“…Over the past 10 years, various types of self‐healing hydrogels have emerged, including double‐network (DN) hydrogel, nanocomposite, ion crosslinking, etc. The main feature of self‐healing hydrogels is to introduce reversible physical crosslinking as the bonds to sacrifice in the covalent network.…”

In this work, poly(acrylic) acid-chitosan @ tannic acid-aluminum ion (PAA-CS@TA-Al 3+ ) double-network hydrogel was prepared via prefabrication, blending method, and Al 3+ immersion method. The interaction between chitosan and tannic acid (CS@TA) was analyzed using Fourier transfer infrared spectra and UV-Vis spectra. The UV-Vis spectrum was also used to confirm the formation of ionic coordination in the gel. Then, the possible coordination modes were studied and analyzed. The microscopic pore structure and macroscopic strain behavior of the gel were analyzed using SEM and tensile testing, respectively, which verified that the tensile strength (≈32 KPa) and elongation at break (≈1700%) of the gel primarily resulted from its crosslinking structure. In addition, the gel also demonstrated a good self-healing performance with recovery ≈92.2% at 60 minutes.Hence, the proposed novel self-healing gel can provide inspiration for the preparation of future self-healing gels.

“…Similar to other self-healing polymers, the self-healing hydrogels were developed based on two strategies-intrinsic and extrinsic, where the former has garnered more attention. The extrinsic strategy is applied by incorporation of the modified nanoparticles (Rao et al, 2019) and nanocellulose (Bai et al, 2019) or via the release of healing agents from ruptured micro/nanoscale capsules and fibers (Fang et al, 2013). The intrinsic self-healing ability of hydrogels is mostly induced through the physical non-covalent interactions and reversible chemical covalent bonds.…”

Since the introduction of tissue engineering as an encouraging method for the repair and regeneration of injured tissue, there have been many attempts by researchers to construct bio-mimetic scaffolds which mimic the native extracellular matrix, with the aim of promoting cell growth, cell proliferation, and restoration of the tissue's native functionality. Among the different materials and methods of scaffold fabrication, one particularly promising class of materials, hydrogels, has been extensively studied, with the inclusion of nano-scaled materials into hydrogels leading to the creation of an exciting new generation of nanocomposites, known as nanocomposite hydrogels. To closely mimic the native tissue behavior, scientists have recently focused on the functionalization of incorporated nanomaterials via chiral biomolecules, with reported results showing great potential. The current article aims to introduce a perspective of nano-scaled cellulose as a promising nanomaterial which can be multi-functionalized for the fabrication of nanocomposite hydrogels with applications in tissue engineering and drug delivery systems. This article also briefly reviews the recently reported literature on nanocomposite hydrogels incorporated with chiral functionalized nanomaterials. Such knowledge paves the path for the development of tailored hydrogels toward practical applications.

Background: Hydrogels, a type of three-dimensional (3-D) crosslinked network of polymers containing a high water concentration, have been receiving increasing attention in recent years. Self-healing hydrogels, which can return to their original structure and function after physical damage, are especially attractive. Some selfhealable hydrogels have several kinds of properties such as injectability, adhesiveness, and conductivity, which enable them to be used in the manufacturing of drug/cell delivery vehicles, glues, electronic devices, and so on. Main Body: This review will focus on the synthesis and applications of self-healing hydrogels. Their repair mechanisms and potential applications in pharmaceutical, biomedical, and other areas will be introduced. Conclusion: Self-healing hydrogels are used in various fields because of their ability to recover. The prospect of self-healing hydrogels is promising, and they may be further developed for various applications.
