Laser Induced Surface Modification of Polymers

  • V. Malatesta
Conference paper

Abstract

It has been shown that irradiation with ultraviolet light results in surface modification of polymeric materials due mostly to photooxidation, photografting and/or photodegradation. Depending on the wavelength used one may anticipate that the more penetrating (wavelength higher than 200 nm) will cause degradation of the bulk structure, whereas surface and thin films dry modifications will require a wavelength that, because of the high-absorption cross-section of the polymer, penetrates to a smaller depth. This light (wavelength between 180 and 200 nm) is also characterized by the energy of the photons exceeding that of most covalent bonds and it is reasonable to expect a high probability of inducing bond breaking by irradiation.
