Conductimetric study of biodegradable CMC/MMT nanocomposites for paramedical applications

Biodegradable biopolymer-clay nanocomposites have attracted increasing interest for paramedical applications due to their biocompatibility and tunable physicochemical properties. In this work, a conductimetric study of aqueous systems based on sodium carboxymethylcellulose (CMC), montmorillonite clay (MMT), and their composites (CMC/MMT) is presented. The electrical conductivity of the solutions was investigated as a function of concentration and temperature in the range of 15–50°C. The results reveal distinct conductive behaviours depending on composition, highlighting the role of polymer-clay interactions in governing ionic mobility. An energetic analysis based on the Arrhenius model was carried out to determine the activation energies associated with charge transport mechanisms. Overall, the composite system exhibits tailored conductivity profiles that can be optimized for biomedical devices such as wound dressings and controlled drug release systems.
