“…192,193 The strong hydrogen bonding between TA and PVA acted as an irreversible crosslink, and the weaker hydrogen bond between PVA chains served as a temporary crosslink, leading to the formation of a shape memory hydrogel. 194 Besides, the PVA crystallite formation as a strong crosslinker in PVA hydrogel was inhibited by the hydrogen bonding between TA and PVA. Interestingly, PVA/TA hydrogel can exhibit deformation recovery and shape memory behavior by immersing in 60 1C water due to the easy destruction and re-formation of weaker hydrogen bonds between PVA chains.…”

“…PVA can also be combined with other types of polymers to improve the superior properties of the resulting hydrogel. Guo [29] has made PVA hydrogel/tannic acid/aramid nanofiber as a wound dressing. The hydrogel showed excellent mechanical properties, broad-spectrum antibacterial properties, and low cytotoxicity thus confirming its potential application as a wound dressing.…”

Hydrogel is composed of a three-dimensional network of hydrophilic polymers and can swell when placed in an aqueous media. Polyvinyl alcohol (PVA) is a common polymer used to produce hydrogels because it has biocompatibility, non-toxicity, chemical stability, low cost, and excellent mechanical strength. In this study, the PVA solutions were prepared with concentrations of 6%, 8%, 10%, and 12% in distilled water. The precursor solutions underwent a freeze-thaw cycle with a freezing temperature of -25 °C for 20 hours and a thawing temperature of 37 °C for 4 hours and carried out for 6 cycles. The swelling degree and the gel fraction of the hydrogel were then determined. From the swelling degree results, the increase of the PVA concentration in the precursor solutions reduced the swelling degree of the hydrogel. Based on the gel fraction test, it was revealed that all PVA concentrations have approximately the same value of gel fraction at 97%. Additionally, the viscosity and the density were also measured. Both showed an increasing trend with the addition of PVA concentration, where the viscosity values from the smallest to highest concentrations were 12.4944, 34.1737, 93.8491, and 216.2979 cP while the density values were 0.9865, 0.9871, 0.9878, and 0.9885 gram.cm-3.

“…PVA-based hydrogels provide also promising platforms with a broad range of tunable mechanical properties [24,27,40,41,49,92,96,129,132,134,[142][143][144][145]. By choosing the proper method of preparation and the optimum composition, the mechanical properties of hydrogels can be modulated over a large window: tensile strength from 10 kPa to 10 MPa, toughness from 100 J/m 2 to 100 MJ/m 2 , elongation in the range 100-2100%, and elastic modulus from 1 kPa to 2.5 MPa.…”

Hydrogels, as interconnected networks (polymer mesh; physically, chemically, or dynamic crosslinked networks) incorporating a high amount of water, present structural characteristics similar to soft natural tissue. They enable the diffusion of different molecules (ions, drugs, and grow factors) and have the ability to take over the action of external factors. Their nature provides a wide variety of raw materials and inspiration for functional soft matter obtained by complex mechanisms and hierarchical self-assembly. Over the last decade, many studies focused on developing innovative and high-performance materials, with new or improved functions, by mimicking biological structures at different length scales. Hydrogels with natural or synthetic origin can be engineered as bulk materials, micro- or nanoparticles, patches, membranes, supramolecular pathways, bio-inks, etc. The specific features of hydrogels make them suitable for a wide variety of applications, including tissue engineering scaffolds (repair/regeneration), wound healing, drug delivery carriers, bio-inks, soft robotics, sensors, actuators, catalysis, food safety, and hygiene products. This review is focused on recent advances in the field of bioinspired hydrogels that can serve as platforms for life-science applications. A brief outlook on the actual trends and future directions is also presented.
