Organic Reaction Chemistry Lab
Machine-translated · View original
The lab studies organic reactions that break down stable plastics to give them new functions or return them to raw materials.
AboutAbout the lab
Taking on the precise breakdown and functionalization of underused resources
The Organic Reaction Chemistry Lab studies new molecular transformation reactions that convert the stable bonds of organic compounds and stable polymers.
From the perspective of precisely breaking down underused resources and adding functions to them, the lab develops technologies that contribute to the chemical recycling of plastics.
Under the University of Tsukuba's cooperative graduate school system, the lab operates at the Tsukuba Center of the National Institute of Advanced Industrial Science and Technology (AIST).
The lab can carry out joint research with a variety of AIST researchers, and AIST also has internal support programs for graduate students.
Key terms
- Chemical recycling
- A method of breaking down plastics and similar materials through chemical reactions, returning them to raw materials, and using them again
- Super engineering plastics
- High-performance resins with heat resistance and mechanical strength, such as PEEK and PPS
- Main chain
- The long connected series of bonds that forms the backbone of a polymer. Cleaving it splits the polymer into smaller molecules

ResearchResearch themes
The lab works on developing new molecular transformation reactions, from the perspective of precisely breaking down underused resources and adding functions to them. Building on methods for converting the stable bonds of organic compounds and stable polymers, it advances research toward real-world implementation.
*Illustrative imageMain-chain scission of super engineering plastics
Super engineering plastics such as PEEK and PPS are highly stable, which makes chemical recycling difficult. The lab develops reaction methods that cleave the main chain, and has succeeded in converting PEEK into monomers.
*Illustrative imageChemical decomposition of epoxy resins
The lab has succeeded in efficiently decomposing stable epoxy resins, used in adhesives and wind turbines among other things, and returning them to their raw-material compounds. The method also works on composites with carbon fiber or glass fiber, so the fiber materials can be recovered as well.
*Illustrative imageAdding functions to resin surfaces
Using its main-chain scission method for super engineering plastics, the lab has succeeded in cleaving only the main chains at the surface of insoluble PEEK, thereby adding functions to it.
