| 英文摘要 | monodisperse polystyrene(ps) microcapsules containing vitamin e(ve) were prepared by membrane emulsification-dying in liquid technique. the diameter of microcapsules was about 4 times the size of the pore diameter of shirasu porous glass (spg) membrane, and the coefficient of variation (cv) of the microcapsule size was less than 0.2, showing a good monodispersity. furthermore, the effects of the ratio of ps to ve ( m/m) and the diameter of microcapsules on the release characteristics were investigated. when the ratio of ps to ve ( m/m) is 40/1, the permeability coefficients were 0.71 x 10(-9) and 0.74 x 10(-9) m (.) s(-1) corresponding to the microcapsule diameters of 21.32 and 11.45 mum, and the concentrations of ve released were 8 and 12 mg (.) l-1 respectively, which conform to the optimal concentration in applications. |
