Using a vacuum ultraviolet excimer lamp! Examining how the chemical structure of polyvinyl alcohol changes.
Vacuum ultraviolet (VUV) light, due to its short wavelength and high photon energy, can break molecular bonds through non-thermal processes, leading to advancements in applications such as cleaning, microfabrication, and surface modification. In this document, after spin-coating a PVA aqueous solution onto a gold-coated substrate, a heating treatment was performed to create a film, which was then irradiated with a xenon excimer lamp (172 nm) under a nitrogen or dry air atmosphere. Using an infrared spectrometer and X-ray photoelectron spectroscopy, we observed changes in the chemical state of the PVA film due to VUV irradiation.
