Covalently functionalized hexagonal boron nitride nanosheets by nitrene addition
SATTI, AMRO; COLEMAN, JONATHAN NESBIT; GOUNKO, IOURI; MAY, PETER; O'NEILL, ARLENE; NICOLOSI, VALERIA (Wiley, 2012)Exfoliated h-BN nanosheets were covalently functionalized via a one-step nitrene addition using azide precursor molecules. Functionalized h-BN nanosheets were found to exhibit markedly enhanced dispersability relative to ... -
Graphene-ionic liquid electrolytes for dye sensitised solar cells
BRENNAN, LORCAN; SATTI, AMRO; BARWICH, SEBASTIAN; GOUNKO, IOURI (2013)In this work two dimensional graphene flakes were used to prepare new electrolytes for dye sensitized solar cells (DSSCs). Small amounts (up to 3 wt%) of graphene nanoflakes were suspended into the ionic liquid (IL) ... -
Improvement of Mechanical Properties of Graphene Oxide / Poly(allylamine) Composites by Chemical Crosslinking
SATTI, AMRO; GOUNKO, IOURI (2010)Graphite oxide was prepared by oxidation of graphite using the Hummers method, and its ultrasonication in water yielded dispersed graphene oxide (GO) sheets. These sheets were then crosslinked with a water soluble polymer, ... -
Oxygen radical functionalization of boron nitride nanosheets
MAY, PETER; COLEMAN, JONATHAN; MCGOVERN, IGNATIUS; GOUNKO, IOURI; SATTI, AMRO (2012)The covalent chemical functionalization of exfoliated hexagonal boron-nitride nanosheets (BNNSs) is achieved by the solution phase oxygen radical functionalization of boron atoms in the h-BN lattice. This involves a two-step ...
