“…At 1065 cm −1 , 1326 cm −1 , 1417 cm −1 , 1603 cm −1 and 3442 cm −1 , corresponding to C-O-C bonding, O-H bonding, -CH 2 scissoring, COO- asymmetric and -OH stretching, the absorption bands of CMC can be seen. These results were found to be in good agreement with those reported by Saadiah et al., confirming the presence of cellulose and carboxymethyl groups which are the backbone of CMC ( Saadiah et al., 2019 ). At 849 cm −1 , 1093 cm −1 , 1376 cm −1 and 3326 cm −1 , corresponding to C-C bonding, C-O stretching, C-H wagging, and -OH stretching, the absorption bands of PVA can be observed.…”

“…In Figure 3 b, the peaks in the region between 1314-1619 cm −1 can be seen to correspond to the carboxylate and hydroxyl groups where the intensity of both peaks increased, as the ratio of CMC increased. Intermolecular hydrogen bonding for the CMC/PVA system occurs at the region assigned to the bonding of -OH and -COO functional groups for the complexation ( Saadiah et al., 2019 ). In Figure 3 c, it was noted that the addition of CMC led to the formation of hydrogen bonds of the hydroxyl groups, as crosslinking increased; thus, the absorption bands in the region 3200-3500 cm −1 were seen to get wider ( Shin et al., 2020 ).…”

“…Of the various types of anionic polyelectrolytes, CMCs exhibit great promise due to their biocompatibility, low-cost, and good film-forming ability ( Saadiah et al., 2019 ). A CMC molecule contains fixed negative charge carriers and mobile positive charge carriers ( Parman, 1983 ; Valappil et al., 2013 ).…”

The aim of this research is an evaluation of polyelectrolytes. In the application of zinc-iodine batteries (ZIBs), polyelectrolytes have high stability, good cationic exchange properties and high ionic conductivity. Polyelectrolytes are also cost-effective. Important component of ZIBs are cation exchange membranes (CEMs). CEMs prevent the crossover of iodine and polyiodide from zinc (Zn) electrodes. However, available CEMs are costly and have limited ionic conductivity at room temperature. CEMs are low-cost, have high stability and good cationic exchange properties. Herein, polyelectrolyte membranes prepared from carboxymethyl cellulose (CMC) and polyvinyl alcohol (PVA) are examined. It is seen that an increase in the ratio of PVA leads to enhanced ionic conductivity as well as increased iodine and polyiodide crossover. ZIBs using polyelectrolytes having 75:25 wt.% CMC/PVA and 50:50 wt.% CMC/PVA show decent performance and cycling stability. Due to their low-cost and other salient features, CMC/PVA polyelectrolytes prove they have the capacity for use as cation exchange separators in ZIBs.

A novel polymer host from carboxymethyl cellulose (cMc)/poly(N-isopropylacrylamide) (pnipAM) was developed for a high safety solid polymer electrolyte (SPE) in a zinc ion battery. Effects of the PNiPAM loading level in the range of 0-40% by weight (wt%) on the chemical, mechanical, thermal, and morphological properties of the CMC/PNiPAMx films (where x is the wt% of PNiPAM) were symmetrically investigated. The obtained CMC/PNiPAMx films showed a high compatibility between the polymers. The CMC/PNiPAM20 blend showed the greatest tensile strength and modulus at 37.9 MPa and 2.1 GPa, respectively. Moreover, the thermal degradation of CMC was retarded by the addition of PNiPAM. Scanning electron microscopy images of CMC/PNiPAM20 revealed a porous structure that likely supported Zn 2+ movement in the SPEs containing zinc triflate, resulting in the high Zn 2+ ion transference number (0.56) and ionic conductivity (1.68 × 10-4 S cm −1). interestingly, the presence of PNiPAM in the CMC/PNiPAMx blends showed a greater stability during charge-discharge cyclic tests, indicating the ability of pnipAM to suppress dendrite formation from causing a short circuit. The developed CMC/PNiPAM20 based SPE is a promising material for high ionic conductivity and stability in a Zn ion battery. With the environmental concerns and the limitation of fossil fuels as well as the growing energy demands, the rechargeable battery is one kind of renewable energy sources which is consecutively developed for a sustainable energy supply. In spite of the most promising technology of lithium-ion batteries (LIBs), the zinc ion battery is used as a compelling alternative battery chemistry to LIBs for energy storage system 1-3 owing to its low cost, abundance, inflammability, low toxicity, promising energy density and environmental friendlier 4,5. The utilization of metal-ion batteries as power sources has led to exhaustive research on electrolyte systems with high electrochemical performance. It plays a significant role in battery electrochemistry that is the medium for the movement of ions within the batteries. Recently, solid polymer electrolytes (SPEs) have interested raised attention and enhanced research efforts as a fascinating alternative electrolyte bridge to liquid polymer electrolyte (LPEs) due to a lot of benefits, i.e., high durability, high energy density, lightweight, great flexibility for cell design, inert towards the electrodes, overcome the limitation of solvent leakage and low volatility, reduce the cell assembly cost, and great electrochemical and thermal stability 6. Fundamentally, SPEs consist of a dissolution of metal salts, e. g. lithium and zinc salt, in a host polymer, which the hopping process is used to describe the metal ions movement along the amorphous phase of polymer after the salts dissociate by interaction with the polar group of polymer 7. To coordinate with ions, therefore, the host polymer must contain electron donor groups such as O, N, and S. Moreover, it should

Cold atmospheric plasma surface nanoengineered carboxymethyl cellulose hydrogels as oral ibuprofen carriers

Smart hydrogels comprising polyvinyl alcohol and carboxymethyl cellulose have been fabricated using a green crosslinker tetraethyl orthosilicate. The hydrogels were subjected to cold atmospheric plasma-treatment using pure Ar, pure NH 3 and a mixture of the two. Enhanced surface wettability was witnessed post-plasma treatment; irrespective of the plasma gas employed. An insignificant surface ageing of the hydrogels was marked upon exposure to air for 10 days. AFM analyses revealed the surface topographical changes at the nano level while the bulk attributes remained unaffected. The hydrogels displayed smart swelling features. The release of ibuprofen from the hydrogels in simulated gastric and intestinal fluids affirmed their potential towards oral colon-targeted drug delivery. The preliminary kinetics of drug release indicated the anomalous nature of drug transport mechanism. More so, drug release from plasma-treated hydrogels were predominantly governed by diffusion process rather than polymer chain relaxational process. The hydrogels demonstrated good biodegradability and could be efficaciously utilized as potential oral drug delivery candidates.
