Abstract

The surface of various materials has been observed by optical reflection microscopy after exposure to the plasma generated in air at atmospheric pressure by a surface dielectric barrier discharge. The degradation of polymers (polymethyl methacrylate and polyvinyl chloride) has been characterized and differences appear between the two materials. A phenomenological interpretation is given. Borosilicate glass does not exhibit similar degradation for the same exposure.
