Microencapsulation of energy conversion photochromic materials with epoxy resin shell by interfacial polymerization

摘要

In this study,a novel type of photochromic spirooxazine microcapsule was prepared by mterfacial polymerization between epoxy resin and polyamine compound The effects of different process parameters on the formation,microstructure and performance of microcapsules,such as curing reaction temperature,emulsification shear rate and the addition of silica nanoparticles were studied in this paper The morphology,microstructure,diameter and distribution,as well as the thermal stability of microencapsulated photochromic spirooxazine were also investigated by field emission scanning electron microscope,laser particle size analyzer and thermogravimetric analysis systematically.In addition,the photochromic performance of microcapsule was studied as well.
