About Us
Nagano Laboratory at Rikkyo University has started in April 2020. The first master students completed their studies and graduated last fiscal year. The young leader, prof. Ishizaki joined our lab in 2022. We focus on electrical measurments for polymer assmenblys. 6 master's students, 7 fourth-year students and 5 third-year students conduct our research now. They are working hard and reliably to carry out their research steadily.
As typified by LCDs, our goals are to create new material functions emergent by dynamically designing the nanostructures and molecular orientations of soft materials such as LCs and polymers. Now, we are developing the molecular orientational functions of LC polymer materials, such as photo-reorientation of LC polymers and block copolymers, photoaligned directed self-assembled lithography materials, photoaligned ion-conductive polymers, the thermal conductivity of liquid crystalline polymers.
