The dependence of NC indicators on the technological parameters of its production in the environment of sulfuric acid and 2,2,6.6-tetramethylpiperidine-1-oxyl (TEMPO) was established. It is shown that an increase in the concentration of reagents, temperature and duration of processes leads to an increase in the density, transparency and physical and mechanical parameters of NC films. The dependence of the physical and mechanical parameters of the packaging paper on the consumption of NC has been established. The characteristics of cellulose and NC from NDRS were investigated by SEM, FTIR, TEM, AFM, XRD, TGA. The regularities of the influence of technological parameters on the main physical properties of thin-film structures from NC have been determined, and their characteristics have been determined. On the basis of nanocellulose, moisture sensors and bending sensors, light-sensitive material in the photodetector of the photoresistive type, coating with a high sun protection factor, thermoelectric module for use in a wearable thermoelectric generator have been synthesized. Regulatory and technical documentation for the production of composite materials based on cellulose and nanocellulose has been developed Product Description popup.authors Barbash Valerii Anatoliyevich Galish Vita V.
