Abstract: 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 fishscaleshaped GONs resulting in selfassembly quasiordered microscale morphologies.
