摘要：
A scaling analysis of the stretching of collapsed polymer brushes is presented. The stretching is associated with a first-order phase transition involving a coexistence of a collapsed layer and stretched chain segments. The coexistence regime is characterized by a f approximately L0 force law. Linear force laws are found for weaker as well as for stronger deformations.
