| Overview of Our Research Topics | |||||||
| We are involved in research and development of highly functional polymers from knowledge of high ?order 3D structures and electronic structures of fluoropolymers and fully aromatic polymers. Methods we use are optical properties measurements, spectroscopic methods and quantum computational calculations analysis. In short, |

| "Development of New Polymer Spectroscopy and Functionalization of Polyimides and Fluoropolymers" |
|||||||
| Aromatic polymers including polyimides are known to have interesting thermal, electrical, and optical properties and makes up a proportion of highly functional polymers. Also fluoropolymers are highly interesting materials due to their electronic and optical properties. Currently we are focusing on thermally stable polymers (polyimides), solid state structural analysis of fluoropolymers and investigation of optical properties, and development of optical/thermal polyimides. Below are some of our past researches. Please visit our laboratory if you are interested. |
