研究内容

Catalyst designs for polyolefins

In spite of being at the top of the world polymer production, researches in polyolefins have been said as a mature area as the progresses have been made by the refinement of the existing materials. Meanwhile, growing concerns in environment and sustainability have brought polyolefins back to a spotlight due to their high life-cycle eco-efficiency, e.g., low energy consumption in the production process, recyclability for second-life use, etc. Likewise, the development of highly functional polyolefin materials with desired properties becomes essential for sustainable growth and to meet the requirement in today’s advanced applications. Our lab aims to develop methodology and knowledge to access a new class of polyolefins with tailored properties by synergistic catalyst and polymer design.

Hierarchically structured porous materials

High performance and multifunctionality of solid materials often arise from multicomponent and multidimensionality of structural features. The hierarchy of materials on porosity is also one of the keys for high material performance in many applications. We aim to develop a method for controlling the structure and morphology of hierarchically structured porous materials for catalysis and adsorption applications.
