The use of DBD plasmas for treatment of PDMS surfaces and adhesion improvement

In this work we used an atmospheric pressure dielectric barrier discharge plasma to perform treatments of poly(dimethylsiloxane) (PDMS) surfaces in order to improve the adhesion between the samples. The results show that different conditions of plasma treatment can lead to a better adhesion between the PDMS surfaces. If the power delivered to the plasma is increased, the adhesion is better, but the best results are obtained if the vibrational temperature of the nitrogen molecules in the plasma is increased.
