Study of Physical Properties of Ring Polymer Confined in Obstacles

环状聚合物被限制在有障碍的空间中，其行为被认为类似于支化聚合物(晶格动物)。我们在二维正方形障碍格子空间中研究了环状聚合物。证实了基于斑点图的标度关系可以很好地描述排除体积约束聚合物的行为。我们还研究了对应于粗粒模型的支化聚合物，它的键数在不变的情况下随机移除和添加。

Behavior of a ring polymer confined in a space with lattice of obstacles is considered to be similarto that of a branched polymer (Lattice Animal). We examined the ring polymer in a space with square lattice of square obstacles in two dimensions. It isconfirmed thatbehaviors of the confinedring polymer with excluded volume can be understood by scaling relations based on blob picture.We also studied correspondenceto coarse grained model a branched polymer with randomly removing andadding underconstant number of bonds.
