Deformation of droplets with magnetic nanoparticles in a rotating magnetic field

Abstract

This paper investigates the change in contact angle of droplets of fluid containing dispersed nanoparticles (nanofluid) stabilized in oleic acid and ethanol placed in a rotating magnetic field. Paramagnetic nanoparticles with an average size 100 nm were injected into the droplets and situated on the magnetic stirrer. Experimental measurements of the contact angle of nanofluid droplets cast on PDMS substrates show that the contact angle depends on nanoparticle concentration and the magnets rotation speed. These findings contribute to understanding the role of functionalized nanoparticles in surface wettability.
