| Outline of Final Research Achievements |
The purpose of this research is to develop biomass-based thermoresponsive organogels contributing to the enhanced safety of lithium-ion batteries. Cellulose derivatives with diblock structure were coupled with two functional groups at the end of the molecules to afford several compounds with different substitution patterns and molecular weight. As the results, one compounds showed thermoresponsive aggregation behavior in an organic solvent. A compound with thermoresponsive gelation behavior was not found. However, possibilities to find such a compound remain in the future, based on the research strategy.
