Outline of Final Research Achievements

Quantz Crystal Resonator (QCR), which has high temporal resolution and high sensitivity measurements, is expected to form dynamic polymer brushes in the short time scales difficult to track with NR, so the dynamic polymer brush at the water / polymer interface Dynamic polymer brush formation was followed. Complex frequency change of quartz oscillation in water is sensitive to the viscosity of dynamic polymer brush and shows a property of sharply increasing from low concentration, so it was possible to measure the generation of dynamic polymer brush more sensitively. As a result, it was found that the time of changing life occurred in tens of seconds or less, and extremely fast restoration was carried out.
