Effect of Ultrasonication Duration Onstability of Graphite Nanofluids

Abstract
The effect of ultrasonic duration on the stability of Graphite-Ethylene glycol (EG) and water based nanofluid is reported in this paper. Accordingly, ultrasonication duration of 2 hour, 3 hour and 4 hour was selected for water based nanofluid and ultrasonication duration of 2 hour and 4 hour was selected to prepare EG based nanofluid. Zeta potential analysis for these prepared nanofluids was carried out. UV-vis spectroscopy analysis was performed for EG based nanofluid prepared by ultrasonicating for 3 hours. From the analysis it was observed that the prepared nanofluid have good stability and it increases with increasing ultrasonication duration. Keywords - Nanofluid, ultrasonication, graphite, ethylene glycol.
