Reaction Steps
1 g of the amphiphilic macromolecule reversible addition-fragmentation chain transfer agent and 80 g of deionized water were formulated into an aqueous solution as an aqueous phase, which was added and uniformly mixed with an oil phase consisting of 6 g of styrene, 12 g of p-vinyl benzene, 0.1 g of azobisisobutyronitrile and 9 g of n-octane, and prepared by an ultrasonic crasher into a miniemulsion under the effect of a high shear field. The miniemulsion was transferred to a reactor and subjected to the reaction at a temperature of 80° C. which stopped after 4 hours, and then cooled to the room temperature and discharged to yield polymeric nanocapsules with highly crosslinked shells which were formed by the polymerization of styrene and p-divinyl benzene, wherein the polymeric nanocapsules have an average diameter of 90 nm.
