Polymer crystallization at liquid‐liquid interface

This is the authors' abstract. We don't add key points for this paper.

Most of the research activities in the field of polymer crystallization have been focused on bulk, solution, or thin films. Liquid/liquid (L/L) interface provides another insightful platform to manipulate the crystallization of long chain polymers. This review will discuss polymer crystallization influenced by or confined near/at L/L interfaces. Polymer blends and solution will be first discussed as the underlying liquid-liquid-phase separation (LLPS) generates L/L interface which strongly couples with crystallization. This will continue into a discussion of utilizing flat air/water interface where the fast dynamics offers a unique opportunity to tune crystal structure and crystallization. The focus will then be shifted to polymer crystallization confined at curved L/L interface where the crystallization process is simultaneously influenced by the interface chemistry and dynamics, LLPS within the droplet, and the confinement in such a curved environment. Manipulating this diverse parameter space has allowed the attainment of numerous novel crystalline and hybrid nanostructures.
