用蒙特卡罗方法研究了有限弯曲刚度κ‘对无自回避的柔性聚合表面的影响。与线性聚合物或液膜不同，这些表面经历了显著的有限温度皱缩转变，具有发散的比热。对于较小的κ‘/k BT，表面起皱，回转半径RG增长为ln L 1/2，其中L是未起皱薄膜的线性尺寸。对于大的κ‘/k B T，我们发现表面仍然是平坦的，即R G∼L。我们的结果强烈地表明，聚合自回避膜中也存在有限温度的皱缩转变。
The effect of a finite bending rigidity κ’on flexible, polymerized surfaces without self-avoidance is studied via the Monte Carlo method. Unlike linear polymers or liquid membranes, these surfaces undergo a remarkable finite-temperature crumpling transition, with a diverging specific heat. For small κ’/k B T, the surface is crumpled, and the radius of gyration R G grows as ln L 1/2, where L is the linear size of uncrumpled membrane. For large κ’/k B T, we find that the surface remains flat, ie, R G∼ L. Our results strongly suggest a finite-temperature crumpling transition in polymerized self-avoiding membranes as well.
