified materials may be used as starting materials to generate these surface layers. The surface layer is provided with fibers by pressing a matrix into the plasticised surface layer of the plastic material then by peeling off the matrix from the cooled plastic material. The thus generated surfaces favour the adherence of cells or tissues to the plastics. This is particularly valid for plastics with low wettability, such as the polyolefins. This process must be further developed and adapted for the special requirements of medical applications. The use of prepared matrices allows special, biocompatibility-favourable substances to be introduced into the surface layer of the plastic material.
