Supramolecular materials have received considerable attention due to their higher fracture energy and self-recovery capability compared to conventional chemically cross-linked materials. Herein, we focus on the mechanical properties and self-recovery behaviours of supramolecular polymeric elastomers swollen with ionic liquid. We also gained insight into the correlation between ionic liquid content and mechanical properties. These supramolecular polymers with ionic liquid can be easily prepared from bulk copolymerization of the host-guest complex (peracetylated cyclodextrin and adamantane derivatives) and alkyl acrylates and subsequent immersion in ionic liquid such as 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide. The supramolecular polymeric elastomers showed a self-recovery ability, which the conventional chemically cross-linked elastomers with ionic liquid cannot achieve.
与传统化学交联材料相比，超分子材料因其更高的断裂能和自我恢复能力而受到广泛关注。在此，我们重点研究了用离子液体溶胀的超分子聚合物弹性体的力学性能和自我恢复行为。我们还深入了解了离子液体含量与力学性能之间的关系。这些含离子液体的超分子聚合物可通过主体 - 客体复合物（全乙酰化环糊精和金刚烷衍生物）与丙烯酸烷基酯的本体共聚，随后浸入离子液体（如1-乙基-3-甲基咪唑双（三氟甲基磺酰）亚胺）中轻松制备。超分子聚合物弹性体表现出自我恢复能力，这是含离子液体的传统化学交联弹性体无法实现的。
