In the evaluation of the process different characterization techniques have been used. An aging is applied to the specimens by a low pressure plasma treatment. In this study, the gas used in plasma state is the air. To optimize the outcome of the treatment the power and the time are varied in order to get a more exhaustive study. The goal of this treatment is to increase the surface energy of the polymer in the treated surface and thus achieve and optimization of its function in later uses.
The study of the variation in the surface energy for the treated polymers in the plasma chamber will be make measuring the contact angle of some drops in the surface of the polymers. Using this contact angles we are able to obtain the surface energy of the polymers, that lately will report an obtective conclusions of the study.
