Impact of sequential surface-modification of graphene oxide on ice nucleationElectronic supplementary information (ESI) available: This includes full experimental procedures and additional characterisation information. See DOI: 10.1039/c7cp03219f

Base-washed graphene-oxide which has been sequentially-modified by thiol-epoxy chemistry, results in materials with ice-nucleation activity. The role of hydro-philic/phobic grafts and polymers was evaluated with the most potent functioning at just 0.25 wt%. These 2-D hybrid materials may find use in...

Description
Summary:Base-washed graphene-oxide which has been sequentially-modified by thiol-epoxy chemistry, results in materials with ice-nucleation activity. The role of hydro-philic/phobic grafts and polymers was evaluated with the most potent functioning at just 0.25 wt%. These 2-D hybrid materials may find use in cryopreservation and fundamental studies on ice formation. Surface modified, base washed, graphene oxide is shown to be a potent ice nucleator.
