摘要：

The molecular dynamics technique is used to investigate the effect of the approach and separation of two monolayers on the dynamics, structure, and chain conformation within each layer, and the total internal energy. The results show that at certain distances between the monolayers there is a strong increase in ordering, and that the internal energy during approach is consistently different from that during separation. Hysteresis effects in these simulations appear to be due to an order-disorder transition and not to chain entanglements between the monolayers.
