论文摘要
尽管有理论上的预测[\ textit {ur。关于批量混合物和非吸附聚合物的混合物的实验研究很少。在本文中，\ textIt {n，-n-}二甲基甲酰胺中的空心二氧化硅纳米管和线性聚苯乙烯的混合物用于测量胶体立方体的结构因子作为非吸附聚合物浓度的函数。与视觉观察一起，这些结构因子使我们能够评估立方聚合物混合物的耗尽介导的相位稳定性。尽管所采用的理论的基础简化了，但立方排泄物混合物的理论和实验相边界仍具有显着的一致性。
Although there are theoretical predictions [\textit{Eur.~Phys.~J.~E} \textbf{41} (2018) 110] for the rich phase behaviour of colloidal cubes mixed with non-adsorbing polymers, a thorough verification of this phase behaviour is still underway; experimental studies on mixtures of cubes and non-adsorbing polymers in bulk are scarce. In this paper, mixtures of hollow silica nanocubes and linear polystyrene in \textit{N,-N-}dimethylformamide are used to measure the structure factor of the colloidal cubes as a function of non-adsorbing polymer concentration. Together with visual observations these structure factors enabled us to assess the depletion-mediated phase stability of cube-polymer mixtures. The theoretical and experimental phase boundaries for cube-depletant mixtures are in remarkable agreement, despite the simplifications underlying the theory employed.
