As
a wonder material, graphene has offered a new platform for various applications
in materials science and engineering. Chemical modification of graphene is a
key step to introduce new and desirable functionality which combines with the
intrinsic merits of graphene in optical and electronic properties. While
pristine graphene is largely chemically inert, chemically exfoliated graphene
oxide (GO), as a building-up starting material, possess the advantages
including low-cost production and facile post-functionalization with
wet-chemical methods. Both covalent and non-covalent methods are applicable to
modifications of GO nanosheets [1]. To date, many studies have shown that GO
and its reduced form, reduced graphene oxide (rGO), can be chemically modified
through different types of chemical bonding but less to none using phosphorous
bonding that could offer unique advantages such as tunable mechanical property [2].
In this work, we have systematically performed the studies on the synthesis and
structural charaterization of phosphate attached GO (P-GO) or/and rGO
nanosheets (P-rGO) [3], with the aim to generate mechanically strong as well as
super-hydrophilic nanocomposites. Some key results will form a poster presented
in this conference.

Susanne
H. Jensen is currently a master student under supervision of associate
professor Qijin Chi, affiliated with the Nanochemistry group at the Department
of Chemistry, Technical University of Denmark, and will fulfill her master
degree in August 2015. She has studied applied chemistry and chemical
engineering through the past 6 years. Susanne is interested in the research that
can produce new materials for potential applications in chemical and mechanical
engineering, with particularly keen to polymer-graphene nanocomposites. The
poster presented in Carbonhagen 6 is the key part of the results obtained in her
master thesis project. |
