Plasma Surface Modification of Polymers

A free white paper by Plasmatech, inc

Material selection of polymer components and disposables is determined by various factors such as physical/optical properties, cost, biocompatibility, etc. However, due to the hydrophobic (non-wetting) characteristics of many polymers, challenges can occur when bonding, coating or printing are required. Low pressure gas plasma is an environmentally- and user-friendly solution for modifying or functionalizing the surface of materials without changing bulk properties or appearance. While variable results can occur with so-called atmospheric plasma or corona treatments, low pressure plasma processes are absolutely repeatable since treatment occurs in a precisely controlled environment.
