摘要

本篇研究係以W/O型的微膠囊為主，並以油包水的原理進行實驗，以SM為膜材水溶性顏料為蕊材，BPO為起始劑，PVA水溶液為分散劑，文中並探討各種包覆條件PVA水溶液之添加量、攪拌速度的改變與制放性等，而進行以界面聚合法的微粒包覆。透過實驗得知添加少量的界面活性劑，所得的微膠囊溶液不易分散。而在制放性方面，轉速愈快，膠囊愈小，其制放愈快；反之，則較慢。

The study is regard the microcapsule of the type of W/O, and the principle that oil wrap aqueous to experiment, regarding SM ass the membrane, water-soluble color is for the core, BPO is for the initiative agent, aqueous solution of PVA is for the live of interface agent, in the text we study every kind the term of wrap, for example, increase the quantity of PVA solution, change the blend speed, and its release system, etc., but proceed with the that the interface come together the particle of the method to wrap. Through the experiment adds a little amount, the tiny aqua of capsule of the income is not easy asunder, but put the aspect of in release system, and the capsule is more small in its release system is more bad; whereas, than good.
