The results show that glycerol, as surfactant, with a concentration of I % can alternate the interfacial tension between water and oil to some extent; thusly, the conglomeration problem can be inhibited during the microencapsulation process. Meanwhile, by controlling the reaction rate of condensation polymerization and adjusting the pH of the system, the floccules can be restrained effectively, and microcapsules with smooth surfaces are obtained. Finally, the addition of NH4Cl may result in properly strengthened microcapsules to resist the collapse during nature drying.
