Colloidal dispersions of epoxy-acid vitrimers have been synthesized by miniemulsion polymerization. This versatile strategy enables obtaining stable cross-linked particles, even from initially incompatible precursors, while minimizing hydrolysis of the ester bonds formed during the curing. After drying of the latexes, trans-esterification exchanges occurring at high temperatures through interparticle interfaces induces an efficient sintering into homogeneous cross-linked polymer films.

通过烧结 Vitrimer 纳米粒子从不混溶的前体形成交联膜

已经通过细乳液聚合合成了环氧酸玻璃体的胶态分散体。这种通用策略能够获得稳定的交联颗粒，即使是最初不相容的前体，同时最大限度地减少固化过程中形成的酯键的水解。胶乳干燥后，在高温下通过颗粒间界面发生的酯交换交换导致有效烧结成均匀的交联聚合物薄膜。
