Healable, Reconfigurable, Reprocessable Thermoset Shape Memory Polymer with Highly Tunable Topological Rearrangement Kinetics Zizheng Fang Ning Zheng Qian Zhao Tao Xie 10.1021/acsami.7b05713.s001 https://acs.figshare.com/articles/journal_contribution/Healable_Reconfigurable_Reprocessable_Thermoset_Shape_Memory_Polymer_with_Highly_Tunable_Topological_Rearrangement_Kinetics/5144146 The unique capability of topological rearrangement for dynamic covalent polymer networks has enabled various unusual properties (self-healing, solid-state plasticity, and reprocessability) that are not found in conventional thermosets. Achieving these properties in one network in a synergetic fashion can open up new opportunities for shape memory polymer. To accomplish such a goal, the freedom to tune topological rearrangement kinetics is critical. This is, however, challenging to achieve. In this work, two sets of dynamic bonds (urethane and hindered urea) are incorporated into a hybrid network for synthesizing shape memory poly­(urea-urethane). By changing the bond ratio, networks with highly tunable topological rearrangement kinetics are obtained. Combining self-healing, solid-state plasticity, and reprocessability in one such shape memory network leads to unusual versatility in its shape-shifting performance. 2017-06-20 00:00:00 topological rearrangement Tunable Topological Rearrangement Kinetics plasticity tune topological rearrangement kinetics synergetic fashion bond ratio reprocessability self-healing shape memory network shape memory polymer covalent polymer networks tunable topological rearrangement kinetics shape-shifting performance Reprocessable Thermoset Shape Memory Polymer
