Abstract：Microcapsulesaretinycontainers withacore-shellstructure，capableofstoring various substancesandcontroling their release.Mostconventional microcapsule preparation strategiesuseemulsion droplets as templates toconstructcore-shel structures through thermalyinitiated polymerization，whichoften requires long-term high-temperaturereactions.This may cause demulsification of complex emulsion templates，thereby afecting the morphologyand structure of microcapsules. Photopolymerization technology，withitsadvantagesofhigheficiencyandmildconditions，isverysuitablefortherapid curing of complex emulsion templates and exhibits unique advantages in the preparation of microcapsules. In recent years， our research group hascombined photopolymerizationtechnology with phaseseparation withinemulsiondroplets toconstruct microcapsules.This ethodischaracterizedbymildconditions，high efficiency，rapidityadjustability，andcontroablity， and shows unique advantages in the large-scale preparation of microcapsules.This review summarizes the research progress in the preparation of microcapsules with adjustable structures and controlable properties basedon this method，including single-layerpolymermicrocapsules，multi-layermicrocapsules，hybridmicrocapsules，andmulti-compartmentmicrocapsules. It also discusses theconstructionofvariousfunctionalcoatings basedonthesemicrocapsules，andfinalyexplores theexisting problems and future development trends of this method for microcapsule fabrication.
