【摘要】 通过将碳纳米管在棉无纺布基底上沉积制备了导电纳米复合涂层织物,研究了分散液离子强度对涂层织物导电性的影响。研究结果表明,当在海藻酸钠辅助分散的碳纳米管水溶液中添加浓度为0.1M·L^-1的氯化钠时,碳纳米管分散液的分散稳定性有所下降,同时织物表面涂层的沉积量大大增加,从而导致涂层织物的面电阻降低;当在织物表面循环组装5个周期时,面电阻值可以达到105Ω·sq^-1,与不添加氯化钠的溶液制备的织物相比,面电阻下降了33Ω·sq^-1,表明氯化钠的引入显著改善了涂层织物的导电性。更多还原

【Abstract】 The conductive nanocomposite coated fabrics were prepared by depositing the carbon nanotubes on the cotton nonwoven fabric substrate, and the effects of ionic strength of carbon nanotube dispersion solution on the conductivity of coated fabrics were studied. The results showed that when adding sodium chloride at a concentration of 0.1 M·L^-1 to the carbon nanotube solution dispersed by sodium alginate, the dispersion stability decreased. Meanwhile, the film deposition amount on the surface of the fabric increased greatly, which contributed to the decrease of sheet resistance of the coated fabric. When repeating the assembly for 5 times, the sheet resistance reached 105Ω·sq^-1, which had decreased by 33Ω·sq^-1 compared with the fabric prepared without the addition of sodium chloride. The result indicated that the addition of sodium chloride had significantly improved the conductivity of coated fabrics.更多还原
