Assist. Prof. Chanthaset Assist. Prof. Yoshida【Greetings】 Based on the concept of “molecular technology” and“precise polymerization”, we create biomaterial, energy relatedmaterials, and environmentally friendly materials, using polymer
chemistry. We cooperate companies for actual application. We
contribute to society by development of human resources. In orderto achieve that, I do my best by frequent discussion with members
and by conveying approaches and challenging spirits. (Jan. 2024)

Control of Polymer StructureHigh Performance Polymer

Novel Functional Polymer

For the alternative of generalpolymers, new amphiphilic polymers
and natural polymers are utilized tocontrol mechanical strength orthermal properties.
For example, molecular weightand particle control by N–vinylamide,
flexible materials, resin altenative,
antifouling surfaces, and surface
control by chitin, cellulose, agaroseare designed and prepared.

Molecular technology concept
contribute to the creation of nextgeneration functional materials.
For example, water-harvesting,surface-covered, highly-stretching,
and water-retaining materials byfunctional hydrogels, thermal storageby nanofilm coating, and novel
functional materials bystereocomplex are created.
