摘要:建立了文题数学模型,采用计算机数值模拟计算进行求解。结果表明,溶剂的性质、体相高分子极度、吸附能参数和高分子链长,对高分子在界面的吸附量具有重要影响;吸附高分子层厚度主要由伸展于溶剂中的tail形式链段所决定,tail形式高分子的构象对高分子吸附后体系性质有很大的影响。
The model of polymer adsorption in the system of colloid-polymer-solvent isestablished by using statistical mechanics mcthod and solvcd by using computer numericalmethod.The proccss of finding solution usually diverges,we find the better way to controlthe divergence and to improve the convergence of itcralion. The results show that the natureof solvent,bulk polymer concentration, adsorption energy parameter,chain length have im-portant effects on the adsorbed amoupt on the surface of colloid.The thickness of polymeradsorbed layer is mainly determined by the long‘ tails dangling into solution. Tails play animportant role in the interaction between two polymer-adsorbed partcles.
