用 Monte Carlo方法对两嵌段共聚高分子在固液界面的吸附进行模拟 ,获得了固液界面区吸附链节的分布和吸附构型大小分布等微观信息 .考察了吸附性链节的吸附能 εAa和两嵌段共聚高分子中吸附性链节比例 f对固液界面区高分子链节的分布和各种吸附构型大小的影响 .结果表明 ,吸附层厚度主要由两嵌段共聚高分子中非吸附性链段的长度决定 .
Monte Carlo method was used to simulate the adsorption of diblock copolymer on the solid-liquid interface, and the microscopic information of the distribution of adsorption units and the size distribution of adsorption configuration were obtained. The adsorption energy εAa and the ratio of adsorptive units f in the two-block copolymerized polymer to the distribution of polymer chain segments in the solid-liquid interface and the size of various adsorption configurations.The results show that the thickness of the adsorbed layer mainly consists of diblock copolymer The length of the non-adsorbing segment in the polymer is determined.
