Abstract
A system and method are directed toward the synthesis of polymeric capsules using a phase inversion process by extrusion of polymeric droplets through a syringe-needle assembly or an iris-shutter mechanism. The polymeric solution may be prepared by dissolving PAN (polyacrylonitrile) polymer in DMF (Dimethyl Formamide) solvent at high temperature through continuous stirring. Following preparation of the capsules, further treatment was initiated using triethylamine in gelation bath to make the final product an efficient removal agent of water hardness.
