Review Article About Gel Polymers and Their Applications

One of the important applications of hydrogels is agricultural applications, as there is a controlled release of nutrients from the hydrogel into the soil, which are fertilizers loaded on the hydrogel. A large part of the fertilizer added to the soil is lost through leaching, especially in highly porous soils, in chemical processes, heavy rains, etc. A number of different polysaccharides, such as chitosan, pectin and carboxymethyl cellulose have been used to prepare hydrogels as a fertilizer release system for soil revitalization. Many studies have been conducted in this field. For example, Agaba et.al indicated that moisture retention in a particular soil due to the hydrogel is necessary to create a forest. Planted Water affects soil properties such as aeration, temperature, nutrient transfer, water absorption and conversion, which affects plant growth. Dimitri et al investigated the applicability of cellulose-based hydrogels in three different formulations, i.e. crosslinked by carbodiimide, as a carrier for sustained and controlled release of water and as nutrients in arid and desert regions.

Texture of emulsion-filled pea protein-potato starch gels: Effect of processing conditions and composition

From a physicochemical perspective, foods like vegan cheese and meat analogues are complex multicomponent gels. The aim of this study was to investigate the effect of processing conditions and composition on the textural properties of multicomponent gels containing starch, pea protein isolate (PPI) and emulsion droplets. Mechanical properties were measured, and structural analysis was carried with CLSM and SEM. In the case of particle gels prepared with maize starch (MS), a higher shearing speed decreased Young's modulus, fracture stress and fracture strain due to break up of the starch granules. In polymer gels prepared with potato starch (PS), structure and mechanical properties were not much affected by processing conditions. The addition of emulsion droplets increased the Young's modulus of MS gels and decreased that of PS gels. In PS gels, the fracture stress decreased further for smaller oil droplets. The addition of emulsion droplets was also found to decrease adhesiveness, cohesiveness and chewiness, regardless of the matrix structure. With protein addition into PS gels, an increase in Young's modulus and a decrease in fracture strain were observed. These results show that processing conditions and composition can be used to modulate the physical properties of complex food systems.

Carboxymethyl Cellulose – Polyvinyl Alcohol Composite-Based Gel Polymer Electrolyte for Rechargeable Zn-Air Batteries

The high ionic conductivity, lower interfacial contact resistance, enhanced safety, non-toxicity, and biodegradability bring the gel polymer electrolytes (GPEs) as a prospective electrolyte for applications in high-energy density flexible Zn-air batteries (ZABs). The present study comprehensively optimizes the procedures to obtain carboxymethyl cellulose (CMC)–polyvinyl alcohol (PVA) composite-based GPEs holding a maximum KOH amount in the polymer matrix. Optimization of the GPE has been performed and demonstrated by an in-house-developed rechargeable ZAB cells using MnO2-based air cathode and Zn anode. The optimization parameters include the ratio of PVA:CMC, concentration of PVA-CMC in DI water, and thickness of the gel polymer electrolyte. Results show that a 4mm thick GPE prepared from a polymer membrane synthesized using PVA:CMC ratio of 5:2 at a concentration of 0.063 g ml−1 in DI water displayed the highest 6M KOH uptake, least charge transfer resistance of the device, higher discharge plateau, and 5–6 times more cycling compared to GPE made of PVA only. The “as-synthesized GPE” demonstrates high stability of GPE over 100h for a Zn-air battery device. The findings of this work shall speed up the development of Zn air batteries for applications as energy storage systems.

Investigation of rheological and filtration characteristics of sedimentary gel-forming compounds

In producing wells, complete wetting often occurs, during which most of the oil reserves in them remain unproductive. This feature is typical for various fields, as well as for the fields of Kazakhstan. In this case, the most reliable way to increase oil recovery is to limit oil recovery through the use of modern technologies and chemicals. This article discusses the type of technology that allows to increase the efficiency of processing the bottom of the well – the use of sedimentary gel-forming compounds – SRFC the basis of the SRFC technology is to reduce the permeability of the flushed zones in the bottom of the formation and reduce the degree of its heterogeneity. The effect of these formulations is based on the formation of an insoluble precipitate and a gel polymer in the pore space in the lower part of the layer, the specified precipitate and gel block or reduce the permeability of the intervals washed. In the article, as a result of experimental studies, an assessment of the physico-chemical properties of gel-forming compositions was carried out using statistical methods for processing values and analyzing data, in connection with which the rheological properties of sedimentation compositions were simulated, taking into account the composition and average concentrations of various components (polymer, alkali).

