Abstract A large amount of short and waste protein fibres, including silk and wool generated during fibre processing that is not spinnable, eventually ends up in the landfill. Here we are reporting on using these waste materials for fabrication of conductive composite. We prepared Nickel (Ni) doped textile-based conductive composites from silk, and wool waste fibres in powder forms and graphene oxide (GO), for the first time, by bulk synthesis method. The infrared spectroscopy revealed that the silk and wool formed composites with graphene oxide and Ni. The obtained Ni-doped graphene/protein fibres composites after carbonisation showed a honeycomb structure with high surface area and pore volume. The conductivity of the Ni-doped composites was higher than the undoped composites. Considering the surface area, pore volume and conductivity results, there is a huge potential for the fabricated material from biobased to use as an electrode material.

来自天然蛋白质纤维废料的导电蜂窝结构石墨烯复合材料

摘要 纤维加工过程中产生的大量不可纺的短纤维和废弃蛋白质纤维,包括丝绸和羊毛,最终都会进入垃圾填埋场。在这里,我们报告了使用这些废料制造导电复合材料的情况。我们首次通过批量合成方法从粉末形式的丝绸和羊毛废料纤维和氧化石墨烯 (GO) 中制备了镍 (Ni) 掺杂的纺织品基导电复合材料。红外光谱显示,丝绸和羊毛与氧化石墨烯和镍形成复合材料。碳化后获得的Ni掺杂石墨烯/蛋白质纤维复合材料显示出具有高表面积和孔体积的蜂窝结构。Ni掺杂复合材料的电导率高于未掺杂复合材料。考虑表面积、孔体积和电导率结果,
