本文介绍了低温胶体粒子的形成（苯乙烯-丙烯酸丁酯共聚物）的水包油和水包油系统。对烧结条件的研究检查了形成的最终壳形态，其中较长的烧结时间和较高的烧结温度产生较少的多孔微胶囊。这已经通过包封的染料从水性芯微胶囊的释放得到验证，其中对于较长的烧结时间已经检测到较慢的释放。随后将结果与扩散方程拟合，得到荧光素通过聚合物壳的扩散系数为10（-17）m（2）/s。
This paper presents the formation of low temperature colloidosomes from colloidal poly(styrene-co-butyl acrylate) particles for both water-in-oil and oil-in-water systems. An investigation into the sintering conditions examines the ultimate shell morphology formed, with longer sintering times and higher sintering temperatures producing less porous microcapsules. This has been verified by the release of an encapsulated dye from the aqueous core microcapsules, in which slower release has been detected for longer sintering times. The results are subsequently fitted with a diffusion equation to give a diffusion coefficient of fluorescein through the polymeric shell of 10(-17) m(2)/s.
