Multiple shape memory polymers (MSMPs), capable of remembering multiple temporary shapes in response to distinct stimuli, hold broad prospects for application. The design of MSMPs generally extends from the concept of dual shape memory polymers, yet innovating methods for their design and preparation remain challenging. In this work, we drew inspiration from the spine and developed an approach for the design and preparation of MSMPs. This approach employs intramolecular hydrogen bonds and resistance among semirigid chains to stabilize all the transition states in situ. The formation of metastable states was used to shape the memory design. Through this strategy, we have synthesized a series of polynorbornene copolymers PNB-mSi-nAc-DCPD (m/n = 3/1, 1/1, or 1/3) with dual- and triple-shape memory effect when subjected to stimuli such as thermal, alcohol/water, and pH. Furthermore, these copolymers demonstrate superior self-healing, mechanical, and easy processing performance, markedly broadening their potential applications.

具有多刺激、多形状记忆和自修复性能的聚降冰片烯共聚物的受脊柱启发的制造
多重形状记忆聚合物（MSMP）能够记住多种临时形状以响应不同的刺激，具有广阔的应用前景。MSMP 的设计通常源自双形状记忆聚合物的概念，但其设计和制备的创新方法仍然具有挑战性。在这项工作中，我们从脊柱中汲取灵感，开发了一种设计和制备 MSMP 的方法。这种方法利用分子内氢键和半刚性链之间的电阻来原位稳定所有过渡态。亚稳态的形成被用来塑造存储器设计。通过这一策略，我们合成了一系列具有双重和三重形状记忆效应的聚降冰片烯共聚物PNB- mSi - nAc -DCPD（m / n =3/1、1/1或1/3）。热、酒精/水和 pH 等刺激。此外，这些共聚物表现出优异的自修复、机械和易加工性能，显着拓宽了它们的潜在应用。
