聚合物微胶囊已经合成了一个显着更多的亲水性单体比以前报道的，三甘醇二乙烯基醚，使用阳离子光聚合在水性环境中。通过NMR和SEM的表征表明，尽管在水性条件下具有预期的抑制作用，但所形成的颗粒具有约1 μ m的尺寸的低分散性。此外，超临界二氧化碳已被用于产生银纳米颗粒，其分布在整个微胶囊的壳中，进一步说明了这些胶囊的结构，并通过TEM和SAXS表征。
Polymeric microcapusles have been synthesised with a markedly more hydrophillic monomer than previously reported, triethylene glycol divinyl ether, using cationic photopolymerisation in an aqueous environment. Characterisation by NMR and SEM show that the particles are formed with low dispersity with a size of approximately 1 mu m in spite of the expected inhibition in aqueous conditions. Furthermore, supercritical carbon dioxide has been used to generate silver nanoparticles which distribute throughout the shell of the microcapsules further illustrating the structure of these capsules with characterisation by TEM and SAXS.
