| Research Abstract |
This research aims to develop a new exfoliation method that relies on phase-change of water and can exfoliate layered materials to obtain nanosheets. The research also aims to reconstruct the resultant nanosheets into functional materials via phase-change of water. (1) We have successfully exfoliated graphite oxide in water to obtain dispersed graphene oxide nanosheets with high efficiency via rapid freezing-thawing cycle of the solution.(2) We have also succeeded in the reconstruction of the resultant graphene oxide into a 3D macroporous monolith using ice crystals as the template.
