Using a cross-flow microfluidic chip for monodisperse UV-photopolymerised microparticles

摘要

In this work, the flow characteristics of immiscible liquids on the microscale are exploited. Two solutions, which are immiscible were prepared with one being mineral oil and the other a mixture of 4-hydroxybutyl acrylate, acrylic acid, ethylene glycol dimethacrylate and a Type I photoinitiator. The chemical reactor was in the form of a crucifix (one long channel with two shorter channels intersecting the long channel at right angles a third of the way along the long channel) with the microchannels having a width 800 um and a depth of 1.5 mm.
