Abstract

In this presentation, potential of the terahertz (THz) waves as a new tool for polymer science will be discussed. In the first part, THz spectroscopy of polymers will be presented. Absorption spectra of polymer reflect their higher-order conformation which provides information about polymer crystallization, degradation and water adsorption. We have succeeded to develop method for the assignment of low-frequency vibrational modes of polymers and obtained information of their higher-order conformations. By the temperature dependent THz spectra, the change of the hydrogen-bond interaction and the structure of the polymers during the phase transition were observed.
