| Outline of Final Research Achievements |
A rheo-optical characterization technique based on the combination of near-infrared (NIR) spectroscopy and mechanical analysis was investigated to measure strain-dependent NIR spectra as well as tensile stress of polymer samples. Sets of NIR spectra were collected by using an acousto-optic tunable filter (AOTF) NIR spectrometer coupled with a tensile testing machine as an excitation device. The utilization of the AOTF, which is a wavelength tunable filter based on high-frequency transducer, offers a clear advantage over the conventional grating-monochromator or interferometer based approach in terms of high speed data acquisition, especially when the variation of the system occurs in relatively short time scale. Consequently, side-by-side comparison between the spectral feature and the corresponding stress or strain behavior provides the key information on the evolution of supermolecular structure essentially governing the macroscopic deformation of the polymers.