Microemulsion-Based Polymer Gels with Ketoprofen and Menthol: Physicochemical Properties and Drug Release Studies.

Ketoprofen is a non-steroidal, anti-inflammatory drug frequently incorporated in topical dosage forms which are an interesting alternatives for oral formulations. However, due to the physiological barrier function of skin, topical formulations may require some approaches to improve drug permeation across the skin. In this study, ketoprofen-loaded microemulsion-based gels with the addition of menthol, commonly known for absorption-enhancing activity in dermal products, were investigated. The main objective of this study was to analyze the physicochemical properties of the obtained gels in terms of topical application and to investigate the correlation between the gel composition and its mechanical properties and the drug release process. Microemulsion composition was selected with the use of a pseudoternary plot and the selected systems were tested for electrical conductivity, viscosity, pH, and particle diameter. The polymer gels obtained with Carbopol® EZ-3 were subjected to rheological and textural studies, as well as the drug release experiment. The obtained results indicate that the presence of ketoprofen slightly decreased yield stress values. A stronger effect was exerted by menthol presence, even though it was independent of menthol concentration. A similar tendency was seen for hardness and adhesiveness, as tested in texture profile analysis. Sample cohesiveness and the drug release rate were independent of the gel composition.

Influence of the Crosslinker Hydrophobicity on the Swelling Kinetics of Poly(Acrylic Acid) Microgels

AbstractSuperabsorbent polymer gels are widely used in commercial areas, such as in hygiene products. A key aspect in these and other applications is the gel swelling kinetics, and a key factor of influence on that is the hydrophobicity of the gel. This paper reports on the synthesis of superabsorbent polymer microgel particles with four differently hydrophobic crosslinkers: N,N’‐methylenebisacrylamide (MBAA), N,N’‐ethylenebisacrylamide (EBAA), N,N’‐propylenebisacrylamide (PBAA), and N,N’‐butylenebisacrylamide (BBAA). This work uses droplet‐based microfluidics to produce uniform and well‐defined microgel specimen and study the influence of the crosslinker hydrophobicity on the swelling kinetics. In particular, this work determines swelling constants and their dependencies on the temperature of the swelling medium as well as the activation energies of swelling in relation to the crosslinker hydrophobicity. This work finds two competing effects, leading to a narrow window in which the activation energy of the swelling of the microgels decreases with increasing crosslinker hydrophobicity.

Emu oil enriched nanostructured lipid carriers of lornoxicam burdened polymeric gel augmented drug delivery and assisted cartilage repairing in knee osteoarthritis: In-vitro and in-vivo studies

Lornoxicam (LRX) alleviates pain and inflammation associated with knee osteoarthritis (OAS). However, inadequate solubility, short half-life, and gastrointestinal side-effects on chronic use hinder the efficacy of LRX through oral route. Therefore, in present investigation, lornoxicam loaded nanostructured lipid carriers (LRX-NLCs) were scaled-up post optimization using hot homogenization method. The optimized F14 LRX-NLCs demonstrated particle size of 172.1 ± 2.0 nm with polydispersity index (PDI) of 0.293 ± 0.01, zeta (ζ) potential of −15.5 ± 1.21 mV, entrapment efficiency of 92.85 ± 0.25 % and drug release up to 18.9 ± 1.8 % at 3 h in addition to sustained release pattern throughout 24 h. Later, F14 LRX-NLCs were amalgamated with carbopol 940 LR gel as LRX-NLCs-Gel and evaluated for pH, spreadability, drug content, rheological behavior, texture properties, ex-vivo skin permeation and retention, and dermal distribution. Furthermore, pharmacodynamic studies of LRX-NLCs-Gel disclosed a substantial diminution in pain and inflammation in addition to amended radiographic and histopathological features in monosodium iodoacetate (MIA) induced OAS in Sprague Dawley rats. LRX-NLCs-Gel exhibited a remarkable decline in the levels of pro-inflammatory cytokines such as IL-1β, TNF-α, in addition to COX-2 in knee OAS. LRX-NLCs-Gel presented an epochal decrease in synovial hyperplasia, inflammation, and ameliorated cartilage structure. In addition, omega-3, omega-6, and omega-9 fatty acids enriched emu oil might have assisted in offering synergistic activity with LRX in cartilage repairing due to suppression of the proteolytic activity of MMP-2 and MMP-9. In conclusion, LRX-NLCs-Gel may be a prospective candidate for translating the product in to a clinically viable dosage form.

