Associative polymer networks have shown major promise in the fabrication of self-healing and responsive materials. They can also serve as simple models to study more complex biological systems in which transient interactions play an important role. In this work, we investigate the properties of charged polymer blends whose constituents are capable of creating dynamic bonds. We model dynamic bonds as harmonic springs with additional bond formation energy, ε_a, which can be adjusted to influence the reaction rates for binding and unbinding. We show that varying the number of binding sites on the chains and ε_a has a major effect on the resulting phase diagram. We further investigate the diffusive behavior of the coacervates. We also study how the network structure changes with varying number of active site, and increasing ε_a, and identify the values which result in the network percolation. Lastly, we explore the possibility of inducing orthogonal phase separation by introducing a second type of binding site, which cannot interact with the first kind.

缔合相互作用对复杂凝聚层相行为的影响

缔合聚合物网络在制造自修复和响应材料方面显示出巨大的前景。它们还可以作为简单的模型来研究更复杂的生物系统，其中瞬态相互作用发挥着重要作用。在这项工作中，我们研究了带电聚合物共混物的特性，其成分能够形成动态键。我们将动态键建模为具有额外键形成能 ε _a的谐波弹簧，可以调整该能量以影响结合和解离的反应速率。我们表明，改变链上结合位点的数量和 ε _a对所得相图有重大影响。我们进一步研究凝聚层的扩散行为。我们还研究了网络结构如何随着活性位点数量的变化以及 ε _{a 的}增加而变化，并确定导致网络渗透的值。最后，我们探索了通过引入第二种类型的结合位点诱导正交相分离的可能性，该结合位点不能与第一种结合位点相互作用。
