“…The reported density for each aerogel was calculated by estimating the corresponding contribution of cellulose and CNTs on each aerogel as Hernández‐Varela et al 17 reported before. Then, porosity (P, %) of each sample was calculated using this following equation :

P (%) = (1 - \frac{ρ^{*}}{ρ}) \times 100

where (ρ*) is the experimental density, and (ρ) is the theoretical density of the aerogels calculated using the cellulose density (1.52 g/cm 3 ) and CNTs density (1.74 g/cm 3 ) reported elsewhere 34,35 and their respective mass fractions.…”

Facile, lightweight, and sustainable aerogels have been a growing interest in their applications as support matrixes in the current environmental and energy challenges. In this study, a cellulose aerogel (CA) is fabricated using a homogeneous dispersion of cellulose fibers in an alkali‐urea aqueous solution and a carbon nanotube ink (CNT‐ink) to increase its electrical and conductive behavior in a potentiometric analysis. The physicochemical and morphological properties of the resultant composite aerogels (CA, CA1, and CA2) are investigated by thermal, water resistance, mechanical, FTIR, and SEM analysis. The prepared material exhibits a structured solid network that is visualized through SEM in which fibers are functionalized with CNTs. The results from compressive tests reveal that CA2 has excellent mechanical properties. A saturated CA with CNT‐ink can turn on a white LED and potentiometric measurements by preparing an aerogel‐based ion‐selective electrode (CA2 ‐ ISE) with a potassium ion‐selective membrane (K+ − ISM) reveal good sensitivity at room temperature for the detection in a specific electrolyte solution.
