石墨烯整理蚕丝织物的导电性能

为获得耐水洗和高导电的纺织材料，采用原位还原法将氧化石墨烯(GO)用于蚕丝织物的导电整理。探究了GO 质量浓度、GO 溶液pH 值、还原剂用量、超声时间和十二烷基苯磺酸钠质量浓度等对蚕丝织物导电性能的影响，分析了还原氧化石墨烯(rGO)导电蚕丝织物的导电耐久性，并借助扫描电子显微镜对织物形貌进行表征。结果表明：在GO 质量浓度为15 g/ L，GO 溶液pH 值为5，还原剂质量浓度为5 g/ L，超声时间为30 ~ 60 min 时，采用原位还原法还原吸附GO 并烘干的蚕丝，其表面电阻值降低至1. 372 kΩ/ cm，导电性优良；蚕丝表面被GO 完全覆盖，经20 次水洗或机械摩擦后蚕丝织物依然保持较好的导电性能。

Electrical conductivity of silk fabrics finished with graphene

In order to obtain washable high-conductivity textile materials, graphene oxide (GO) was used for the electrical conductive finishing of silk fabric by in-situ reduction. The influence of concentration of GO, pH value of GO solution, dosage of reducing agents, ultrasonic time and concentration of sodium dodecyl benzene sulfonate on the conductivity of the silk fabric was discussed. The conductive durability of the reduced graphene oxide (rGO) conductive silk fabric was analyzed, and the morphology of the silk fabric was characterized by scanning electron microscope. The results show that under the condition of GO of 15 g/ L, pH value of 5, reductant of 5 g/ L, ultrasonic treatment time of 30 -60 min, the surface electric resistance of silk subjected to in-situ reduction is reduced to 1. 372 kΩ/ cm, and the conductivity of rGO coated silk fabric is excellent. The surface of silk is covered by GO sheets completely, and the surface electric resistance of the silk fabric is slightly changed after 20 times of standard washing or mechanical rubbing.