HPAM-Cr (III) Gel Syneresis in Bulk Volume

This paper explores the crucial factors influencing the stability of polymer gels utilized in oil well treatments, with a focus on the effects of polymer mixing time and concentrations of polymer and crosslinker. Operating within a practical constraint of a 30-minute mixing time in surface facilities, our findings reveal that incomplete polymer dissolution leads to gel segregation and substantial water release over extended aging at 50 ºC. Notably, a reduction in the crosslinker/ polymer ratio, achieved by lowering crosslinker concentration or increasing polymer concentration, proves effective in mitigating water release to as low as 0‒1% over 90‒185 h of aging. Furthermore, gels prepared in sea and reservoir brines exhibit superior stability compared to those in distilled water, suggesting that ion presence in brines counteracts the repulsion between charged polymer chains observed in distilled water. This study provides valuable insights for optimizing polymer gel formulations under time constraints.

Physicochemical and Biological Properties of Vancomycin-Containing Antibacterial Polysaccharide Gels for Biocomposite Bone Implant Impregnation.

Polymeric drugs containing up to 60% by weight of the antibiotic vancomycin were synthesized based on dextran carriers activated with epichlorohydrin. Vancomycin was covalently bound, involving the primary amino group of the molecule through the hydroxypropyl radical to the C6 position of the anhydroglucose units of the dextran main chain. Covalent binding is necessary to prevent spontaneous release of the antibiotic from the gel, thereby reducing the risk of bacterial multiresistance. Antibacterial depot gels were obtained from those polymers, containing up to 17.5% by weight of polysaccharide with a cross-linking density of q = 3-5 nodes per macromolecule for the deposition of another type of drugs not covalently bound to the polymer gel. They were used to coat the surface of the internal pores of biocomposite bone implants based on bovine cancellous bone used in orthopedics. The chemical structure of the polymer was studied using 13C NMR spectroscopy and matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry. The stiffness of the gels was evaluated by the values of the accumulation modulus G' = 170-270 kPa and the loss modulus G″ = 3.7-4.2 kPa determined on a rheometer. Their values are close to those typical for materials used to replace soft tissue in plastic surgery. The minimum inhibitory concentration of the gels against Staphylococcus aureus P209 depends on the antibiotic content in the polymer. It equals 2.5 mg/L for vancomycin we used and 100 mg/L for a polymer containing 50% by weight of covalently bound antibiotic. The cytotoxic concentration measured with cell culture HEK 293T exceeds 1200 mg/L in 24 h exposure. The release dynamics of drugs not covalently bound to dextran from the depot gel were studied using fluorescein as a model. The release time is independent of the gel density and lasts up to 6 days for a 2 mm thick layer. Both the gel and the bone implants impregnated with it maintained consistently high antibacterial activity throughout the experiment, up to its completion after 168 h, with the local concentration of the released antibiotic at the site of bacterial attack exceeding the therapeutic level by 200 times.

Voriconazole and Beauvercin Loaded Niosomal Mucoadhesive Nanogel as an effective Treatment for the Management of Oral Candidiasis

Oral candidiasis is a fungal infection, which affects the oral mucosa. The main causative agent of this is Candida albicans and as the literature indicates highest prevalence of Candida bloodstream infections in India. Most commonly azole derivatives such as miconazole, fluconazole, itraconazol etc. are used to manage the infection. However, their efficacy is compromised due to multidrug resistance. A new azole derivative voriconzole could be effective but its poor water solubility and bioavailability are seen as significant limitations. Its efficacy can be enhanced by combining it with beauvericin, a cyclic hexadepsipeptide with remarkable antifungal activity against candida. One study reported that combining of beauvericin with voriconzole reduce the MIC of voriconazole by 128th times. Furthermore the solubility and bioavailability were enhanced by loading both the drugs in niosomes. The niosomes were imcorporated into a polymeric mucoadhesive gel post statistically optimization by the Box-Behnken experimental design. The niosomes were subjected to evaluation for vesicular size, surface morphology, entrapment efficiency, drug release and zeta potential High entrapment efficiency was observed in the optimized noisome formulation F3 (89.89±0.64 % for voriconazole and 92.98±0.35 % for beauvericin) exhibiting cumulative drug release of 79.98±1.87 % for voriconazole and 69.17±1.98 % for beauvericin. The mucoadhesive gel was smooth, homogenious with desired pH and mucodhesion. The stability studies indicated that all the formulations are stable as evidence by no significant change in drug content over the time. These findings suggest that a niosmal mucoadhesive gel loaded with voriconazole and beauvericin is a good therapeutic delivery system for the effective treatment of oral candidiasis.

