摘要
The translocation of a confined polymer chain through an interacting nanopore has been studied using two-dimensional bond fluctuation model with Monte Carlo dynamics. For different pore-polymer interaction, the average escaping time （Tesc） of the polymer chain through the nanopore, increases roughly linearly with the chain length and the nanopore length~ respectively. However~ the large repulsive and attractive pore-polymer interaction adds the difficulty of the monomers of the chain entering and leaving the nanopore, respectively, leading to the nonmonotonical dependence of （Tesc） on the pore-polymer interaction. The detailed translocation dynamics of the chain through the interacting nanopore is inves- tigated too.
