How to Make a Microcapsule?

Microcapsules can be prepared by emulsion polymerization (oil dispersed in continuous water phase) or inverse emulsion polymerization (water disperse in continuous oil phase) [89–91]. In emulsion polymerization, stirring or sonication creates droplets that become the core material of the capsule.

What is used as a coating material in microencapsulation?

Microencapsulation is a process in which tiny particles or droplets are surrounded by a coating to give small capsules, with useful properties. ... The coating materials generally used for coating are: Ethyl cellulose. Polyvinyl alcohol.

What are microencapsulated materials?

Microencapsulation is the protective technology of encapsulating solid, liquid or gas materials into micro particles with a diameter of 1–1000 μm, and has been widely used in fields of medicine, cosmetics, food, textile and advanced materials (Campos et al., 2013; Dubey et al., 2009).
