Nanocapsules made of a cross‐linked poly(dodecafluoroheptyl acrylate) shell were successfully synthesized by interfacial RAFT miniemulsion polymerization. The well‐defined hollow fluorinated polymer structures were obtained by the subsequent removal of the liquid core materials. The core/shell ratio could be easily tuned up to 1:1 by changing the conditions. In the cases of high core/shell ratio of 1:2 and 1:1, the nanocapsules were severely deformed, which was improved by increasing the cross‐linker amount up to 30 wt.‐%. It was concluded that the utility of the interfacial RAFT miniemulsion polymerization overcame the thermodynamic and kinetic barriers in a conventional miniemulsion polymerization.
