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
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
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.
