“…Storage modulus (G’), known as the elastic component of modulus and loss modulus (G”) or viscous constituent of modulus, were evaluated through dynamic instrumented indentation, as described previously [ 28 , 29 , 30 ] since epoxidized vegetable oil-based polymers are highly compliant materials. The obtained results (plotted in the Online Resource— Figure S4 ) show different behaviors for the tested samples.…”

Considering its great industrial potential, epoxidized linseed oil (ELO) was crosslinked with different agents, both natural and synthetic: citric acid (CA, in the presence of water—W, or tetrahydrofuran—THF, as activator molecules) and Jeffamine D230, respectively, resulting bio-based polymeric matrices, studied further, comparatively, in terms of their properties, through different methods. Thermal curing parameters were established by means of Differential Scanning Calorimetry (DSC). Fourier transform Infrared Spectroscopy (FTIR) and DSC were used to identify the reactivity of each ELO-based formulation, discussing the influence of the employed curing systems under the conversion of the epoxy rings. Then, the obtained bio-based materials were characterized by different methods, establishing the structure–properties relation. Thermogravimetric analysis revealed higher thermal stability for the ELO_CA material when THF was used as an activator. Moreover, a higher glass transition temperature (Tg) with ~12 °C was registered for this material when compared with the one that resulted through the crosslinking of ELO with D230 conventional amine. Other important features, such as crosslink density, storage modulus, mechanical features, and water affinity, were discussed. Under the loop of a comprehensive approach, a set of remarkable properties were obtained for ELO_CA_THF material when compared with the one resulting from the crosslinking of ELO with the synthetic Jeffamine.

“…[107] The combination of cross-links is known to improve the water uptake and mechanical properties (elastic recovery and tensile modulus) of polymer hydrogels at both the macro-and microscales. [108] Polyampholyte DN hydrogels can also be considered as an example of DN hydrogels with tunable structural properties. [109] The synergy of ionic and metal-ligand bonds can be used to design a wide range of polyampholyte DN hydrogels with strong and tough structures.…”

The recent and fast‐growing trends related to the development of wearable technologies have raised the need for efficient and high‐performance energy storage devices having extra features such as flexibility and lightweight. Polymer hydrogels, as viscoelastic lightweight porous nanostructures with tunable surface and structural properties, can play a crucial role in the design of these future energy storage devices. Herein, recent developments and progress in the use of polymer hydrogels to design flexible and wearable energy storage devices are presented and discussed. The 3D structure of polymer hydrogels and porous nanostructures based on these hydrogels provides a platform to design flexible supercapacitors, batteries, and personal thermal management devices. Herein, different types of polymer hydrogels are presented, and their main fabrication techniques are reported. Moreover, the main structural properties affecting the energy storage performance of polymer hydrogels are discussed. In addition to recent progress in the design of polymer‐hydrogel‐based wearable devices, recent developments in polymer hydrogels for flexible applications (batteries, supercapacitors, and thermal energy storage systems) are reviewed in detail.

“…Quality Assessment Methods for Hydrogels, Bioinks, and Bioprinted Products In the process of obtaining and developing hydrogels and bioinks and creating volumetric constructs in the TDB process, it is necessary to analyse their composition, physical and chemical properties, and the nature of the interaction between biopolymers, and assess the state and stages of development of cell components, as well as the subsequent study of stability and bioresorption of bioprinted products (bioimplants) after implantation, including their impact on the morphology and biochemistry of damaged surrounding tissue. For these purposes, a set of various physical and chemical research methods are used to assess the structure and component composition of hydrogels and bioinks, among which there is infrared spectroscopy [292][293][294], Raman spectroscopy [295], the circular dichroism method [296], the fluorescence method [297], etc. In addition, electron microscopy is used to analyse the molecular organization of networks of biopolymers that form a gel [180,296,298].…”

The musculoskeletal system, consisting of bones and cartilage of various types, muscles, ligaments, and tendons, is the basis of the human body. However, many pathological conditions caused by aging, lifestyle, disease, or trauma can damage its elements and lead to severe disfunction and significant worsening in the quality of life. Due to its structure and function, articular (hyaline) cartilage is the most susceptible to damage. Articular cartilage is a non-vascular tissue with constrained self-regeneration capabilities. Additionally, treatment methods, which have proven efficacy in stopping its degradation and promoting regeneration, still do not exist. Conservative treatment and physical therapy only relieve the symptoms associated with cartilage destruction, and traditional surgical interventions to repair defects or endoprosthetics are not without serious drawbacks. Thus, articular cartilage damage remains an urgent and actual problem requiring the development of new treatment approaches. The emergence of biofabrication technologies, including three-dimensional (3D) bioprinting, at the end of the 20th century, allowed reconstructive interventions to get a second wind. Three-dimensional bioprinting creates volume constraints that mimic the structure and function of natural tissue due to the combinations of biomaterials, living cells, and signal molecules to create. In our case—hyaline cartilage. Several approaches to articular cartilage biofabrication have been developed to date, including the promising technology of 3D bioprinting. This review represents the main achievements of such research direction and describes the technological processes and the necessary biomaterials, cell cultures, and signal molecules. Special attention is given to the basic materials for 3D bioprinting—hydrogels and bioinks, as well as the biopolymers underlying the indicated products.
