摘要

In this Technical Brief, we report on preliminary results of an experimental investigation of quenching of aqueous colloidal suspensions with graphene oxide nanosheets (GONs).Extremely dilute suspensions with only 0.0001% and 0.0002% (in mass fraction) of GONs were studied and their critical heat fluxes (CHF) during quenching were determined to increase markedly by 13.2% and 25.0%, respectively, as compared to that of pure water. Such efficient CHF enhancement was interpreted to be caused primarily by the improved wettability of the quenched surfaces, due to deposition of the fish-scale-shaped GONs resulting in self-assembly quasi-ordered microscale morphologies.
