摘 要: | 多功能柔性二氧化锰/还原氧化石墨烯碳化棉织物(MnO_2/rGO@C)在本文中得以制备。为赋予棉织物多重功用,先将棉织物浸于GO分散液中,然后采用原位溶液沉积法将纳米MnO_2粒子结合于GO-棉织物表面,并通过碳化工艺获得最终多功能导电碳化产品。采用SEM,XRD,ICP测试和元素分析对碳化织物的微观结构形态及组成成分进行表征,并就其电-化学性能和电-机械性能进行评估与研究。结果显示,在电流密度为100 mA/g时,MnO_2/rGO@C的比电容可达329.4 mA h/g,比未经MnO_2/rGO整理的碳化纯棉织物高40%以上。此外,MnO_2/rGO@C还展现出优良和可重复的电-机械性能,应变恒定,在曲率为0.6cm-1时,其标准电阻(RR0)/R0可达0.78。MnO_2/rGO@C织物用途广泛,可规模化生产,并能适应多种智能纺织品的应用。

Abstract: | Versatile ductile reduced graphene oxide/manganese dioxide cotton fabric (MnO2/rGO@C) was prepared.In order to make the cotton fabric versatile,it was firstly soaked in GO dispersion,nano-particles and MnO2 were then combined on the surface of GO-cotton fabric by adopting in-situ solution deposition method,and the final versatile conductive carbonized product was got through carbonization process.The micro-structure and components of carbonized fabric were characterized by SEM,XRD,ICP test and element analysis,and their electrochemical property and electromechanical property were evaluated and investigated.The results showed that the capacitance of MnO2/rGO carbonized cotton fabric (MnO2/rGO@C) was 329.4mA h/g when the electric current density was 100mA/g,which was more than 40% higher than that of the carbonized cotton fabric without MnO2/rGO finishing.In addition,MnO2/rGO@C had showed good and repeatable electromechanical property,its standard resistance (R-R0)/R0 could reach 0.78 at a constant strain (curvature=0.6cm-1).The MnO2/rGO@C fabric was versatile and it could be produced at a large scale and was suitable for multiple smart textile applications. |
