Analysis of Release Behavior of Pressure Sensitive MF-Resin Microcapsules Containing CVL

By some assumed conditions and by Fick first law (first used for release behavior of microcapsules), the release dynamic equation of idealized microcapsules in liquid phase was established. With extraction method and spectrophotometer, the light absorbance of extracted liquid was measured, the release dynamics in liquid phase and some relatively release parameters were acquired. The experiment indicated: the release behavior of the CVL core permeated from the wall of microcapsules into the liquid phase matched with zero-order release equation basically.
