Polyaniline is a widely used conductive polymer known for its stability, high conductivity, and favorable redox properties. Monodisperse micron-sized polyaniline spherical particles are synthesized using two-phase droplet microfluidics from Aniline and Ammonium persulfate oxidative polymerization in an oil-based continuous phase. The morphology of the polymerized particles is porous in nature which can be used for encapsulation as well as controlled release applications. The properties of the polyaniline (PANI) particles are characterized by using UV-Vis spectroscopy, SEM and XRD to understand the relationship between their microstructures and stability. Glucose oxidase enzyme and Indomethacin are encapsulated inside PANI particles for glucose sensing and controlled release respectively.
