We review the elasticity of flexible and stiff polymer networks with permanent cross-links and synthesize these results into a unifying polymer chain network model. This framework is then used to address how the network elasticity becomes modified when the network cross-linking is thermoreversible in nature, changes in the stability of the network with deformation, and the effect of a variable rate of network deformation on the non-linear elastic response. Comparisons are made between this class of simplified network models with elasticity measurements performed on flexible chain and stiff fiber networks, both with permanent and associative cross-links. Although these network models are highly idealized, they are apparently able to capture many aspects of the elastic properties of diverse real networks.
我们回顾了具有永久交联的柔性和刚性聚合物网络的弹性，并将这些结果综合成一个统一的聚合物链网络模型。然后，该框架用于解决当网络交联本质上是热可逆时网络弹性如何被改变、网络稳定性随变形的变化以及网络变形速率变化对非线性弹性响应的影响。将这类简化网络模型与对具有永久交联和缔合交联的柔性链网络和刚性纤维网络进行的弹性测量进行了比较。尽管这些网络模型高度理想化，但它们显然能够捕捉各种真实网络弹性特性的许多方面。
