Abstract: The purpose of this work is to investigate the effect of the addition of salts in the form of calcium chloride CaCl2) and potassium chloride (KCl) on the rheological and conductometric properties of diluted sodium carboxymethylcellulose (NaCMC) dispersions. We created mixtures of sodium carboxymethylcellulose and salts (NaCMC/salts). Sodium carboxymethylcellulose (NaCMC) is a water-soluble polymer known for its biocompatibility, film-forming properties, and ability to form viscoelastic networks in solution. The incorporation of inorganic salts, such as calcium chloride and potassium chloride, profoundly modifies these properties due to electrostatic interactions between the ions and the carboxylate groups of the polymer. This study aims to better understand how the nature and valence of cations simultaneously influence the viscosity and conductivity of NaCMC/salts solutions. By varying the volume fraction f of the salts, we can open the way to potential applications in the biomedical and pharmaceutical fields, such as transdermal patches, controlled drug release systems, or polymer electrolytes.
