Abstract

Colloids are progressively expanding our technological ability to create new materials. However, there are substantial challenges in creating customized colloids that exhibit specific structural features, programmable binding, and stimulus responsiveness. Here, we explore an advantageous approach to achieve structural control over colloidal size by leveraging the absorption of polymeric micelles through fine thermal modulation. Polymeric micelles are used to swell the interstices of oligomeric colloidal droplets with the accuracy provided by the well-defined polymer micellization transition. Temperature and polymer concentration become the sole parameters governing not only the structure of colloids but also their interactions with the environment. Relevant colloidal phenomena like emulsion packing and droplet polymerization can be continuously tuned to any practical value, given the broad range of colloidal stability. The controlled absorption of polymeric micelles in bulk offers new opportunities to direct the transport of molecules for applications in physical and life sciences.

通过胶束吸收控制胶体大小
胶体正在逐步扩大我们创造新材料的技术能力。然而,要创造出具有特定结构特征、可编程结合和刺激响应性的定制胶体,还面临着巨大的挑战。在此,我们探索了一种有利的方法,即利用聚合物胶束的吸收能力,通过微热调制实现对胶体大小的结构控制。聚合物胶束用于膨胀低聚胶体液滴的间隙,其精确性由明确定义的聚合物胶束化转变提供。温度和聚合物浓度不仅是调节胶体结构的唯一参数,也是胶体与环境相互作用的唯一参数。由于胶体稳定性的范围很广,乳液堆积和液滴聚合等相关胶体现象可以不断调整到任何实际值。散装聚合物胶束的可控吸收为引导分子传输提供了新的机会,可应用于物理和生命科学领域。
