研究了在安全、温和的条件下制备几微米大小的水核胶体的方法。利用180 nm大小的聚（苯乙烯-丙烯酸丁酯）胶体颗粒，在30或42℃的低温玻璃化转变下，展示了自组装成微米大小的水核聚合物壳颗粒。考察了油相类型、表面活性剂和助溶剂、烧结时间以及转移到水相的方法等因素的影响。这项工作证明了在35到65摄氏度的低温下水核硬壳胶体体的生产。版权所有。
A method using safe and mild conditions to prepare water-core colloidosomes of a few micrometers in size is examined. Using poly(styrene-cobutylacrylate) colloidal particles of 180 nm in size, with a low-temperature glass transition of 30 or 42 degrees C, the self-assembly into micrometer-sized water-core polymer shell particles is demonstrated. The effect of oil phase type, surfactant and cosolvent, sintering time, and the method of transfer into an aqueous phase are all examined. The work demonstrates the production of water-core rigid-shell colloidosomes at low temperatures, between 35 and 65 degrees C. (c) 2007 Elsevier Inc. All rights reserved.
