从理论上讨论了聚合物刷到交联弹性体（化学性质相同的刷）的渗透，使用自洽的平均场理论。的微观界面结构的系统（刷的厚度，自由能，弹性体和接枝链的体积分数，分布的自由链端，和梳齿长度的弹性体的轮廓）的细节得到。这些结果使人们能够计算刷子和弹性体之间的粘附能，并重新研究Brochard-Wyart等人的模型[J. Phys. Chem. 1993，98，9405]。将新模型的预测与最近的一些实验报告进行了比较（Weton等，Macromolecules 1994，27，3174）。
The penetration of a polymeric brush into a cross-linked elastomer (chemically identical to the brush) is discussed theoretically, using a self-consistent mean field theory. The details of the microscopic interfacial structure of the system (thickness of the brush, free energy, profiles of elastomer and grafted chain volume fractions, distribution of free chain ends, and interdigitation length of the brush into the elastomer) are obtained. These results allow one to calculate the adhesion energy between a brush and an elastomer and to revisit the model of Brochard-Wyart et al. [J. Phys. Chem. 1993, 98, 9405]. The predictions of the new model are compared with some recent experimental reports (Creton et al. Macromolecules 1994 , 27, 3174).
