Research Abstract

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.
