Amphiphilic Janus particles can be used in various fields such as drug delivery carriers, optical lenses, and Pickering emulsions. The behavior of these Janus particles can be confirmed through an image by coloring a fluorescent dye. Physically adsorbed dye has difficulty in image confirmation due to desorption and solvent contamination. In this study, amphiphilic Janus particles composed of poly(styrene-co-vinyl alcohol) and poly(tetradecyl acrylate) were synthesized. In order to confirm the behavior of Janus particles, the hydroxyl group of particles and Rhodamine B dye were synthesized by applying the Steglich esterification reaction. This synthesis method has the advantage of having a high monodispersity, a clear hydrophilic surface, and preventing contamination of the dispersion medium. |
