PLASMA MODIFICATION OF POLYMER SURFACES

To avoid chemical destructions of macromolecules at the polymer surfac e and to obtain maximum improvement in adhesion properties the short-t ime exposure to plasma is a good choice. Enhanced quality of surface f unctionalization can be reached by chemical conversion of plasma intro duced functional groups. Additionally. molecular and supermolecular or ientations of the macromolecules and their re-arrangement by plasma ex posure influence the adhesion properties of polymers. Atmospheric pres sure plasma is generally suitable for high-speed surface modification of polymers.
