摘要：

A novel hydrophilic polysilane porous material prepared from a facile and eco-friendly strategy, which was templated from Angelica sinensis (A. sinensis)-stabilized water-based foam via a one-step integrated reaction of hydrolysis and polymerization was reported. The as-prepared porous materials had sufficient pore structure and excellent stability, and the separation efficiency for various oil-water mixtures could easily reach 97% after ten cycles and still maintain excellent oil-water separation efficiency in harsh environments, such as strong acid or alkali, high salinity and high temperature. More importantly, the polysilane porous materials also presented a well separation efficiency for O/W emulsion stabilized with cationic surfactant. Involved the excellent separation efficiency as well as the favorable stability and reusability, the novel polysilane porous material had the potential application in oil-water separation, and the green pathway can be regarded as an important reference for the fabrication of novel porous materials.
