A flexible, electrically conductive and low-cost composite sheet has been prepared combining multi-walled carbon nanotubes (MWCNTs) and cellulose pulp using simple solution mixing method. The uniform attachment of MWCNTs on to the cellulose fibres of the composites lead to a gradual decline of the sheet resistance with an enhanced electrical conductivity. The crystallinity of the composites is also found to be increased. The composites remain thermally stable up to 550 K as well as demonstrate improved flame retardancy. The conducting CNT networks of the composites are not disrupted even after 600 bending cycles, indicating almost no loss of conductivity. This conducting and flexible composite sheet can be used in different energy storage devices.

用于柔性技术的掺入碳纳米管的纤维素纳米复合片

使用简单的溶液混合方法将多壁碳纳米管 (MWCNT) 和纤维素纸浆结合在一起，制备了一种柔性、导电和低成本的复合片材。多壁碳纳米管均匀附着在复合材料的纤维素纤维上，导致薄层电阻逐渐下降，导电性增强。还发现复合材料的结晶度增加。复合材料在高达 550 K 的温度下仍保持热稳定性，并显示出改进的阻燃性。即使在 600 次弯曲循环后，复合材料的导电 CNT 网络也不会被破坏，表明几乎没有导电性损失。这种导电且柔性的复合片材可用于不同的储能设备。
