A general strategy for nano-encapsulation via interfacially confined living/controlled radical miniemulsion polymerization

摘要

We propose and demonstrate the utility of an interfacial living/controlled (reversible addition fragmentation chain transfer, RAFT) radical miniemulsion polymerization in nano-encapsulation. The principles and methodology behind this technique are readily scalable and highly efficient. The living/controlled nature of the system offers great opportunities to tune the properties of the polymer shell-like thickness, surface functionality, molecular weight, and inner-wall functionality by simply using a semicontinuous polymerization technique.
