当分子链的一端附着于某一固体壁时,就形成了尾形高分子构象,显然,它可以看成是高分子吸附的最简单的形式,除高分子吸附与解吸外,许多涉及表面和界面的高分子问题都与尾形链的构象有关,例如固体表面上的接枝聚合、嵌段共聚体的液晶层状结构、高分子表面活性剂在两相的分配、高分子对于胶体的稳定性、橡胶单点粘结力学等.然而,尾形链分子构象理论的研究相当薄弱,众所周知,高分子构象问题与随机行走问题有明显对应关系,由简单随机行走导出的理想高分子链构象的Gauss分布,已经是整个高分
When one end of the molecular chain is attached to a solid wall, the polymer has a tail-shaped polymer conformation. Obviously, it can be regarded as the simplest form of polymer adsorption. In addition to polymer adsorption and desorption, many involve the surface and interface Of the polymer problems are related to the conformation of the tail-shaped chain, such as the graft polymerization on the solid surface, the liquid crystal layer structure of the block copolymer, the distribution of the polymer surfactant in the two phases, the stability of the polymer to the colloid, Rubber single-point bond mechanics, etc. However, the research on the molecular conformation theory of the tail-shaped chain is rather weak. It is well-known that there is a clear correspondence between the polymer conformation problem and the random walking problem. The Gauss distribution of the ideal polymer chain conformation derived from simple random walk, It is already the whole high score
