Mimicking nature's self-healing ability has always been desired in science, especially when devices accumulate damage over time with performance, including the loss of function due to deterioration. SHAP (Self-Healing AETA([2-(acryloyloxy)ethyl]trimethylammonium chloride)-based Polymer), a hydrogel with autonomous self-healing ability that can be applied for the development of a pneumatic artificial muscle, is presented here. Unlike other self-healing hydrogels, SHAP does not require any external stimulus to self-heal and it presents outstanding anti-drying properties. Few-layer graphene is also incorporated into the polymer network of the hydrogel in order to study the possible influence that the nanomaterial has on the properties of the scaffolds. The mechanical behavior and the self-healing abilities of the resulting hydrogels are analyzed. Moreover, the mechanism of self-healing is discussed in terms of experimental results and theoretical calculations. The data suggest a mechanism based on strong hydrogen-bonding interactions between the water molecules that remain inside SHAP, which keeps the material wet and soft under ambient conditions. Finally, the development of a SHAP-based artificial muscle is presented. The results show good performance of the healed artificial muscles after damage, even with healing periods as short as 10 minutes.

模仿自然的自我修复能力一直是科学界所期望的，尤其是当设备随着时间的推移累积性能损害时，包括由于劣化而导致的功能丧失。SHAP（自修复AETA（[2-（丙烯酰氧基氧基乙基）三甲基氯化铵）基聚合物）是一种具有自主自修复能力的水凝胶，可用于开发气动人造肌肉。与其他自修复水凝胶不同，SHAP不需要任何外部刺激即可自修复，并且具有出色的抗干燥性能。几层石墨烯也被掺入到水凝胶的聚合物网络中，以研究纳米材料对支架性能的可能影响。分析了所得水凝胶的机械行为和自愈能力。此外，从实验结果和理论计算方面讨论了自愈机制。数据表明一种机理是基于保留在SHAP中的水分子之间的强氢键相互作用，从而在环境条件下保持材料湿润和柔软。最后，介绍了基于SHAP的人造肌肉的开发。结果表明，即使愈合时间短至10分钟，损伤后愈合的人造肌肉也具有良好的性能。介绍了基于SHAP的人造肌肉的开发。结果表明，即使愈合时间短至10分钟，损伤后愈合的人造肌肉也具有良好的性能。介绍了基于SHAP的人造肌肉的开发。结果表明，即使愈合时间短至10分钟，损伤后愈合的人造肌肉也具有良好的性能。
