The rheological and self-healing behavior of a class of catalytically synthesized amine-functionalized polyolefins is investigated. We demonstrate that these materials possess tunable rheological properties according to the molecular weight and display autonomous self-healing. The linear viscoelastic properties are modeled using a tube-based model developed by Hawke et al. [J. Rheol., 60, 297–310, (2016)] to calculate several model parameters that describe the individual chain dynamics. The self-healing response is described by findings from the reptation model as well as recent theory on associating polymer networks with reversible bonds. The cooperation between experiments, modeling, and theory provide insight into designing new materials with programmable rheological properties and superior self-healing ability.

胺官能化聚烯烃的流变学和自修复

研究了一类催化合成的胺官能化聚烯烃的流变学和自愈行为。我们证明这些材料具有根据分子量可调的流变特性并显示出自主自愈。使用由 Hawke等人开发的基于管的模型对线性粘弹性特性进行建模。[J。流变，60, 297–310, (2016)] 来计算描述单个链动力学的几个模型参数。自我修复反应是通过来自爬行模型的发现以及最近关于将聚合物网络与可逆键相关联的理论来描述的。实验、建模和理论之间的合作为设计具有可编程流变特性和卓越自愈能力的新材料提供了见解。
