Abstract

In this paper, a novel turbulent microfluidic emulsifier is shown. The emulsifier is fabricated by commonly used poly(dimethylsiloxane) (PDMS) and glass substrates bonded by a strongly cross-linked nano-adhesve layer deposited via initiated chemical vapor deposition (iCVD). Unlike conventional microfluidic devices, the turbulent microfluidic emulsifier is able to operate at turbulent regime (Re ∼ 4423) allowing emulsification of Si oil at a rate of ∼106 Hz with average emulsion size of ∼4.44 ± 2.07 μm. The turbulent kinetic energy of the device is ∼8 × 105 W/kg, which is almost two orders of magnitude higher than that of macro-scale agitated mixer (∼104 W/kg).
