| Research Abstract |
The Xe sorption amounts and ^<129>Xe NMR spectra of many polymer solid materials under various pressures of Xe were measured. It was established that the micro pore of 0.1 nm order can be surely estimated by analyses of these observed data, although the electron microscopic observations for the pore were impossible. In addition, it was also demonstrated that the diffusion behaviors of the gases in polymer materials were evaluated in detail by the some new proposed NMR techniques. These outcomes are very important for the development of novel gas separation and barrier polymeric materials.
