Water pollution is a severe worldwide issue. Constructing advanced porous composite materials has been an efficient route to water remediation via adsorption. In this study, a unique microspheres-in-pores monolithic structure was fabricated. An emulsion-templated polymer monolith was first prepared and silica microspheres were subsequently formed in the porous polymer. A silica precursor was modified with a fluorescent dye and co-condensed with other precursors to fabricate porous composites with fluorescent properties, which were enhanced by the presence of Ag nanoparticles in the polymer matrix. This unique material showed good promise in water remediation by removing organic dyes and heavy metal ions from wastewater via a flowing filter or monolithic column separation.
水污染是一个严峻的全球性问题。构建先进的多孔复合材料一直是通过吸附进行水修复的有效途径。在本研究中，制备了一种独特的孔内微球整体结构。首先制备了乳液模板聚合物整体材料，随后在多孔聚合物中形成二氧化硅微球。用荧光染料对二氧化硅前驱体进行改性，并与其他前驱体共缩聚以制备具有荧光特性的多孔复合材料，聚合物基体中银纳米颗粒的存在增强了其荧光特性。这种独特的材料在通过流动过滤器或整体柱分离从废水中去除有机染料和重金属离子的水修复方面显示出良好的前景。
