Exploring Interactions and Properties of the Sodium Carboxymethyl Cellulose–Chitosan Biopolymer Complex.

The complex of sodium carboxymethyl cellulose (CMC) and chitosan (CH) in aqueous solution can be used for biomedical applications and is very beneficial for tissue engineering, drug delivery, and disease treatment. This article presents elaboration and properties of the complex of two polysaccharides with opposite charges of CMC/CH in aqueous solutions. The electrical conductivity under the influence of increasing concentrations of the CMC/CH mixtures from (0.5 to 10) g l−1 and increasing temperatures from 288.15 to 318.15 K is investigated. The reduced conductivities, σred$\left(\sigma\right)_{\text{red}}$, energy of activation ΔEσ$\Delta E_{\sigma}$, the Gibbs free energy of conductivity ΔGσred$\Delta G_{\text{σred}}$, and the activations parameters of the enthalpy (ΔHred$\Delta H_{\text{red}}$) and entropy (ΔSred$\Delta S_{\text{red}}$) are estimated.
