POLYMER SEMIPERMEABLE MICROCAPSULES USING PHOTOPOLYMERIZATION-INDUCED PHASE SEPARATION AND METHOD OF PREPARING SAME

摘要

The present invention relates to polymer semipermeable microcapsules using photopolymerization-induced phase separation, and a method of preparing the same. Specifically, the present invention relates to polymer semipermeable microcapsules and a method of preparing the same, wherein the polymer semipermeable microcapsules use the phase separation of porogen and polymer produced from emitting UV rays in double-emulsion drops in which photopolymerizable monomers and porogen form an intermediate phase to polymerize the monomers. The present invention may form uniform pores with controllable size in a shell by using the porogen type and concentration, and the phase separation characteristics thereof with polymer monomers. Since the present invention forms the shell by polymerizing photopolymerizable monomers, the present invention can provide microcapsules that are relatively independent of influences of solvents or pH conditions, are chemically stable, and have excellent mechanical characteristics as well. Also, the microcapsules of the present invention possess pores of a size ranging from a few nanometers to a few hundred nanometers and thus are capable of controlling materials flowing in and out of the interior of the microcapsules.;COPYRIGHT KIPO 2017
