摘　　要：将片层氧化石墨烯(GO)超声分散于1-烯丙基-3-甲基咪唑氯盐([AMIM]Cl)中,在80℃加入纤维素制备了具有适宜黏度、长时间保持稳定性能的GO/[AMIM]Cl导电墨水。将制备的导电墨水印刷于纯棉织物表面,形成了一种纤维素基材柔性电子元器件。通过LED小灯的测试及伏安循环法表征,结果表明制备的纤维素基材柔性电子元器件具有良好的导电性能且具备一定储电能力。热物性数据显示,纤维素基材柔性电子元器件的接触冷暖感为0.113 W/m,小于纯棉织物的0.3 W/m;热传导率为4.65×10^(-4) W/(cm·℃),小于热传导率为13.1×10^(-4) W/(cm·℃)的纯棉织物,说明GO/[AMIM]Cl导电墨水能提高纯棉织物的热物性。The sheet graphene oxide(GO)were ultrasonically dispersed in 1-allyl-3-methylimidazolium chloride([AMIM]Cl),and then GO/[AMIM]Cl conductive ink with suitable viscosity and stable performance for a long time was prepared by adding cellulose at 80℃.The conductive ink was printed on the surface of pure cotton fabric to form a cellulose substrate flexible electronic component.Through the test of LED small lamp and the voltammetry method,the results showed that the cellulose-based flexible electronic components prepared in this study have good electrical conductivity and a certain power storage capacity.The thermophysical data showed that the cold and warm contact feeling of the flexible electronic components of cellulose substrate was 0.113 W/m,which was less than 0.3 W/m of cotton fabric.The thermal conductivity was 4.65×10^(-4) W/(cm·℃),which was less than cotton fabric with a thermal conductivity of 13.1×10^(-4) W/(cm·℃).It showed that GO/[AMIM]Cl conductive ink could improve the thermal properties of pure cotton fabrics.
