论文摘要
微米大小的硬核壳壳混合型微凝胶是用于软物质研究的有前途的模型系统，因为它们可以实现现场光学研究，并且可以用大量的种类进行结构/形态。然而，很少有具有可定制的壳体与核心尺寸比率的微米大小的核壳微凝胶的协议。在这项工作中，我们报告了微米大小的二氧化硅 - 二氧化硅（N-异丙基丙烯酰胺）核壳微凝胶的一锅合成方案，该方案对壳核比率具有良好的控制。合成微凝胶的2-维组件的小角度光散射和显微镜证实，生产的微凝胶是单分散的，即使在高填充分数下也适用于光学研究。
Micron-sized hard core-soft shell hybrid microgels are promising model systems for studies of soft matter as they enable in-situ optical investigations and their structures/morphologies can be engineered with a great variety. Yet, protocols that yield micron-sized core-shell microgels with a tailorable shell-to-core size ratio are rarely available. In this work, we report on the one-pot synthesis protocol for micron-sized silica-poly(N-isopropylacrylamide) core-shell microgels that has excellent control over the shell-to-core ratio. Small-angle light scattering and microscopy of 2- and 3-dimensional assemblies of the synthesized microgels confirm that the produced microgels are monodisperse and suitable for optical investigation even at high packing fractions.
