２）超臨界流体を利用した発泡体や多孔材料の創製
３）結晶構造制御や一軸・二軸延伸による高性能化
４）小角X線散乱、広角X線回折、光散乱による構造解析
５）応力―複屈折測定や誘電緩和測定などによる分子運動の評価

Summary
We design the high performance polymers by controlling the superstructure with various shapes and sizes using various methods such as blending, crystallization, elongation, and supercritical fluids.
1) High performance polymer blends
2) Design of polymeric foams and porous materials by using supercritical fluids
3) Improvement of physical properties by crystallization, or uniaxial and biaxial elongation
4) Analysis of superstructure by small angle x-ray scattering, wide angle x-ray diffraction, and light scattering
5) Estimation of molecular motion by stress-birefringence measurement and dielectric spectroscopy
