| 摘 要： | 利用格子自洽场方法,通过计算系统相图和比热,研究了在对称两性三嵌段共聚物溶液体系中聚合物浓度对胶束聚集的影响.计算结果表明,随聚合物浓度的增加,胶束临界温度升高,并且在这个温度以下,胶束进一步聚集的范围和均一溶液/胶束转变的宽度都与聚合物浓度有关.

| Abstract: | By using self-consistent field theory lattice model,the effect of polymer concentration on micellar aggregation for symmetrical amphiphilic triblock copolymer solutions has been studied through calculating phase diagram and specific heat.It is shown that the critical micelle temperature (CMC) will rise when polymer concentration is increased. Below CMC,both temperature-dependent ranges of micellar aggregation and the transition broadness depend on polymer concentration. |

| Keywords: | amphiphilic block copolymer micelle polymer concentration self-consistent field theory |
