Research Interests include polymer physics, and polymer properties especially about polymer crystal and crystallization processes. He has focused on the so-called shish-kebab formation processes by in-situ synchrotron radiation X-ray scattering and neutron scattering techniques . Furthermore, he developed new type optical microscope with high speed camera, then succeeded the micron-scaled fibril structure formation and various lamellar crystal growth process with in-situ X-ray scattering . Then he collaborated computer simulation about shish-kebab formation process with Prof Hu at Nanjing University . He collaborated a lot of industrial companies. He and his students studied about crystal morphology about polypropylene reinforced with cellulose nanofibers, membrane for polymer electrolyte fuel cells, temperature sensitive adhesives and ionomers. Furthermore, he has interested in complicated structure of rat bones (hybrd materials), starch and cellulose fibers. He also interested in correlation between morphology and polymer properties, such as gas barrier (or gas permeability) properties and some special gels.
