| 摘 要： | In the present study,microcapsules with disperse dye solutions and a direct dye solution ascore materials were prepared by the complex coaeervation method and the interfacialpolycondensation method respectively.Experiments and theoretical analysis showed that there wasan exponential relationship between the diffusion time and the release rate of the core material intothe surrounding medium.A concise equation to calculate the permeability constant was derivedand verified by the experimental results.By means of duplex focus on the inner and outer diametersof a microcapsule,the average wall thickness of microcapsules was measured.
