Polymer Chemistry, Environmental materials

Dr. Chikara Tsutsumi received the Doctor of Engineering (2004) in polymer chemistry from Hiroshima University, Japan. He is a Professor at the Department of Applied Chemistry and Biotechnology in National Institute of Technology, Niihama College (NIT,Niihama College). He has been studying synthesis and applied research of environment-adaptable degradable polymer degraded in soil, compost, ponds and the sea. Practical use in the society of the degradable polymer is aimed at, the Sustainable Development Goals (SDGs) is tackled for solutions to environmental problems. He previously attempted to impregnate biodegradable polymer such as poly(L-LA) or its copolymers with useful organic compounds using supercritical carbon dioxide as the solvent. He has recently attempted to fabricate biodegradable copolyester films that gradually adopt UV shielding characteristics based on changes in crystallinity resulting from the effects of temperature and humidity.