Interfacial fusion-enhanced 11 µm-thick gel polymer electrolyte for high-performance lithium metal batteries

In the pursuit of ultrathin polymer electrolyte (<20 μm) for lithium metal batteries, achieving a balance between mechanical strength and interfacial stability is crucial for the longevity of the electrolytes. Herein, 11 μm-thick gel polymer electrolyte is designed via an integrated electrode/electrolyte structure supported by lithium metal anode. Benefiting from an exemplary superiority of excellent mechanical property, high ionic conductivity, and robust interfacial adhesion, the in-situ formed polymer electrolyte reinforced by titanosiloxane networks (ISPTS) embodies multifunctional roles of physical barrier, ionic carrier, and artificial protective layer at the interface. The potent interfacial interactions foster a seamless fusion of the electrode/electrolyte interfaces and enable continuous ion transport. Moreover, the built-in ISPTS electrolyte participates in the formation of gradient solid-electrolyte interphase (SEI) layer, which enhances the SEI’s structural integrity against the strain induced by volume fluctuations of lithium anode. Consequently, the resultant 11 μm-thick ISPTS electrolyte enables lithium symmetric cells with cycling stability over 600 h and LiFePO4 cells with remarkable capacity retention of 96.6% after 800 cycles. This study provides a new avenue for designing ultrathin polymer electrolytes towards stable, safe, and high-energy–density lithium metal batteries.

An in-situ polymerization strategy for gel polymer electrolyte Si||Ni-rich lithium-ion batteries

Coupling the Si-based anodes with nickel-rich LiNixMnyCo1−x−yO2 cathodes (x ≥ 0.8) in the energy-dense cell prototype suffers from the mechanical instability of the Li-Si alloys, cathode collapse upon the high-voltage cycling, as well as the severe leakage current at elevated temperatures. More seriously, the cathode-to-anode cross-talk effect of transitional metal aggravates the depletion of the active Li reservoir. To reconcile the cation utilization degree, stress dissipation, and extreme temperature tolerance of the Si-based anode||NMC prototype, we propose a gel polymer electrolyte to reinforce the mechanical integrity of Si anode and chelate with the transitional cations towards the stabilized interfacial property. As coupling the conformal gel polymer electrolyte encapsulation with the spatial arranged Si anode and NMC811 cathode, the 2.7 Ah pouch-format cell could achieve the high energy density of 325.9 Wh kg−1 (based on the whole pouch cell), 88.7% capacity retention for 2000 cycles, self-extinguish property as well as a wide temperature tolerance. Therefore, this proposed polymerization strategy provides a leap toward the secured Li batteries.

Effect of Fluorine Segments in Fluoropolymer matrix on the Properties of Gel Polymer Electrolytes

Polymer quasi‐solid electrolytes have been paid widely attention in account of their outstanding advantages in safety, flexibility, viscoelasticity and film formation. Fluoropolymer is used as matrix of gel electrolytes not only has high electrochemical stability, but also facilitates the dissociation of lithium salts owning to the strong electron‐absorbing C‐F groups, which makes it a very promising choice for the further development of gel electrolytes. Due to the different sites of C‐F bonds, their activity is also diverse, which results in the difference of the mobility of lithium ions and the LiF composition of SEI film on the surface of lithium metal anode. As a result, distinct fluorine‐containing gel polymer electrolytes are prepared by in‐situ polymerization of two different monomers, HFMA and TFMA. Compared with ‐CF3 on terminal group in TFMA, the gel electrolyte polymerized with HFMA whose C‐F group with stronger electronegativity is at the intermediate carbon site, as polymer matrix has better performance. The ionic conductivity achieves 7.02×10−3 S cm−1 at room temperature, and the assembled batteries have a capacity retention rate of 91% after 200 cycles of 1 C. Our research has laid a solid theoretical foundation for the further development of quasi‐solid electrolyte.

