Laboratory of Soft Crosslinked Materials (Gong Lab), Yamagata University

Welcome to Gong Laboratory！

Gong Laboratory is a new laboratory built in April 2015. Our current research interest is centered around the synthesis, 3D printing and applications of high-performance crystalline gels with multiple functionality as temperature-responsivity, shape memory, thermal energy (heat/cold) storage, etc. We are also chanlleging the synthesis and application of crystaline gel particle, crystalline gel fiber, crystalline gel nonwoven faric, thermalsensitive shrinkage film and crystalline gel micro-/nano-porous membrane.

Feel free to visit us or contact us if you are interested in our research or just our lab.
