Theoretical aspects of "switchable" two-component polymer brushes shall be investigated, studying generic models by analytic theory, computer simulation, and numerical selfconsistent field theory. The case shall be considered that the minory component polymer in the brush can undergo conformational transitions, e.g. between an adsorbed "pancake" state and a non-adsorbed "flower" state. Also concave cylindrical brushes that can serve as nanovalve will be studied, as well as the response to temporally periodic extemal stimulations. Comparing the different methods we shall clarify for which regions these methods are applicable and yield correct results. It is also the aim to make predictions that can be checked by experiment.

“可切换”的双组分聚合物刷的理论方面进行调查，研究通用模型的分析理论，计算机模拟，和数值自洽场理论。应考虑刷中的次要组分聚合物可以经历构象转变的情况，例如在吸附的“饼”状态和非吸附的“花”状态之间。还将研究可用作纳米阀的凹圆柱形刷，以及对时间周期性外部刺激的响应。比较不同的方法，我们将阐明这些方法适用于哪些地区，并产生正确的结果。它的目标也是做出可以通过实验检验的预测。
