“…For instance, hydrogels composed of oppositely charged gelatin (cation) and chondroitin sulfate (anion) were simply complexed through electrostatic interactions to form PECs and then centrifuged to allow a hydrogel-like material. Bioelectronic attractiveness was demonstrated from the study, where the PE gel could infiltrate the porous structure of carbon electrodes to enhance the charge transfer at the electrolyte and electrode interphase whilst retaining the polymeric network structure [ 199 ]. In an analogous study, PE gels with added glycerol were prepared by radical polymerisation.…”

Polyelectrolyte gels are an important class of polymer gels and a versatile platform with charged polymer networks with ionisable groups. They have drawn significant recent attention as a class of smart material and have demonstrated potential for a variety of applications. This review begins with the fundamentals of polyelectrolyte gels, which encompass various classifications (i.e., origin, charge, shape) and crucial aspects (ionic conductivity and stimuli responsiveness). It further centralises recent developments of polyelectrolyte gels, emphasising their synthesis, structure–property relationships and responsive properties. Sequentially, this review demonstrates how polyelectrolyte gels’ flourishing properties create attractiveness to a range of applications including tissue engineering, drug delivery, actuators and bioelectronics. Finally, the review outlines the indisputable appeal, further improvements and emerging trends in polyelectrolyte gels.

“…The electrochemical cell possessed a low resistance (12 Ohm cm −2 ) while utilizing porous graphene as electrode material and an areal‐ capacitance values up to 2.74 mF cm −2 (3.1 F g −1 ) because of the efficient penetration of the PGE inside the porous electrode materials thereby enhancing the charge transfer occurring at the interface between the carbonaceous electrode material and the biopolymer. This reported strategy of preparing the flexible biopolymer hydrogel electrolyte is a potentially scalable process as it is void of an extra crosslinking step for the hydrogel formation that might prove to be critical in opening up new path in the emerging sector of next‐gen biocompatible, bioelectronics [41] …”

With a huge upsurge in the energy requirements all over the world, development of energy storage devices with high safety standards without compromising the ecological aspects has become the need of the hour, that propelled the scientific community to search for alternative yet promising sources of energy that would prevent the exhaustion of natural resources. Numerous attempts have been undertaken to utilize the renewable biopolymers in the evolution of solid‐ state electrolytes, as a substitute for liquid electrolytes which are prone to cause leakage leading to hazardous accidents. Despite strenuous efforts, it is still challenging to strike a right balance between the biopolymer elements and the conducting additives. In this review, we aim to lay out a recap on the progress achieved in recent times by employing biopolymers as electrolyte components and its future prospects, that would assist the researchers across the globe to inch one step closer in their quest to find the best electrolyte system for flexible electronics.

“…3.8 ± 0. The hydrogel of GE (30GE) exhibits a slight positive potential (see Table 3), which is due to the positive charges of the amino acids present in the chemical backbone of the gelatin [16 becomes negative when CS is incorporated into the bionanocomposite hydrogel (see Table 3) with increasing values as the CS concentration augments attaining values above the stability network threshold (±20-30 mV) [18,45].…”

Creating flexible, high-strength hydrogels from harmless, low-cost natural polymers is an area of intense research today due to their potential applications in the biomedical field, which demands materials with ambivalent physicochemical features. In particular, great efforts were devoted to the preparation of sustainable biohydrogels, composed of hydrophilic networks of renewable, biocompatible, biodegradable and low-cost biopolymers. Bionanocomposites are a promising synthetic approach to combine specific multifunctional materials with targeted physicochemical properties. Novel bionanocomposite hydrogels were designed by combining both chondroitin sulfate (CS) as well as gelatin (GE) obtained from the waste generated by the fish industries to form double fibre networks with tailored properties. In addition, hybrid bionanocomposites were achieved by introducing graphene nanoparticles (xGnP) into the double fibrillar network (GE/CS) to enhance the physicochemical properties. The bionanocomposite nanostructures were characterized by Fourier transform infrared spectroscopy (FTIR), differential scanning calorimeter (DSC) whilst their rheological properties and thermal stability were determined by rheological and thermogravimetric analyses (TGA), respectively.The likely interactions between CS and gelatin in the GE/CS hydrogel network were proved by ATR-FTIR spectroscopy. The incorporation of xGnP improved the mechanical properties of the GE/CS fibrillary network by an order of magnitude in the shear storage modulus.Eventually, the generated bionanocomposites hydrogels and bionanocomposite hybrid hydrogels have promising potential for applications in many biomedical fields, including drug delivery and tissue engineering by mimicking tissue extracellular matrix components such as the gelatin for collagen and the CS in the cartilage.
