摘要:
A method for making microcapsules including an encapsulated material may include providing, in an aqueous continuous phase, one or more microcapsules including an encapsulated material surrounded by an inner shell including a first cross-linked polymer matrix. An outer surface of the inner shell may be hydrophobic. The method may also include adding thereto a polymerizable liquid component and a stabilizing agent, wherein the polymerizable liquid component is immiscible in the aqueous environment. The method may also include forming microcapsules wetted by the polymerizable liquid component. The method may further include polymerizing the polymerizable liquid component forming an outer shell including a second cross-linked polymer matrix formed about the inner shell. The microcapsules may be included in articles and compositions.
