“…MC-MCNT fiber has also been shown in recent research [14] to have anions and cations that can be selectively detected by switching the potential range in aqueous electrolytes. Cellulose MCNT-forming fiber over electrospinning showed a sensor for different ions and ion concentrations in aqueous electrolytes [56]. Other research showed that MCNTs with cellulose could functionalize as a water sensor [57] or chemical vapor such as methanol and 1-butanol [58].…”

Microcrystalline cellulose (MC) with 50 wt.% multi-walled carbon nanotube (MCNT) composites is obtained through extrusion, forming MC-MCNT fiber. In this study, we concentrate on three different electrolytes in propylene carbonate (PC) which have the same anions (TF−, trifluoro-methanesulfonate CF3SO3−) but different cations, EDMI+ (1-ethyl-2,3-dimethylimidazolium), Li+ (lithium ion), and TBA+ (tetrabutylammonium). Cyclic voltammetry and square wave potential steps, in combination with linear actuation measurements in a potential range of 0.7 V to −0.2 V, were conducted. Our goal in this work was to establish a cation-selective actuator–sensor device capable of distinguishing different cations. The linear actuation of MC-MCNT fiber had its main expansion at discharge due to the incorporation of TF− in the MC-MCNT fiber with the cations. In the following order, TBA+ > EDMI+ > Li+ had the best stress, strain, charge density, diffusion coefficients, and long-term stability. Chronopotentiometric measurements revealed that the cations in the PC solvent can be differentiated by their ion sizes. Further characterization of the MC-MCNT fiber was completed using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and FTIR and Raman spectroscopy.

Composite filaments are of considerable interest in research due to their exceptional performance characteristics and broad applicability. In this study, highly electrically conductive composite filaments comprising cellulose nanofibrils (CNF) and silver nanowires (AgNWs) are carefully prepared, accompanied by the proposition of an integrated microwave‐microfluidic synthesis method for AgNWs. The proposed reaction system exhibits a remarkable capability for swift AgNW synthesis, with a space‐time yield of 1.2 × 104 g (h·m3)−1, approximately five times superior to that achievable through conventional batch reactor methodologies. The microwave‐assisted microfluidic synthesis of AgNWs introduces a novel aspect to the extensive research on 1D nanomaterials. The design of experiments and multi‐objective Bayesian optimization are integrated iteratively to converge toward the global optimum, aiming to enhance screening efficiency and achieve a balanced outcome by maximizing aspect ratio and minimizing size for AgNWs. The AgNWs synthesized under optimal conditions has a diameter of ≈50.4 nm and an aspect ratio of ≈555. Subsequently, they are integrated into composite filaments with CNF, resulting in electrical conductivity and tensile strength of the composite filaments at values of 8.35 × 105 S m−1 and 186 MPa, respectively, surpassing those reported in existing literature for other analogous materials.
