We systematically probe the morphology evolution of chemically anisotropic colloids prepared by homopolymerization- and copolymerization-induced phase separation during seeded emulsion polymerization using non-crosslinked seeds. Selective dissolution of one phase reveals the extension of patchy-Janus surface properties into the colloid interior. Incorporating a comonomer in the seeded emulsion changes the progression of phase separation resulting in different internal morphologies. Varying the monomer feed composition and concentration controls the morphology of kinetically-trapped internal microdomains and produces composite particles that can serve as templates for porous colloids. Examination of the morphological evolution illuminates fundamental principles dictating phase separation and its impact on the global particle morphology while also generating opportunities to exploit both surface and interior properties.

探索通过均聚和共聚诱导的相分离制备的化学各向异性胶体的形态演变†

我们系统地探讨了通过使用非交联的种子在乳液聚合过程中均聚和共聚诱导的相分离制备的化学各向异性胶体的形态演变。一相的选择性溶解揭示了斑片状贾纳斯表面特性在胶体内部的扩展。在种子乳液中掺入共聚单体会改变相分离的进程，从而导致内部形态不同。改变单体进料的组成和浓度可控制动力学捕获的内部微区的形态，并产生可作为多孔胶体模板的复合颗粒。
