| 中文摘要 | based on lattice model monte carlo simulations were carried out to investigate the influence of channel confinement on the properties of entangled (linear-250) and disentangled (linear-30) linear polymers with different sizes of channel. it is found that the molecular size of both linear-30 and linear-250 monotonously decreases with decreasing the channel size, i.e. channel confinement has similar influence on the static properties of linear chains whether they are entangled or not. as for the dynamical properties, the diffusion coefficient of linear-30 decreases with decreasing channel size; while that of linear-250 first increases and then decreases, which implies that the confinement will help to untangle the linear chains. furthermore, the single target ring (which can be regarded as a test chain) in the matrix of confined linear-30 and linear-250 systems is also studied. the static properties of the target ring do not show clear change for these two systems; however, the diffusion coefficients of z direction of ring in the entangled linear matrix show great difference from that of the disentangled one. this is a further evidence for the untangle effect of confinement. |
