Abstract

The emulsion droplets with limited control over interfacial properties, or the formation of polymerized droplets, the microfluidic approach enables the preparation of monodisperse emulsion droplets with sizes larger than approximately 2 micrometer. The versatile method based on templating polyelectrolyte multilayer (PEM)capsules formed by the layer-by-layer adsorption of PEs on sacrificial particles, to produce a range of emulsions of a predetermined size and surface chemistry. The APTS (3- aminopropyltriethoxysilane) functionalized silica particles are coated with PEMs, and the coated particles are exposed to hydrofluoric acid (HF) to etch the silica core, resulting in the formation of PEM ..
