Nanoparticles for Stabilizing Pickering High Internal Emulsion and Functionalization of PolyHIPEs Materials

高内相乳液(HIPEs)模板法因其可精确调控孔结构、操作简便等优点而被广泛应用于制备多孔材料。具有两亲性的固体粒子(NPs)可吸附在乳液的油水两相的界面稳定HIPEs,在多孔材料的制备过程中起着不可或缺的作用。近年来,NPs的作用不仅限于乳液的稳定,还可对多孔材料进行功能化。本文总结了包括改性NPs在内的常用NPs的种类,即无机粒子、生物相容性粒子、碳粒子、胶体粒子,介绍了不同NPs对HIPEs稳定性的影响及其引入后赋予多孔材料的功能化特点(生物相容性、导电性、刺激响应性、选择吸附性)。

High internal phase emulsions(HIPEs) template method is widely used in preparing porous material due to its advantages of precise control of pore structure and easy operation. Amphiphilic nanoparticles(NPs) can adsorb at the interface between oil phase and water phase to stabilize HIPEs, which plays an indispensable role in the preparation of porous material. In recent years, not only are NPs applied for the stability of emulsions, but they can functionalize the porous material. This review summarizes the types of commonly used NPs including modified NPs, namely inorganic particles, biocompatible particles, carbon particles, colloidal particles, and introduces in detail the influence of different NPs on the stability of HIPEs and the functionality of porous materials after introduction(biocompatibility, conductivity, stimulusresponsiveness, selective adsorption).
