论文摘要
我们研究了在表面吸附的线性块共聚物的自我避免行走模型，并被力的作用解吸。我们严格地确定自由能对吸附和力参数的依赖性，以及几种情况的相图形式，包括$ ab $ -diblock共聚物和$ aba $ -triblock copolymers，从末端顶点和中央顶点从端顶点和中央顶点中脱离。我们对块共聚物的兴趣部分是由于在二嵌段共聚物的定向步行模型\ cite {iliev}的定向步行模型中发生了一种新型混合阶段，我们相信本文是对这种情况的自我避免行走模型的第一个严格处理。
We investigate self-avoiding walk models of linear block copolymers adsorbed at a surface and desorbed by the action of a force. We rigorously establish the dependence of the free energy on the adsorption and force parameters, and the form of the phase diagram for several cases, including $AB$-diblock copolymers and $ABA$-triblock copolymers, pulled from an end vertex and from the central vertex. Our interest in block copolymers is partly motivated by the occurrence of a novel mixed phase in a directed walk model of diblock copolymers \cite{Iliev} and we believe that this paper is the first rigorous treatment of a self-avoiding walk model of the situation.