Internally connected porous PVA/PAA membrane with cross-aligned nanofiber network for facile and long-lasting ion transport in zinc–air batteries

In response to the growing interest in next-generation wearable devices, the demand for high-performance, safe, and flexible power sources has increased. Flexible zinc–air batteries (ZABs) based on gel polymer electrolytes (GPEs) have emerged as promising candidates for wearable power sources owing to their high energy density, safety, and cost efficiency. However, persistent electrolyte evaporation through the air cathode poses a significant challenge, resulting in poor lifespan characteristics that impede practical applications. In this study, we developed a polymer composite-type GPE composed of cross-aligned nanofibers (NFs) of a polyacrylic acid (PAA)-based framework embedded in a polyvinyl alcohol (PVA) matrix. Upon immersion in a liquid electrolyte (6 M KOH), the superabsorbent PAA spontaneously generated an internally connected porous (IP) structure adjacent to the aligned PAA NFs. These pores served as directional water channels, facilitating rapid hydroxide ion conduction and yielding a remarkable ionic conductivity of 235.7 mS cm−1. The PVA matrix acts as both a packaging material and the main body of the GPE, providing good dimensional stability and mitigating the swelling of PAA, even under conditions of high electrolyte uptake, while also ensuring high flexibility. The IP-PVA/PAA composite GPE demonstrated a high power output, rate performance, and excellent lifespan in flexible ZABs. Furthermore, successful operation at various bending angles provides empirical evidence supporting the viable application of flexible ZABs.

Investigation of Carbonation Kinetics in Carbonated Cementitious Materials by Reactive Molecular Dynamics Simulations.

Calcium carbonate (CaCO3) precipitation plays a significant role during the carbon capture process; however, the mechanism is still only partially understood. Understanding the atomic-level carbonation mechanism of cementitious materials can promote the mineralization capture, immobilization, and utilization of carbon dioxide, as well as the improvement of carbonated cementitious materials' performance. Therefore, based on molecular dynamics simulations, this paper investigates the effect of Si/Al concentrations in cementitious materials on carbonation kinetics. We first verify the force field used in this paper. Then, we analyze the network connectivity evolution, the number and size of the carbonate cluster during gelation, the polymerization rate, and the activation energy. Finally, in order to reveal the reasons that caused the evolution of polymerization rate and activation energy, we analyze the local stress and charge of atoms. Results show that the Ca-Oc bond number and carbonate cluster size increase with the decrease of the Si/Al concentration and the increase of temperature, leading to the higher amorphous calcium carbonate gel polymerization degree. The local stress of each atom in the system is the driving force of the gelation transition. The presence of Si and Al components increases the atom's local stress and average charge, thus causing the increase of the energy barrier of CaCO3 polymerization and the activation energy of carbonation.

Ultraviolet-cured heat-resistant and stretchable gel polymer electrolytes for flexible and safe semi-solid lithium-ion batteries

Lithium-ion (Li-ion) batteries assembled with gel polymer electrolytes (GPEs) are predicted to increase battery energy density while maintaining battery safety. In this work, poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) is successfully used as a polymer matrix to prepare a new kind of GPE (PHHNT) by ultraviolet (UV) curing technology. The polymer network structure formed by photopolymerization technology significantly enhances the tensile properties of the electrolyte. Lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) improves the concentration and transport efficiency of lithium ions in the electrolyte as well as the ionic conductivity (1.22 × 10−3 S cm−1) of the GPEs. In addition, the unique tubular structure of the halloysite nanotube (HNT) and the opposite charges carried by the inner and outer surfaces provide additional channels for the lithium salt and facilitate its dissociation. This enhances the expedited movement of Li+ inside the electrolyte, while simultaneously improving the electrochemical and thermal durability of the electrolyte. The assembled LiFePO4 (LFP)/PHHNT/Li battery has an initial discharge-specific capacity of 140.5 mAhg−1 at a current density of 0.5C, showing a high capacity retention rate of 89 % after 120 cycles. The design of this composite material significantly improves the overall performance of the electrolyte and is more suitable for flexible and safe solid-state Li-ion batteries.

