Yet, their poor dispersibility to any solvents thermal, and mechanical properties. Yet, their poor has posed problems for chemical applications. Having succeeded in dispersibility to any solvents has posed problems for chemical applications. Having succeeded in chemical chemical reactions of CNT over 20 years ago, we can offer various reactions of CNT over 20 years ago, we can offer various techniques to disperse nano-carbons in liquids and polymers.techniques to disperse nano-carbons in liquids and polymers.Recently, we developed Twilight Fluorescence Microscopy which is Recently, we developed Twilight Fluorescence Microscopy capable of imaging single-layer graphene floating freely in liquids. which is capable of imaging single-layer graphene floating Not only morphology, but the layer number can be directly measured freely in liquids. Not only morphology, but the layer number as well. It is also possible to observe a modification in electronic can be directly measured as well. It is also possible to structures of graphene through a change in the image contrast.observe a modification in electronic structures of graphene through a change in the image contrast.Graphene oxide exhibits photoluminescence in the visible region by Graphene oxide exhibits photoluminescence in the visible UV excitation. Its intensity, however, is too low to be useful for region by UV excitation. Its intensity, however, is too low to practical applications. Recently, we have found new chemical be useful for practical applications. Recently, we have found phenomena that enhance PL significantly.

Especially, we are processes: melting, flowing, and solidifying. Especially, we are focusing on the melt state behaviors, since the viscoelastic focusing on the melt state behaviors, since the viscoelastic response plays an important role in polymer processing. We have studied not only the linear viscoelasticity but also the nonlinear response plays an important role in polymer processing. We behaviors, which can be related to the practical applications such have studied not only the linear viscoelasticity but also the as foaming, film casting, film blowing, blow molding, nonlinear behaviors, which can be related to the practical electrospinning, etc. In order to realize desired shapes, our goals applications such as foaming, film casting, film blowing, blow are to design the materials which have appropriate rheological molding, electrospinning, etc. In order to realize desired shapes, behaviors, and to optimize processing methods and conditions.our goals are to design the materials which have appropriate rheological behaviors, and to optimize processing methods and Appealing point：We have carried out the researches on the correlation between conditions.polymer rheology and the processing from academic and practical points.
