Abstract:
The variation of the translocation time with respect to the solvent quality was also studied. It showed that there is a transition, as the solvent quality improves from \poor to \good: when ABc, τ increases with increasing AB. When the chain length was changed, it was found that when the absorbed energy u0 was greater than uc, τ was proportional to N1:602; for u0

摘要:
采用Monte Carlo方法研究了高分子链穿越"trans"侧具有吸附作用的膜上纳米孔的过程. 当体系的温度TTc时,τ随着温度的升高而增大. 穿孔时间与膜的吸附势强度μ0 之间存在非单调依赖关系,τ首先随着μ0的增大而增大,最后τ随着μ0 的增大而减小. 研究穿孔时间与溶剂性质的关系时发现,当εAB<εc时,τ随着εAB 的增加而增加,当εAB>εc时,τ 随着"AB 的增加而减小. 高分子链穿孔时间与链长N之间存在着标度关系:当吸附势强度μ0>μc时,τ∝N^1.602,当μ0
