The influence of fibre type and dipping cycle on the graphene oxide (GO) add-on and the resultant mass-specific resistance has been studied for different fibres. Seven commonly used fibres, viz cotton, viscose, silk, wool, nylon, acrylic and polyester, are selected for the study. A comparative evaluation of GO add-on and the resultant mass-specific resistance of all these fibres are carried out under similar process conditions. Fibres are treated separately with 1% w/v GO solution up to 10 consecutive dipping cycles. Graphene oxide enriched fibres are reduced with sodium dithionite to restore graphene structure. Use of fibre as substrate for experiment eliminates the effect of other structural parameters of either yarn or fabric form. FTIR and UV-vis spectra confirm successful exfoliation of graphite to GO. FTIR study reveals significant chemical interaction of GO with cotton, viscose, nylon, and silk. SEM micrographs show that the graphene sheets are uniformly deposited on the cotton, silk, and nylon. Cotton yields maximum GO add-on and acrylic yields the lowest in all dipping cycles. Lowest mass-specific resistance is obtained in case of cotton, while highest values are obtained in case of acrylic after 10 dipping cycles. Nylon needs lowest amount to GO to achieve the same level of conductivity.

纤维类型和浸渍周期对石墨烯吸附和纤维导电性的影响

已经针对不同的纤维研究了纤维类型和浸渍周期对氧化石墨烯 (GO) 添加剂的影响以及由此产生的质量比电阻。研究选择了七种常用纤维，即棉、粘胶、丝绸、羊毛、尼龙、腈纶和涤纶。在类似的工艺条件下，对 GO 附加物和所有这些纤维的最终质量比电阻进行了比较评估。纤维用 1% w/v GO 溶液单独处理最多 10 个连续浸渍循环。用连二亚硫酸钠还原富含氧化石墨烯的纤维以恢复石墨烯结构。使用纤维作为实验的基材消除了纱线或织物形式的其他结构参数的影响。FTIR 和 UV-vis 光谱证实石墨成功剥离为 GO。FTIR 研究揭示了 GO 与棉花、粘胶纤维、尼龙和丝绸的显着化学相互作用。SEM 显微照片显示石墨烯片均匀地沉积在棉花、丝绸和尼龙上。在所有浸渍循环中，棉花产量最高，而丙烯酸产量最低。在棉花的情况下获得最低的质量比电阻，而在 10 次浸渍循环后获得最高的值。尼龙需要最低的 GO 量才能达到相同水平的导电性。而最高值是在 10 次浸渍循环后获得的丙烯酸树脂。尼龙需要最低的 GO 量才能达到相同水平的导电性。而最高值是在 10 次浸渍循环后获得的丙烯酸树脂。尼龙需要最低的 GO 量才能达到相同水平的导电性。
