Abstract The hydrogels with self-healing properties have high potential applications in the biomedical field. Generally, the imine bonds are used as the dynamic covalent bonding in the self-healing hydrogels and hydrogen bonding is used for providing additional strength to self-healing hydrogels. In the presented work, Gelatin, dialdehyde dextrin, and dialdehyde Carboxymethyl cellulose (CMC) based hydrogels were prepared which are biocompatible and biodegradable and hence, can be used in biomedical field. Borax and glutaraldehyde were used as binding agent and cross-linker, respectively. The dynamic imide bond formed between gelatin-dialdehyde dextrin, gelatin-dialdehyde CMC, and gelatin-glutaraldehyde were responsible for self-healing ability of the prepared hydrogel. The rheological studies were also carried out which showed that as a consequence of lower viscosity the hydrogels can show injectable properties. The sample was also found to be blood compatible, which further highlights its biomedical importance.

Currently, self-healing hydrogels prepared from the green process have been studied for various applications, especially in the biomedical field. This work fabricated the self-healing hydrogel based on sodium carboxymethyl cellulose/poly(vinyl alcohol)/montmorillonite by acidifying the mixture with citric acid. SEM measurements showed well-dispersed montmorillonite in the hydrogels. Cytotoxicity values >100% were seen with montmorillonite added, which indicated cell growth and no cell toxicity. Montmorillonite addition not only reinforced the networks but also improved self-healing ability. The tensile strength of the original uncut hydrogel with montmorillonite (P1C8M1) was 61 kPa, whereas the healed hydrogel showed 57 kPa. The hydrogel healed completely within 10 days, without any cracks, i.e., a 93% healing efficiency, or higher than the ~60% of the non-reinforced hydrogel. This confirmed strong hydrogen bond formation between the polymer and montmorillonite. The self-healing ability of this non-toxic hydrogel, reinforced with montmorillonite, makes it valuable for use in biomedical fields.
