A Review on Materials Encapsulation Techniques and Study on the Micro/Nanocapsules with Polymethyl Methacrylate Shell

Enapsulation is a new technology with many applications in drug delivery, dyes, agriculture and self-healing polymers. Polymethyl methacrylate (PMMA) is one of the polymers that is widely used as shell material in encapsulation. The main approach for materials encapsulation using PMMA as shell is solvent evaporation technique form double water-oil-water emulsion. In the present study, first, the encapsulation of liquid materials with polymeric shell is studied and then the effective factors on the preparation of micro/nanocapsule with PMMA shell will be reviewed.
