Polymerization-induced self-assembly is demonstrated as a powerful platform for the synthesis of block copolymers comprising a semifluorinated liquid-crystalline block. This strategy transforms the deficiency of polymer insolubility encountered in traditional homogeneous solution protocols to the strength for dispersion polymerization, thus, enabling direct access to polymorphic block copolymer nanoobjects at high concentrations and with quantitative conversions. The versatility of this strategy is highlighted by polymerizations in a wide selection of inexpensive solvents, from nonpolar to highly polar, to afford various block copolymers with distinct combinations of amorphous/crystalline or hydrophilic/hydrophobic/fluorinated segments. The utility of the nanoparticles is demonstrated as robust Pickering emulsifiers for commonly considered good solvents.

RAFT 聚合诱导自组装作为多功能合成半氟化液晶嵌段共聚物纳米物体的策略

聚合诱导的自组装被证明是合成包含半氟化液晶嵌段的嵌段共聚物的强大平台。该策略将传统均相溶液方案中遇到的聚合物不溶性缺陷转化为分散聚合的强度，从而能够直接获得高浓度和定量转化的多晶型嵌段共聚物纳米物体。该策略的多功能性通过在从非极性到高极性的多种廉价溶剂中进行聚合来突出显示，以提供具有无定形/结晶或亲水/疏水/氟化链段的不同组合的各种嵌段共聚物。
