Paper Abstract

The good chemical resistivity of some polymers generally is connected with poor adhesive properties of the material. Because of this it is difficult to adhere, paint or coat them. This makes a pretreatment procedure necessary. Nowadays mechanical, wet-chemical, or plasma treatments of the workpieces are applied. Most of these methods, however, are limited in practice, for example because they require specific treatment conditions. This is the reason why improvement of the existing technologies and look-out for alternative methods are subjects of current research. One relative new way to change the surface properties of polymers is the use of excimer lasers. In the present paper recent results are presented concerning the interaction of UV-laser radiation with polymers. The emphasis here is the photolytical modification and activation of their surface. On the basis of a proper activation, for example, a significant enhancement of the adhesive bond strength between a polymer and an adhesive (in this case epoxy resin on polypropylene foil) has been achieved.
