Abstract Herein, we demonstrate a facile and scalable approach to prepare triple-scale colloidal particles via a one-step dispersion polymerization of glycidyl methacrylate and ethylene glycol dimethacrylate in a toluene/ethanol solvent mixture. The morphologies of the colloidal particles can be readily tuned by adjusting the composition of the binary solvent mixture and other copolymerization parameters. Based on the morphological evolution and size variations of the colloidal particles collected during the one-step dispersion polymerization process, a plausible formation mechanism was proposed for these triple-scale colloidal particles. The addition of toluene not only prolonged the nucleation time by increasing the solvency of the solvent mixtures, but also increased the swelling capability of the growing particles for the glycidyl methacrylate and ethylene glycol dimethacrylate. The formation of triple-scale structure was attributed to the elastic stress of the crosslinked polymer network, which extrudes the swellen monomer and crosslinker. In addition, colloidal particle with various surface roughness were utilized to stabilize Pickering emulsions, and the correlation between particle surface roughness and the properties of Pickering emulsion was also investigated. As the particle surface roughness increase, stable O/W Pickering emulsions with diameters of hundreds of microns were obtained.

三重胶体粒子的简便制备及其在Pickering乳液中的应用

摘要在此，我们展示了一种简便且可扩展的方法，通过甲基丙烯酸缩水甘油酯和二甲基丙烯酸乙二醇酯在甲苯/乙醇溶剂混合物中的一步分散聚合来制备三重胶体颗粒。通过调整二元溶剂混合物的组成和其他共聚参数，可以很容易地调整胶体颗粒的形态。基于一步分散聚合过程中收集的胶体颗粒的形态演变和尺寸变化，提出了这些三重胶体颗粒的合理形成机制。甲苯的加入不仅通过增加溶剂混合物的溶解能力来延长成核时间，但也增加了甲基丙烯酸缩水甘油酯和乙二醇二甲基丙烯酸酯的生长颗粒的溶胀能力。三重结构的形成归因于交联聚合物网络的弹性应力，其挤出膨胀的单体和交联剂。此外，利用不同表面粗糙度的胶体颗粒稳定Pickering乳液，并研究了颗粒表面粗糙度与Pickering乳液性能之间的相关性。随着颗粒表面粗糙度的增加，获得了直径为数百微米的稳定的 O/W Pickering 乳液。此外，利用不同表面粗糙度的胶体颗粒稳定Pickering乳液，并研究了颗粒表面粗糙度与Pickering乳液性能之间的相关性。随着颗粒表面粗糙度的增加，获得了直径为数百微米的稳定的 O/W Pickering 乳液。此外，利用不同表面粗糙度的胶体颗粒稳定Pickering乳液，并研究了颗粒表面粗糙度与Pickering乳液性能之间的相关性。随着颗粒表面粗糙度的增加，获得了直径为数百微米的稳定的 O/W Pickering 乳液。
