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.
