Sustainability of Multiwall Carbon Nanotube Fibers and Their Cellulose Composite

Nowadays, the research community envisions smart materials composed of biodegradable, biocompatible, and sustainable natural polymers, such as cellulose. Most applications cellulose electroactive are developed for energy storage sensors, while only a few reported linear actuators. Therefore, we introduce here cellulose-multiwall carbon nanotube composite (Cell-CNT) fibers compared with pristine multiwall (CNT) made by dielectrophoresis (DEP) in their actuation an organic electrolyte. Electrochemical measurements (cyclic voltammetry, square wave potential steps, chronopotentiometry) were performed electromechanical deformation (EMD) measurements. The Cell-CNT outperformed main at discharging, having 7.9 kPa stress 0.062% strain, making this more materials, textiles, or robotics. CNT fiber depends on scan rates switching from mixed to expansion negative charging. fiber-specific capacitance was much enhanced 278 F g−1, had capacity retention 96% after 5000 cycles, than fiber. samples characterized scanning electron microscopy (SEM), BET (Braunauer-Emmett-Teller) measurement, dispersive X-ray (EDX) spectroscopy, FTIR, Raman spectroscopy.
