| Abstract: | Using polyurethane(PU) as the outer membrane,the fragrant microcapsules(MC) are prepared by a interfacial polycondensation method.The dispersivity and structure of MC are observed with microphotography.The permeability of MC outer membrane is described approximately by baking process and the quantitative evaluation by Index of Permeability (IP) is put forward by the author.In this paper the properties of MC and factors affecting them are discussed. |
