A novel silica microcapsule containing MPTGE was prepared from maleopimaric acid glycidyl ester type epoxy resin (MPTGE),by sol-gel method in a surfactant stabilised O/W emulsion.In these microcapsules system,MPTGE was used as the core material,and SiO2 acted as the shell material that was formed via hydrolysis and subsequent polycondensation of tetraethyl silicate (TEOS) in the presence of an acidic as catalyst.Fourier transformation infrared spectroscope (FT-IR),Zeta size annalyer,Scanning electronic microscope (SEM) and optical microscope (OM) were used to determine chemical structure,particle size and morphology respectively.FT-IR analysis confirmed that the silica shell material was successfully fabricated onto the surface of the MPTGE core.Zeta images suggested that these micropsules presented a very samll size and the distribution was very narrow.SEM and OM photographs showed that the silica microcapsules exhibited a spherical morphology with a well-defined core-shell microstructure.All these results demonstrated that silica microcapsules containing MPTGE were successfully prepared.
