Boosting optical and electrical characteristics of polyvinyl alcohol/carboxymethyl cellulose nanocomposites by GNPs / MWCNTs fillers as an application in energy storage devices

Abstract

The goal of this study is to manufacture polyvinyl alcohol and carboxymethyl cellulose films containing graphene nanoplates (GNPs)/MWCNTs to improve optical, dielectric, and electrical properties. The interaction between blend chains and GNPs/MWCNTs is emphasized by x-ray diffraction (XRD) analysis.

Structural, optical, thermal, and dielectric properties of carboxymethyl cellulose/sodium alginate blend/lithium titanium oxide nanoparticles: Biocomposites for lithium‐ion batteries applications

“…[1][2][3] Therefore, these types of combinations can be used in various optoelectronic and discharge energy devices. [4][5][6][7] The spinel Li 4 Ti 5 O 12 NPs are cheap, environment friendly, 8,9 and has good lithium ions mobility as well as high lithiumion insertion/extraction with potential at 1.55 V. 10 Also, these NPs possess a high structure stability "zero-strain" in charge/discharge cycles and have the potency to reinforce the performance for secondary Li-ions batteries due to their short diffusion paths and high surface area. 11,12 Due to these novel physicochemical properties of Li 4 Ti 5 O 12 NPs, it has gained increasing importance to reinforce the performance PV cells, some semiconductor devices, catalysis, and next-generation Li + -batteries.…”

“…16,17 The increasing interest in biodegradables materials have aggravate the scientists to investigate widely as polymers electrolyte system 4,18 Different renewable resources of polymers are suitable to act as host polymers involving the watersoluble polymers CMC and SA. 6,16,19,20 The anionic CMC polymer, a cellulose derivative, was chosen as the primary polymer due to its cost-effectiveness, good biocompatibility, and biodegradability and nontoxicity. 13,16,21 The CMC structure consists of hydroxyl ( OH) and carboxylate (COO À ) groups, which provide reactions between the various dopants in the polymeric system.…”

“…13,16,21 The CMC structure consists of hydroxyl ( OH) and carboxylate (COO À ) groups, which provide reactions between the various dopants in the polymeric system. 6,13,21,22 Also, the natural CMC polymer is used in the mixing operation with SA because of its amorphous nature to raise the degree of amorphousity of the blend matrix that facilitates the ions mobility. The SA is the sodium salt of alginic acid, biocompatible, and biodegradable natural polymer, extracted from brown seaweed that grows in cold water regions.…”

“…Also, these groups are found exceedingly compatible with various nanofillers and dopants to frame the innovative nanocomposites and composites. 6,13,16,19 Ibrahim and El Salmawi 26 studied the effect of gamma rays on the morphological, thermal, and mechanical properties of CMC/SA blends. To the best of our knowledge, the Li 4 Ti 5 O 12 NPs-loaded CMC/SA matrix-based polymer nanocomposite samples have not been introduced yet, to explore their potential technological applications.…”

“…The preparation of nanocomposites based on polymer nanoceramic compounds has become increasingly attention because it yields new multifunctional‐flexible polymeric materials with high dielectric constant, low mass density, good processability, and excellent mechanical strength as well as low brittleness 1‐3 . Therefore, these types of combinations can be used in various optoelectronic and discharge energy devices 4‐7 . The spinel Li 4 Ti 5 O 12 NPs are cheap, environment friendly, 8,9 and has good lithium ions mobility as well as high lithium‐ion insertion/extraction with potential at 1.55 V 10 .…”
