N2 - In this study, the core/shell structured microcapsules encapsulating oily magnetic fluid (OMF) with hexanediol diacrylate (HDDA) as the shell were fabricated with an oil/oil/water double emulsion template in needle-based microfluidic multiphase system. A computational model employing the volume of fluid-continuum surface force (VOF-CSF) method was developed to investigate the key parameters influencing the formation of double emulsion. Using this model, the effects of the three-phase flow rate on the size and morphology of the microcapsules were extensively studied and it is found that changes in flow rate significantly impact the formation and characteristics of the microcapsules. Based on simulation experiments, the magnetic responsiveness of the resulting OMF-HDDA microcapsules were demonstrated. This study shows the effectiveness of the double emulsion droplet template strategy in magnetic microcapsule fabrication and envisions the potential applications of OMF-HDDA microcapsules.
