## Description

- description: A polymer solution can be flash-frozen to prepare homopolymers with
    mesoporous structures in a template-free manner. The flash-freezing method is
    derived from the ice-templating or freeze-casting method. Herein, we comprehensively
    investigated the effects of 13 good solvents for polystyrene as well as the polystyrene
    concentration on the fabrication process. Solvents with high boiling-point-to-melting-point
    ratios yielded uniformly sized mesoporous polystyrenes at polymer concentrations
    ≥20 wt %. Such solvents provided a high specific surface area (328 m2/g) and a
    large mesopore volume (1.78 g/cm3) at the optimal polystyrene concentration. Solvents
    with medium-boiling-point-to-melting-point ratios formed bimodal mesopores, while
    a low polystyrene concentration gave hierarchical structures composed of mesopores
    and macropores. These results provide an understanding of the mechanism associated
    with the formation of mesopores and enable control over the desired mesopore morphology.
