| 中文摘要 | the influence of molecular topology on the structural and dynamic properties of polymer chain in solution with ring structure, three-arm branched structure, and linear structure are studied by molecular dynamics simulation. at the same degree of polymerization (n), the ring-shaped chain possesses the smallest size and largest diffusion coefficient. with increasing n, the difference of the radii of gyration between the three types of polymer chains increases, whereas the difference of the diffusion coefficients among them decreases. however, the influence of the molecular topology on the static and the dynamic scaling exponents is small. the static scaling exponents decrease slightly, and the dynamic scaling exponents increase slightly, when the topology of the polymer chain is changed from linear to ring-shaped or three-arm branched architecture. the dynamics of these three types of polymer chain in solution is zimm-like according to the dynamic scaling exponents and the dynamic structure factors. |
