This project emplys large scale simulations of amphiphilic co-networks using lattice-based Monte Carlo techniques, allowing to interpret experimental findings on such networks and to improve existing theoretical approaches for the resulting material properties. The main focus will be on structure formation, micro phase separation of different network components as a function of external stimuli, including hydrophilic or hydrophobic properties of the network components, type of solvent, and strain. In close collaboration with the experimental partners within this research network, embedding, storage, and possibly anisotropic transport of test molecules shall be investigated as a function of various control parameters. In addition to the topics of the first funding period, networks consisting of core-shell star polymers shall be examined, and exclusively covalent bonds between stars shall be replaced by combinations of irreversible and reversible bonds.

该项目采用基于晶格的Monte Carlo技术对两亲性共网络进行大规模模拟，从而解释此类网络的实验结果，并改进现有的理论方法以获得材料特性。主要关注的是结构的形成，不同的网络组件作为外部刺激的功能，包括网络组件的亲水性或疏水性，溶剂类型和应变的微相分离。与本研究网络内的实验合作伙伴密切合作，将研究测试分子的包埋、储存和可能的各向异性运输，作为各种控制参数的函数。除了第一个资助期的主题外，还将研究由核-壳星星聚合物组成的网络，并将用不可逆和可逆键的组合取代星星之间的纯共价键。
