Description
Summary:In this work, cotton fabric (Ct) impregnated with nanocellulose (NC) was used to create an environmentally friendly, biocompatible and biodegradable elastic and water-repellent smart textile. For its manufacture, an inexpensive nanocellulose hydrogel was obtained by the method of TEMPO-mediated oxidation of an organosolv pulp from stalks of non-wood widespread wild-growing perennial cereal common reed. Then, an 8 µm thick nanostructured layer of promising non-toxic and earth-abundant copper(I) iodide (CuI) thermoelectric semiconductor was deposited by the Successive Ionic Layer Adsorption and Reaction (SILAR) chemical solution method on the composite Ct/NC fabric. Thus, a smart Ct/NC/CuI thermoelectric textile was obtained. Studies of the crystal structure by X-ray diffractometry (XRD), chemical composition by X-ray fluorescence (XRF) microanalysis and energy-dispersive X-ray spectrometry (EDS), and surface morphology by scanning electron microscopy (SEM) confirmed high adhesion of NC to Ct, good absorption of NC by cotton fiber, and penetration of NC into the inner part of Ct fiber, which is important for strengthening and hydrophobization of cotton. Experimental measurements of the thermoelectric parameters of Ct/NC/CuI textile revealed a Seebeck coefficient of 115 μV/K, a conductivity of 4.96 S/cm, a thermoelectric power factor at near room temperatures of 6.56 μW/(m K 2 ), and a specific thermoelectric power 4.5 µW/cm 2 . These indicators of thermoelectric efficiency allow the Ct/NC/CuI textile obtained here to become the basis for an efficient body-heat-harvesting thermoelectric nanogenerator.
