Polymer Materials Science Lab
Machine-translated · View original
A lab that improves material performance by studying the structures that polymers form on their own.
AboutAbout the lab
Even the same material performs differently depending on its internal structure
The Polymer Materials Science Lab (Takenaka Lab) studies how polymers create structures on their own (self-assembly) and how to control them.
In addition to tires, organic glass, and electronic device materials, the lab studies recycled polymer materials and bio-based polymers. It examines the self-assembled structures that determine their performance from multiple angles, using synchrotron X-ray scattering, electron microscopy, and X-ray CT.
Key terms
- Self-assembly
- A phenomenon in which atoms and molecules arrange themselves spontaneously and form a structure
- Bio-based polymers
- Polymers made from biological resources such as plants
- SPring-8
- A large experimental facility in Hyogo Prefecture that uses intense synchrotron radiation (X-rays)
ResearchResearch themes
The lab studies how to understand and control the structures that polymers create on their own (self-assembly).
*Illustrative imageUnderstanding and controlling self-assembly
The stiffness, strength, and transparency of a polymer vary greatly depending on the structure formed when atoms and molecules arrange themselves spontaneously. The lab aims to understand and control the structures that polymers create on their own.
*Illustrative imageImproving the performance of recycled and bio-based materials
The lab works to clarify, from a structural viewpoint, why performance drops in recycled and bio-based materials, and to use that understanding to improve their performance.
*Illustrative imageVisualizing hierarchical structures
The lab visualizes the hierarchical structures of polymers, from the nanometer to the micrometer scale, from multiple angles by combining X-ray scattering using synchrotron radiation such as SPring-8, electron microscopy, and X-ray CT.
