摘要
通过两步法制备了一种三硅氧烷型吡啶类离子液体表面活性剂([Si(3)Py]Cl),用IR、1H NMR和13C NMR对产物的结构进行表征,表面活性和聚集行为通过表面张力仪、动态光散射(DLS)和负染色透射电镜(TEM)进行测量.结果表明:[Si(3)Py]Cl具有良好的表面活性,其cmc为24.81 mmol/L,γcmc为23.04 mN/m,在水溶液中能聚集成直径为50-100 nm的囊泡.
A kind of trisiloxane-based pyridinium ionic liquid surfactant([Si(3)Py]Cl) was prepared via a two-step method.The structure of [Si(3)Py]Cl was characterized by IR,1H NMR and 13C NMR.The surface activity and aggregation behavior were measured by surface tension meter,dynamic light scattering(DLS) and negative-stain transmission electron microscopy(TEM).The results showed that [Si(3)Py]Cl had good surface activity,the cmc and γcmc of [Si(3)Py]Cl were 24.81 mmol/L and 23.04 mN/m,respectively,which could aggregate into vesicle with 50~100 nm of diameter in aqueous solution.