High-voltage (> 3 V) energy storage device based on sputter-grown TiCrN microelectrodes towards miniaturized applications

In this work, we report sputter-grown micro-patterns of titanium chromium-based bimetallic nitride (TiCrN) over Si/SiO2 substrate. The highly stable TiCrN-micro pattern is tested electrochemically and used to construct an efficient microsupercapacitor (MSC) device. To achieve a stable and high-voltage window, a non-aqueous gel polymer electrolyte (GPE) of TEABF4/EC/PC/PVDF is optimized. At room temperature, the GPE exhibits high ionic conductivity of ~10.58 mS cm−1 with exceptional mechanical stability. A symmetric supercapacitor based on TiCrN sandwich structure (TiCrN-SS) is fabricated with TEABF4 GPE for practical application. The TiCrN-SS device works on a high voltage of 3.1 V and exhibits good electrochemical properties. The device shows a high energy density of 1.9 μWh cm−2 (5.9 Wh kg−1) at a power density of 109 μW cm−2 (0.34 kW kg−1). To utilize the excellent performance of TiCrN-SS as a miniaturized power source, an on-chip MSC is subsequently fabricated by patterning planar interdigitated TiCrN-microelectrodes. The constructed on-chip TiCrN microsupercapacitor (TiCrN-MSC) works on a wide voltage window of 0–3.1 V while maintaining an optimum areal capacitance of ~500 μF cm−2 at 0.07 mA cm−2 current density. The device exhibits an areal energy density of ~0.7 μWh cm−2 with an optimum 169.02 μW cm−2 power density. This remarkable electrochemical performance and exceptionally wide voltage window of TiCrN-based MSC makes it a potential candidate for direct use as a miniaturized power source in microelectronic devices.

Technical Notes: Robustness of three-dimensional treatment and imaging isocenter testing using a new gel dosimeter and kilovoltage CBCT.

Coincidence of the treatment and imaging isocenter coordinates is required to safely perform small-margin treatments, such as stereotactic radiosurgery of multiple brain metastases. A comprehensive and direct methodology for verifying concordance of kilovoltage cone-beam computed tomography (kV-CBCT) and treatment coordinates using an x-ray CT-based polymer gel dosimeter (dGEL) and onboard kV-CBCT was previously reported. Using this methodology, we tested the ability of a new commercially available x-ray CT-based polymer dGEL with a rapid response to provide efficient quality assurance (QA). The aim of this study was to evaluate the robustness of the three-dimensional geometric QA methodology using dGEL. The dGEL were commercially manufactured. The prescribed dose for each field was determined by visually identifying the 5, 10, and 20Gy isodose lines. A linear accelerator was used to irradiate the gels with seven non-coplanar beams. An in-house analysis program was used to identify the beam axes and treatment isocenter in kV-CBCT coordinates by processing the pre- and post-irradiation CBCT images. The impact of the radiation dose on the test reproducibility was examined, and the detectability of an intentional geometric error was assessed. The treatment isocenter was within 0.4mm of the imaging isocenter for all radiation doses. The residual error of the test with the intentional error was within 0.2mm. The analysis and image quality variations for a single dGEL introduced displacement errors less than 0.3mm. The test assessed the coincidence of treatment and kV-CBCT isocenter coordinates and detected errors with high robustness. Even for a 10Gy dose, the test yielded results comparable with those obtained using higher radiation doses owing to the rapid response of the dGEL dosimeter.

Rational design and elucidation of interfacial dynamics in PMMA/PVDF compatibilized blends through solution blending for stable quasi-solid-state dye-sensitized solar cells

In the photovoltaic market, the widespread adoption of traditional dye-sensitized solar cells (DSSCs) faces obstacles due to inherent stability challenges. The solution to these issues involves replacing liquid electrolytes with quasi-solid electrolytes. In this work, quasi-solid state electrolytes were synthesized by employing a polymer blend and inorganic salt. The polymeric blends, comprising polymethyl methacrylate (PMMA) and polyvinylidene fluoride (PVDF), were meticulously prepared through the solution blending technique. The investigation of blend compatibility, crystallinity, and stability involved analyses through differential scanning calorimetry (DSC), scanning electron microscopy (SEM), X-ray diffraction (XRD), and UV-degradation assessments, respectively. The findings indicated that the concentration of ingredients significantly influenced the compatibility, crystallinity, and stability of the blends. The compatibilized blend was employed in crafting polymer gel electrolytes (PEGs), demonstrating that both the concentration and type of salts significantly influence the ionic conductivity of PEGs. The highest conductivity, reaching 2 mS/cm, was achieved with a mixed salt concentration of 50w%/50w% (NH4I/KI). Subsequently, this electrolyte was incorporated into the fabrication of quasi-solid state DSSC. The results showed that the DSSC with PEG achieved 2.81 % efficiency, while the traditional DSSC had 4.11 % efficiency. Notably, after fifteen days, the efficiency of the traditional DSSC dropped to 0.20 %, while the PEG-based DSSC remained stable (2.58 %).
