Graphene Oxide Liquid Crystals

摘要

Liquid crystal is the mesomorphic ordered state of anisotropic particles that bears liquid-like fluidity as well as crystal-like ordering.'11 Along with the recent enormous interest in carbon materials, carbon-based liquid crystals hold great promise for high-performance carbon material synthesis or device operation. Liquid-crystalline processing of carbon nanotubes, as well as mesophase pitch, has been employed for highly oriented carbon fiber spinning. Discotic liquid crystals of synthetic graphitic hydrocarbons arc promising components for advanced electronics and optoelectronics. Herein, graphene oxide liquid crystals are introduced as a versatile new class of carbon-based liquid crystals.
