Polymer Materials Science Lab
Machine-translated · View original
The lab creates functional materials from biologically derived polymers such as cellulose.
AboutAbout the lab
Creating new materials from polymers made by living organisms.
The Polymer Materials Science Lab studies how to use polymers made by living organisms (resource polymers), such as cellulose, as materials.
Its research aims to create functional materials, ranging from basic research on how molecules assemble to building structures with controlled assembly.
Using rheology, which examines how materials deform and flow, and structural observation by scattering methods, the lab investigates the relationship between the structure and the physical properties of materials.
On the lab's website, it is also introduced under the name "Resource Polymer Science Lab."
Key terms
- Biopolymers (resource polymers)
- Polymers produced by living organisms. They include cellulose, chitin, and protein fibers such as silk.
- Rheology
- The study of how materials deform and flow
- Hierarchical structure formation
- The process in which a single molecule becomes a fine fiber or molecular assembly, which then assembles further into a larger structure
ResearchResearch themes
Starting from a single molecule, resource polymers form fine fibers and molecular assemblies, which then assemble further into larger structures. With this hierarchical structure formation as its basic concept, the lab conducts research aimed at creating functional materials, ranging from basic research on how molecules assemble to building structures with controlled assembly states.
*Illustrative imageMaking functional materials from polysaccharide solutions
The lab dissolves polysaccharides, studies the properties of the resulting solutions, and makes materials such as fibers, films, and gels. It blends polysaccharides to bring out properties that a single polysaccharide cannot provide, and also develops materials using solvents that are gentle on people and the environment.
*Illustrative imageStructure and physical properties of fiber networks
The lab studies fiber networks used in paper, textiles, and fiber-reinforced plastics, examining the relationship between their structure and physical properties such as viscoelasticity, with the aim of improving processing. It also investigates how branching and cracks affect the properties of the networks.
*Illustrative imageBuilding fundamental theory for fibrous materials
Because a comprehensive theory of fibrous materials is still lacking, the lab aims to build a fundamental theory that connects each level of the hierarchy: hydrogen bonding, twisting of polymer chains, entanglement of polymers, and entanglement of fibers.
