Korea Advanced Institute of Science and Technology (KAIST) announced on the 18th that the special issue “Graphene Oxide Liquid Crystal” of "Particle and Particle Systems Characterization", which was edited by professor Sang Ouk Kim, was published online.


The Particle and Particle Systems Characterization is published by Wiley-VCH, an international SCI journal covering particle synthesis and application. Graphene Oxide is attracting enormous attention as a material closest to commercialization of graphene because it can be manufactured at low cost from natural graphite.


Especially, when liquid crystal of graphene oxide is used, it is expected that they can play a role in making highly functional materials because alignment direction of graphene oxide can be easily adjusted to nano level.


Professor Kim's research team discovered that graphene oxide has liquid crystals it is dispersed in liquid for the first time in 2011. By recognizing this discovery, he led the editing of this special issue.

In this special issue, twenty world-renowned scholars from related fields participated in the research and this issue covers key issues on this field: development of high performance graphene oxide liquid crystal fiber fabrication, three dimensional structure fabrication using liquid crystal, and graphene oxide liquid crystal based catalyst. Among them, Professor Kim's team introduced a catalytic study of graphene oxide liquid crystal fibers.


The researchers fabricated a fiber-type catalyst by electrodeposition of amorphous molybdenum sulfide over graphene liquid crystal fibers. With this technology, the catalyst was uniformly deposited on the surface wrinkles generated during the drying process of the graphene fibers and the catalyst was able to contain much more catalyst than the two-dimensional substrate. Thus, hydrogen evolution catalytic performance and stability of the hybrid fiber was excellent.


"The research and industrial potential of graphene oxide liquid crystals is endless," Kim said. "The value of graphene-based new materials will further increase as a customized material suitable for the fourth industrial revolution."


Meanwhile, Professor Kim was invited along with prominent scholars such as Nobel Prize winner in Graphene Week of Europe's largest graphene association held in Greece on 25th of last month, and announced the results of related research.
