Structured Polymer Colloids by Flash NanoPrecipitation
Invited
Abstract
Colloids with internal and external structure have shown great promise in applications ranging from biosensors to optics to drug delivery, where the overall particle structure is paramount to performance. The growing demand for such nanomaterials motivates the development of a scalable processing platform for their production. Here, we demonstrate that Flash NanoPrecipitation (FNP), a rapid and inherently scalable colloid precipitation technology, can be used to prepare structured colloids from homopolymers, polymer mixtures and block copolymers. As revealed by a combination of experiments and simulations, by varying key process parameters and functional groups within the polymers, a range of structured colloids can be produced without any modification to the FNP process. Finally, in one application, we demonstrate how ionomer-based Janus colloids can be used to stabilize Pickering emulsions.
