Stimulus-responsive polymer gel materials were studied and applied widely in many fields in recent years. However, the poor electrically conductive property and even with poor toughness largely limit their extensive applications in more expanded fields. Herein, we report a novel kind of self-oscillating gels poly(acrylamide-co-acrylic acid-co-Fe(phen)₃)/reduced graphene oxide (poly(AM-co-AC-co-Fe(phen)₃)/RGO) with excellent electrical conductivity, and compressive strength via an in-situ polymerization accompanied by an ultrasonic assisted method. The dispersed reduced graphene oxide (RGO) improved the conductive and mechanical properties of the prepared materials remarkably. The conductivity of gel reached to 16.88 S·m⁻¹ with the content of 0.34 wt% RGO and the maximum fracture pressure was 4.1 MPa, which is as high as human cartilage. Besides, the prepared gels exhibited the self-oscillating behavior in the Belousov-Zhabotinsky (BZ) solution free of catalyst. Therefore, the prepared materials have potential applications as artificial cartilage and soft electron instrument.

近年来，对刺激响应性聚合物凝胶材料进行了研究并广泛应用于许多领域。然而，差的导电性能甚至韧性差在很大程度上限制了它们在更扩展的领域中的广泛应用。在这里，我们报告了一种新型的自振荡凝胶聚（丙烯酰胺-共-丙烯酸-共-Fe（phen）₃）/还原氧化石墨烯（聚（AM-共-AC-共-Fe（phen）₃） / RGO）具有优良的导电性，和压缩强度通过一个原位聚合伴随超声辅助方法。分散的还原氧化石墨烯（RGO）显着改善了所制备材料的导电性能和机械性能。凝胶的电导率达到16.88 S·m ^-1，RGO含量为0.34 wt％，最大断裂压力为4.1 MPa，与人软骨一样高。此外，所制备的凝胶在不含催化剂的别洛乌索夫-扎博汀斯基（BZ）溶液中表现出自振荡行为。因此，制备的材料具有作为人工软骨和软电子仪器的潜在应用。
