“…Finally, that broadband at 3250 cm −1 can be ascribed to stretching vibration of the O-H groups associated with absorbed moisture [38]. The FTIR spectra also confirmed the alginate structure as all characteristic peaks were observed at 1015, 1400, and 1600 cm −1 which are attributed to glycoside bond (C-O-C), symmetric stretching of -COO−, and antisymmetric stretching of -COO−, respectively [39]. Regarding the aerogels (Figure 2B), there was no clear difference between all the spectra, in which prominent bands at 1000, 1300, 1400, 1600, 1740, 2900, and 3000-3500 cm −1 represent -C-H stretching, aromatic skeletal vibration, -C-O vibration, -OH bending, -C=O-linkage, -CH-stretching, and OH-stretching, respectively [7].…”

Aerogels are 3-D nanostructures of non-fluid colloidal interconnected porous networks consisting of loosely packed bonded particles that are expanded throughout their volume by gas and exhibit ultra-low density and high specific surface area. Cellulose-based aerogels can be obtained from hydrogels through a drying process, replacing the solvent (water) with air and keeping the pristine three-dimensional arrangement. In this work, hybrid cellulose-based aerogels were produced and their potential for use as dressings was assessed. Nanofibrilated cellulose (NFC) hydrogels were produced by a co-grinding process in a stone micronizer using a kraft cellulosic pulp and a phenolic extract from Maclura tinctoria (Tajuva) heartwood. NFC-based aerogels were produced by freeze followed by lyophilization, in a way that the Tajuva extract acted as a functionalizing agent. The obtained aerogels showed high porosity (ranging from 97% to 99%) and low density (ranging from 0.025 to 0.040 g·cm−3), as well a typical network and sheet-like structure with 100 to 300 μm pores, which yielded compressive strengths ranging from 60 to 340 kPa. The reached antibacterial and antioxidant activities, percentage of inhibitions and water uptakes suggest that the aerogels can be used as fluid absorbers. Additionally, the immobilization of the Tajuva extract indicates the potential for dentistry applications.

“…The preparation of alginate-GA BBPEs is done by using the previous reported work. [15,16] For the preparation, 2 g of alginate and 20 wt.% of GA was dissolved in distilled water, and then, different composition (2 to 10 wt.%) of EC were added into the alginate-GA solution. The mixture was stirred until homogenous solution was obtained and then was poured into a petri dish.…”

In this present work, the study of ionic conductivity based on bio‐based polymer electrolytes (BBPEs) containing with alginate doped glycolic acid (GA) and plasticized with ethylene carbonate (EC) is presented. The ionic conductivity of present work is determined through impedance spectroscopy over a frequency range from 50 Hz to 1 MHz. The addition of EC has improved the Cole‐Cole plot for entire samples where it revealed the combination of CPE and bulk resistant in series for their electrical equivalent circuit. It is shown that the ionic conductivity increased from 10−5 to 10−4 S cm−1 upon addition of plasticizer into BBPEs system with the optimum conductivity is obtained at 9.06 × 10−4 S cm−1 for sample containing 6 wt.% of EC. The findings show that the present system has great potential to be used in application of polymer electrolytes system.

“…The utilization of natural polymers which are biodegradable, abundant, biocompatible, and low cost to be preferred. [ 6,7 ] Some of the natural polymers used as polymer electrolyte such as starch, cellulose, and its derivative, [ 7 ] chitosan, alginate, [ 8 ] and rubber. Cellulose is an important structural component in higher plants and is the most abundant polymer on earth which is produced as much as 1.5 × 10 12 tonnes per year from biomass.…”

“…Through the polymer blend technique, the ion conduction process takes place more easily because it provides many transit groups for ions. [ 12 ] To increase the ionic conductivity, several approaches have been taken, including the use of polymers with different chain lengths, copolymers, [ 13 ] plasticizers, [ 8,14 ] and polymer‐ceramic composites. [ 15 ] Several polymer electrolytes have been successfully designed using MC and CMC such as MC/ Chitosan [ 12 ] and CMC/CMKC.…”

This work aims to study the influences of 1‐ethyl‐3‐methylimidazolium acetate, [EMIm]Ac ionic liquid incorporation with various weight percentage to the characteristics of biopolymer blend electrolytes (BBEs) based on methyl cellulose/carboxymethyl cellulose (MC/CMC) (50/50) blend, i.e., the ionic conductivities, crystallinities, mechanical properties, surface morphology, and thermal stability. [EMIm]Ac ionic liquid is synthesized using a metathesis reaction between [EMIm]Br and CH3COOK in methanol solvent, while the BBEs preparation is conducted using casting solution technique. The functional groups and molecular structure of BBEs samples are confirmed by using Fourier transform infra red (FTIR) and nuclear magnetic resonce (NMR), while the characteristics of ionic conductivities, mechanical properties, crystallinities, surface morphology, and stability thermal are conducted using electrochemical impedance spectroscopy, tensile tester, X‐ray diffraction (XRD), scanning electron microscopy, and thermogravimetry analysis/differential thermogravimetry (TGA/DTG). The [EMIm]Ac ionic liquid incorporation greatly affects the characteristics of BBEs with optimum condition at the 15% [EMIm]Ac ionic liquid incorporation with a value of 1.53 × 10−2 S cm−1, 20.83 MPa/21.57%, and 217.24–356.34 ℃ for ionic conductivity, tensile strength/elongation at break, and decomposition temperature, respectively. The optimum condition from this study fulfills the standard minimum requirement for a lithium‐ion battery separator.
