在这项工作中，我们报告了石墨烯纳米复合纤维与不同聚合物基体材料的熔融纺丝和湿法纺丝。在熔纺情况下，据报道开发了一种采用含有 1 wt% 石墨烯的熔纺聚酰胺 6 纱线的纺织超级电容器。石墨烯/聚酰胺-6 的熔融纺丝以中试规模进行，卷绕速度为 1,400 m/min。随后，石墨烯/聚酰胺6纱线被加工成机织织物并转移到超级电容器中。寰纹和平纹机织物的电容量达到 1.14 和 1.82 mF/g。在湿纺情况下，报告了石墨烯和聚乙烯醇 (PVA) 的试验以及对所得纤维性能的研究。通过将 10 wt% 的石墨烯掺入聚合物材料中，可以观察到拉伸强度增加了约 10 倍。此外，还研究了干燥和拉伸的后处理步骤。
In this work, we report about melt- and wet-spinning of graphene nano-composite fibres with different polymer matrix materials. In case of melt-spinning, the development of a textile supercapacitor with melt-spun polyamide-6 yarns including 1 wt% of graphene is reported. Melt spinning of graphene/polyamide-6 is performed at pilot scale leading with winding velocities of 1,400 m/min. Subsequently, the graphene/polyamide-6 yarns are processed to woven fabrics and transferred into a supercapacitor. Electrical capacities of 1.14 and 1.82 mF/g are achieved for atlas- and plane-weave woven fabrics.In case of wet-spinning, trials with graphene and polyvinyl alcohol (PVA) and the investigation of the obtained fibres’ properties are reported. By incorporation of 10 wt% of graphene into the polymer material, an increase of the tensile strength about a factor of 10 can be observed. Furthermore, after-treatment steps of drying and drawing are investigated.
