The adhesion dynamics of a membrane confined between two permeable walls is studied using a two-dimensional hydrodynamic model. The membrane morphology decomposes into adhesion patches on the upper and the lower walls and obeys a nonlinear evolution equation that resembles that of phase-separation dynamics, which is known to lead to coarsening, i.e., to the endless growth of the adhesion patches. However, due to the membrane bending rigidity, the system evolves toward a frozen state without coarsening. This frozen state exhibits an order-disorder transition when increasing the permeability of the walls.
使用二维流体动力学模型研究了限制在两个可渗透壁之间的膜的粘附动力学。膜形态分解为上下壁上的粘附斑，并服从一个类似于相分离动力学的非线性演化方程，已知该方程会导致粗化，即粘附斑的无休止生长。然而，由于膜的弯曲刚度，系统朝着不粗化的冻结状态演化。当增加壁的渗透率时，这种冻结状态会出现有序-无序转变。
