Outline of Final Research Achievements

Nano-palpation atomic force microscope, which had been originally developed by the applicant, was now improved to perform nanoscopic viscoelastic measurement. The instrument was incorporated with wide-frequency sweep capability as well as temperature control, which enabled us to precisely determine the shift factor that is most important parameter in time-temperature superposition principle. The research on filled rubber system was conducted to elucidate the powerfulness of the method, which revealed the loss tangent peak had a certain shift to lower frequency at the filler-rubber interface. Such information is indispensable in R&D of tire industry.
