以交联壳聚糖膜为载体 ,芘为介质极性探针 ,制备并表征了一种介质极性敏感膜 ,研究了该膜对醇 -水混合溶剂极性的响应行为 .基于极性测定 ,对十二烷基硫酸钠 ( SDS)和十二烷基磺酸钠 ( SLS)水溶液中胶束的形成进行了检测 .结果表明 ,该膜具有较好的可逆性和重现性 ,且制膜方法简单、快速 A crosslinked chitosan membrane was used as a carrier and pyrene as a polar probe to prepare and characterize a medium-sensitive membrane. The response of the membrane to the polarity of alcohol-water mixed solvents was investigated. , The formation of micelles in aqueous solution of sodium dodecyl sulfate (SDS) and sodium dodecyl sulfate (SLS) was tested.The results showed that this membrane has good reversibility and reproducibility, Membrane method is simple and fast
