The development of new styrene-based hyper-crosslinked nanocomposites (HCLN) containing mesoporous silica nanoparticles (MSN) is reported here as a new strategy to obtain functional high surface area materials with an enhanced hydrophilic character. The HCLN composition, morphology and porous structure were analyzed using a multi-technique approach. The HCLN displayed a high surface area (above 1600 m/g) and higher microporosity than the corresponding hyper-crosslinked neat resin. The enhanced adsorption properties of the HCLN towards polar organic dyes was demonstrated through the adsorption of a reactive dye, Remazol Brilliant Blue R (RB). In particular, the HCLN containing 5phr MSN showed the highest adsorption capacity of RB.
本文报道了一种新型苯乙烯基超交联纳米复合材料(HCLN)的开发,该材料含有介孔二氧化硅纳米颗粒(MSN),作为一种获得具有增强亲水性的功能性高比表面积材料的新策略。采用多技术方法对HCLN的组成、形态和多孔结构进行了分析。HCLN具有高比表面积(超过1600 m/g),且微孔率高于相应的超交联纯树脂。通过吸附活性染料雷马素亮蓝R(RB),证明了HCLN对极性有机染料具有增强的吸附性能。特别是,含有5phr MSN的HCLN对RB表现出最高的吸附容量。
