About Us：We
study & develop organic polymer materials
that response to stimuli, and that
adapt to environmental conditions. We use both simple molecular designs and
green reactions as much as we can.
We also research degradation behavior of
organic polymer materials, believing to solve problems about plastic
wastes.
【Students, please join us!】
We
welcome ALL students who will start working, or who
will continue studying in a university or the advanced engineering course,
after graduation.
Check-list is shown here! How many “Yes” do you have?
1.□ I’m interested in environmental problems,（※） 2.□ organic chemistry, 3.□ and/or polymer chemistry.
4.□ I want to synthesize novel organic compounds, 5.□ and/or evaluate properties of them.
6.□ Academic activities 7.□ and/or chemical engineering
approaches are attractive for me.
※ We believe that our study & research contributes to solve
environmental problems, especially plastic-waste problems.

Study & Research：
(1) Organic polymer materials that response to stimuli
Photo-adhesive materials “dismantled”
with gentle heating and small stress …Adhesives
have contributed to lightening of industrial products. Especially,
photo-adhesives play an important role in industry, because they enable to
adhere in a short time, without heat, at a local area where UV-light is
irradiated. However, dismantlement of the adhesive layer is quite difficult,
which disturbs re-use & re-cycle activities. To overcome this situation, we
have proposed a novel dismantlable photo-adhesive material utilizing exchange
reactions of disulfide (SS) bonds. Using the adhesive at room temperature, SS
bonds in the adhesive layer work as covalent bond, leading to keep the adhesive
strength high. On the other hand, heating at 100 degree C after use, SS bonds exchange
dynamically, resulting in dismantlement of the adhesive layer with small
stress. Adhesive residues on the adherents would be used for the re-adhesion
process with gentle heating.
Adsorbents “colored” by
adding heavy-metal cations …Removal technology
of pollutants from water & air is indispensable for our healthful lives or
sustainable society in future. We fabricate UV-cured materials including SS
bonds with a high density, and evaluate their adsorbing property toward
pollutants. Strong interaction between SS bonds and heavy-metal cations (or
harmful proteins) will be expected on the material surface. Coloring or
opacification of the materials is observed in the adsorbing process, which
would be applied to a pollutant-sensor as well as an adsorbent.
(2) Organic polymer materials that adapt to environmental conditions
Photo-adhesive materials “adapting with equilibrium reactions” toward any surfaces …The importance
of (photo-)adhesives is mentioned above. Furthermore, industrial products are
now manufactured in combination of various kinds of materials, and adhesives
for dissimilar materials have been desired and developed. We have proposed to
introducing chemical structures that cause equilibrium reactions (e.g. 2-mercaptopyridyl group), into side
chains of polymers in the adhesive layer. These chemical structures are changed
by their chemical environment such as polarity, which would lead to maximize
the interaction between an adherent and the adhesive layer. As a result, high
adhesive strength would be obtained with any adherents.
(3) Degradation
behavior of organic polymer materials
Research on degradation factors of
plastic wastes …Recently, micro-plastics (MPs) have paid
much attention as one of disturbing pollutants. Plastic wastes are exposed to
stimuli such as light, heat & external force etc. in natural environment,
resulting in deterioration & fragmentation of the material to generate MPs.
However, details of the processes are not clear. We evaluate both mechanical
& chemical properties of plastic products & wastes, to consider the
main factor & its action mechanism for MPs’
generation.
