摘要
采用嵌段共聚物聚氧乙烯-聚氧丙烯-聚氧乙烯(PEO-PPO-PEO,F127)和聚二甲基硅氧烷-聚氧乙烯(PDMS-PEO)为混合模板剂制备了有序介孔碳材料,并采用小角X射线散射(SAXS)和氮气吸附/脱附对其结构进行了表征,进一步研究了上述介孔碳材料对甲基橙、亚甲基蓝和碱性品红3种染料大分子的吸附性能。
Mixed amphiphilic block copolymers of poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) and polydimethylsiloxane-poly(ethylene oxide)(PDMS-PEO) were successfully used as co- templates to prepare ordered mesoporous carbon materials. The structure of materials was characterized by small-angle X-ray scattering(SAXS) and nitrogen-sorption measurements. The adsorption ability for methyl orange, methylene blue and basic fuchsin of resulting materials was investigated.
