Abstract
A method for preparing microcapsules using a droplet-based microfluidic chip. Monodisperse microcapsules, which are hollow or can be loaded with a desired material, are prepared using a droplet-based microfluidic chip through the movement of a monomer molecule from the inside of droplets to the interface of droplets, the diffusion of a photoinitiator to the interface of droplets, and the suppression of radical activity by oxygen in droplets. The method involves the use of a simple microfluidic channel and selectively photopolymerizing the shell of the droplets without needing the use of a chemically treated microfluidic channel or a complex microfluidic channel.
