The lab creates energy and environmental materials from nanomaterials and organic materials.
AboutAbout the lab
Efficient transport pathways for ions, water, and electrons.
The Matsumoto Lab studies energy and environmental materials that take advantage of the characteristics of nanomaterials and organic materials.
One-dimensional nanomaterials such as nanofibers and nanotubes form interconnected networks.
These networks act as pathways for electrons, ions, and water molecules, and are expected to be applied to batteries, fuel cells, and separation membranes.
The lab makes materials using diverse methods, from molecular synthesis to self-assembly, microfabrication, and compositing, and clarifies how their functions arise.
Key terms
- Nanofiber
- A thin, long fiber whose diameter is only on the order of nanometers
- Self-assembly
- A phenomenon in which molecules or particles gather on their own and form a definite shape or arrangement
- Synchrotron radiation
- Very bright X-rays emitted when electrons accelerated to nearly the speed of light are bent

ResearchResearch themes
Among nanomaterials, one-dimensional ones such as nanofibers and nanotubes attract interest for their shape and distinctive functions. The Matsumoto Lab uses the dense networks they form as transport pathways for electrons, ions, and water molecules, aiming at applications in energy and environmental devices.
*Illustrative imageMaking Nanofibers
Nanofibers, which are fibers made as thin as possible, change in function depending on the design of their diameter, surface properties, and internal structure. The lab works to understand the spinning process, which uses high voltage or high-pressure air, and controls the diameter and internal structure.
*Illustrative imageMaterials That Support Batteries
Films made by stacking nanofibers like nonwoven fabric become porous materials with interconnected pores. The lab is advancing applications to secondary batteries with metal anodes, electrolyte membranes for fuel cells, and porous electrode materials.
*Illustrative imageMembranes That Separate Water and Other Substances
The ultimate design principle for high-performance separation membranes is to mimic biological cell membranes. The lab makes composite membranes of vertically aligned carbon nanotubes and polymers and studies how substances pass through the hydrophobic nanoscale space.
*Illustrative imageConfirming Structure with X-rays
Designing material functions requires precise structural analysis and, based on it, an understanding of the mechanisms behind physical properties. Using synchrotron X-ray scattering, the lab examines in detail the structures of nanofibers, polymer membranes, and polymer thin films.
