碳纳米材料(碳纳米管、石墨烯、氧化石墨烯等材料)具有高比表面积和良好的化学稳定性，同时又具有碳材料自身的导电特性，可与其他材料混合制备功能性纤维或纱线。如碳基导电纤维，其质量轻，可根据不同的形状和尺寸需求来确定合适的制备方法，可纺性好，而且具有较好的机械性能和导电性能，可织造成纱线。碳基导电纱线同样具有导电纤维的这些优异性能，可使其在导电、传感等方面具有广阔的应用前景，如电子纺织品、表皮或植入式医疗设备、纳米机器人等。
发明内容
本发明使用碳纳米材料、聚己内酯在有机溶剂中充分混合搅拌，得到均匀溶液，进而利用静电纺丝装置制备包芯导电纱线。本发明制备的导电纱线具有导电传感、抗静电的特性，在复合材料领域具有广阔的发展空间。
为实现上述目的，本发明采用的技术方案如下：
(1)按照反应时所需浓度，称取一定质量的聚己内酯，溶解于有机溶剂内；
(2)按照所需浓度，称取一定质量的碳纳米材料；
(3)利用超声波细胞粉碎机，在冰水浴冷却条件下，将碳纳米材料分散于聚己内酯分散液内，得到纺丝液；
(4)用注射器吸取一定量纺丝液，固定在静电纺丝装置上，固定一根单股纯棉纱线，作为芯纱，设定电压、注射器移动速度、牵引速度，调整接收装置距离和角度。
上述步骤(1)中所述的有机溶剂可以为乙醇、异丙醇、六氟异丙醇等；
上述步骤(1)中所述聚己内酯的质量浓度为50-200g/L；
上述步骤(1)中所述聚己内酯的溶解分散时间为20-30h；
上述步骤(2)中所述碳纳米材料可以是单壁碳纳米管、多壁碳纳米管、石墨烯、氧化石墨烯等；
上述步骤(2)中所述的碳纳米材料质量浓度为1-10g/L；
上述步骤(3)中超声分散时间为1-2h；
上述步骤(4)中注射器针头选用18-23G平头针；
上述步骤(4)中电压设定为10-20kV；
上述步骤(4)中注射器移动速度设定为0.1-10mL/h；
上述步骤(4)中的芯纱可选用支数为20-40S的纯棉纱线、涤纶纱线或者手术缝合线等。
本发明的优越性：
该方法采用芯纱作为新型导电纤维的骨架，外包一层静电纺导电丝，这种方法改善了碳基纺丝的可纺性能，进而可将这种导电纱线用于织布和制作纺织品。新型导电纱线结合了碳基材料和芯纱骨架的特点，可广泛应用于智能穿戴纺织品、柔性传感装置、柔性电极等高新科技领域。
