| 摘 要： | 采用荧光光谱法研究了苯乙烯—氧乙烯两亲接枝共聚物 (PS-g -PEO)在选择性溶剂甲苯中的性质 .研究发现两亲接枝共聚物在选择性溶剂中可以形成胶束 .而胶束的形成受浓度、温度以及两亲接枝共聚物结构等因素的影响 .温度越高 ,形成胶束的临界胶束浓度 (CMC)值越小 ;分子中接枝链越短 ,其CMC值也越小 ;PEO含量越大则CMC值越小 ;而当PS -g-PEO共聚物分子量越小时其CMC值越小 ,胶束也越稳定

| Abstract: | The property of amphiphilic graft copolymer polystyrene-graft-poly(oxyethylene) (PS-g-PEO)in selective solvent,toluene,has been studied by means of fluorescence measurement.It has been found that the micelles form when amphiphilic graft copolymer is dissolved in selective solvent,the micelle formation of PS-g-PEO in toluene is strongly dependent on concentration,temperature and the structure of the amphiphilic graft copolymer;moreover,the CMC value is affected by temperature,PEO content and the PEO side chains lengths in PS-g-PEO amphiphilic graft copolymer etc.,the higher of the temperature and the shorter of the PEO side chains length,the less of the CMC value. |
