无机盐驱动下PCL-b-PEO结晶性胶束的形貌转变[EB/OL]
北京：中国科技论文在线
本文采用在无机盐溶液中透析和胶束制备后加入无机盐的两种方法将无机盐（NaNO3和NaCl）引入PCL-b-PEO结晶性胶束水溶液
采用TEM和DLS测试方法研究无机盐对于胶束形貌的影响
实验发现：无机盐可以诱发PCL-b-PEO胶束由球状到棒状和片状形貌的转变
必然需要考虑到无机盐对于胶束形貌的影响
并且这种诱发作用强弱与PCL分子链长度
） Abstract： The effect of inorganic salt at concentrations typical of a biological environment on the Micellar morphology of semicrystalline PCL-b-PEO in aqueous solution is investigated
The salt is introduced either by dialysis of a THF solution against an aqueous solution of the salt or by adding it into an aqueous solution containing preformed micelles
The inorganic salt can induce sphere-to-rod or sphere-to-lamella transformations of the PCL-b-PEO micelles in aqueous solution, affected by the length of the PCL block, the method of salt-adding and the concentration of inorganic salts
The inorganic salt induces ''salting-out'' of the PEO block, leading to a decrease in the reduced tethering density of the corona in the micelles
