Abstract

This Letter explores a method for the manufacture of solid microspheres of 30 mu m, from liquid droplets with nanosuspensions of 20 nm alumina in a microfluidic T-junction. These droplets are heated downstream where solidification takes place due to Temperature Induced Forming (TIF). TIF occurs as temperature sensitive alumina solubility leads to weakening electrostatic double-layer dispersing forces resulting in the formation of a solid structure. Manipulation of the flow characteristics and material properties of the continuous and dispersed fluids provides control of droplet production over a range of conditions and allows for a robust manufacturing facility capable of producing particles of various sizes.
