Self-healing conductive elastomers have emerged as a class of novel materials that are important for fabricating human-motion sensors, soft robots and healthcare monitoring systems. Herein, we report on a hydrogel of modified poly(γ-glutamic) acid polymer chains crosslinked by coordination complexes, which exhibits good stretchability (1375%), long-term stability (more than 40 days), and self-healing ability (99.0 ± 1.5% in 3 h). Furthermore, a "sandwich" structure composite was fabricated, which is composed of self-healing hydrogels and Au nanograin-decorated aligned multiwall carbon nanotube sheets. It possesses fast self-healing ability, a low stable electronic resistance of 10 ± 1 Ω sq, in the temperature range of -40-90 °C, the humidity range of 10-90%, and a stretching range up to 200%.
自修复导电弹性体作为一类新型材料已经出现,它们在制造人体运动传感器、软体机器人和医疗保健监测系统方面非常重要。在此,我们报告了一种由配位复合物交联的改性聚(γ-谷氨酸)聚合物链水凝胶,它具有良好的拉伸性(1375%)、长期稳定性(超过 40 天)和自修复能力(3 小时内达到 99.0±1.5%)。此外,还制备了一种“三明治”结构复合材料,它由自修复水凝胶和 Au 纳米颗粒修饰的取向多壁碳纳米管片组成。它具有快速的自修复能力,在-40-90°C 的温度范围、10-90%的湿度范围和高达 200%的拉伸范围内,稳定电子电阻低至 10±1Ωsq。
