Relation between surface energy and adhesive capability of polymers using the example of polypropylene and polybutylene terephthalate and their modification by the use of low-pressure plasma technology

Central point of the dissertation is the relation between surface energy and adhesive capability of polymers. The investigation of the attainable adhesive strength using the example of polypropylene and polybutylene terephthalate. For reproducible modification of the adherend surfaces the low-pressure plasma technology is systematically used and developed and also a new optimization strategy for the rapid discovery of successful process parameters is described.

The results of the work carried out in the light of the described in the literature models for interpretation of adhesion.

For the studied adhesive/substrate systems a correlation between surface energy - in particular the polarity - and the bond strength is detected. This correlation allows scale-up of the laboratory results in production processes.
