The objective of this study is to understand the crystallization behavior using polydimethylsiloxane (PDMS) - based microfluidic devices within droplets. First, PDMS based microfluidic droplet making device was designed and fabricated to produce uniform emulsion. To achieve complete crystallization within the droplet, several parameters were varied, especially crystallization before exiting device and without breaching fluid/fluid interface to form uniform crystals. Those parameters include solution concentration, flow rates and temperature to understand their influence on crystallization kinetics. For the initial optimization, an aqueous sodium acetate solution was used, though differing pressures within the device made it extremely difficult to control when crystallization occured without changing concentrations and controlling other parameters. By changing concentration, temperature, and water of hydration in materials, better results were achieved. The presentation will discuss influence of these parameters on crystallization in microfluidic droplets.
