Abstract
Usefulness of the application of quartz crystal microbalance (QCM) on the atomic oxygen-induced erosion study of polymeric material is presented. Polyimide film was spin-coated on an Au electrode of QCM sensor crystals and mass change of the polymer film was measured from the frequency shift of the QCM during atomic oxygen beam exposures. Extremely high resolution in mass of QCM measurement is suitable for in-situ mass loss measurement of polymers during AO beam exposure even though its dynamic range of mass measurement is narrow. In this presentation, we are reporting our recent research results on atomic oxygen-induced polymer degradation using QCM; (1) non-linear mass loss phenomenon during atomic oxygen-induced erosion, (2) temperature dependence of polymer erosion due to hyperthermal atomic oxygen beam exposure, and (3) comparison of atomic oxygen flux measurements using Ag-QCM and Kapton witness sample.
