The Effect of Changing the Weights of Zinc Oxide Nanoparticles and Weights of Sodium Chloride on Some Physical Properties of Carboxymethylcellulose Thin Films

The objective of this work is to improve certain physical properties of the polymer carboxymethylcellulose (cmchv). the samples were prepared by adding sodium chloride and zinc oxide nanoparticles to cmchv solutions at different weights (0.00, 0.75, 1.50, 2.25, 3.00 g). when samples are exposed to heat, they do not become liquid or evaporate, but instead ignite and burn. the elasticity of the samples increased with increasing weights of the materials added to them, but the elasticity increased more with increasing weights of sodium chloride than with increasing weights of zinc oxide nanoparticles. the decrease in the transmission spectrum of the samples with increasing weights of sodium chloride and zinc oxide nanoparticles indicates that the opacity of the samples increases with increasing weights(as in the sample containing 3 grams of sodium chloride or zinc oxide nanoparticles).
