“…It is practically insolvable in ethanol but easy to be dissolved in hot or cold water which yielded with water a viscous colloidal solution. Na-CMC has received more attention owing to its low price (abundance), aptitude to form membranes, better biocompatibility, super water solubility, and swell susceptibility [2][3][4].…”

“…Alginates have favorable film-forming properties the thin layer in the alginate solution can eliminate the thin film of moisture by evaporation and is impermeable to oil and fat but can help them to redissolve in waterby-water vapor. The biocompatibility of sodium alginate has been evaluated broadly in vivo and in vitro which depends upon the alginate composition and purity level [4][5][6][7].…”

ABSTRACT. Biopolymers are referred to the bio-degradable polymer that is derived from living organisms in nature or synthesized from renewable materials but needs polymerization. There are consisting of monomeric units that bond together through a covalent bond to obtain large molecules. A biopolymeric blend of sodium carboxymethyl cellulose/sodium alginate (Na-CMC/SA) film was prepared by the casting/solvent evaporation method. In addition to the molecular structure, the optical and molecular geometry of the collected films were characterized. XRD of binary blend investigated the interaction and miscibility among two biopolymers. FTIR of the blend spectrum explicated the conferring of the two polymer group’s vibrations. UV/Vis and optical studies appeared a peak in the binary at the wavelength (227 nm) which explained the high combination between two polymers. Molecular geometry clarifies the assignment of vibrational spectra of pure polymers which implied the important role of the (C=O) group as eventful regions for the two polymers.

This paper presents the effect of salt concentration on the electrochemical, thermal, and structural properties of the solid polymer electrolyte (SPE) prepared with the polymer sodium carboxymethylcellulose (NaCMC) and the salt sodium triflate (NaCF3SO3). The electrolyte was prepared in the form of membranes using solution cast technique. Deionized water was used as a common solvent for both the precursor materials. The membranes were characterized using electrochemical impedance spectroscopy (EIS), Fourier‐transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD), and differential scanning calorimetry (DSC). XRD results show reduction in crystallinity of the electrolyte with an increase in the salt concentration. The FTIR result confirms polymer‐salt interaction. The ionic conductivity of the electrolyte membrane was found to be dependent on the concentration of NaCF3SO3. The maximum ionic conductivity of the SPE membranes was observed to be 1 × 10−4 Scm−1 at room temperature (36°C). DSC results show an increase in glass transition temperature (Tg) with increasing salt concentration. The total ionic transference number of the highest conducting sample was found to be ~1, which shows that the conductivity of SPE membranes is predominantly due to the transport of ions.

The presented work sheds light on the impact of CeO2 content and sintering temperatures on the microstructure and physical characteristics of Soda-Lime-Alumino Silicate Glass Ceramics for possible use in dental applications. Samples of nominal composition 45SiO2-15Al2O3-(20-x)NaO2-(20-x)CaO-2xCeO2, (x = 1–5) were successfully synthesized via the sol–gel technique. Synthesized samples were characterized by Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy, X-ray diffraction scan (XRD), and Scanning electron microscopy (SEM) supplemented with an EDX and calculate roughness parameters in addition to physical properties such as (density, free volume, oxygen packing density, etc.). XRD reveals that 850 °C is the optimal temperature to transform samples to their corresponding glass–ceramic derivative, leading to the rearrangement of Qn Si in the glass network. The rearrangement was explained through FTIR, Raman, and the surface morphology of samples. In addition, the increased density is attributed to the high compactness of the glass ceramic formed resulting from the addition of CeO2, which improves the durability and hardness of the samples.
