“…Efforts have been made towards functional hydrogels in order to extend their mechanical strength and self‐repair properties via the addition of fillers or adhesives . The self‐healing hydrogels follow various types of mechanisms, such as hydrogen bonding, ionic interactions, host–guest interactions, crystallization, π – π interactions and multiple intermolecular interactions, which are involved in crack repair and re‐formation of their network structures …”

“…Hence, due to the merits of non‐toxicity, water solubility, low‐cost, and environmental friendliness, CMC has been widely used for producing hydrogels, and has been developed in many fields, including tissue engineering, drug delivery, and wound dressing . Some bifunctional molecules are employed as the crosslinker for cellulose and its derivatives to covalently bind the polymer molecules in a three‐dimensional (3D) hydrophilic network for producing hydrogels.…”

Skin loss can be caused by accident, burn, trauma, chronic wounds, and diseases, which is severely aggravated by multidrug‐resistant bacterial infections. Soft hybrids based on biopolymers combined with silver nanoparticles (AgNPs) have potential applications as wound dressing supports and skin tissue repair. Thus, our study focused on the design, green synthesis, and comprehensive characterization of carboxymethyl cellulose (CMC–AgNP) nanocomposites for producing hydrogel membranes, with tunable physicochemical properties, cytocompatibility, and biocidal activity for potential application as wound dressing and skin repair. These nanocomposites were prepared using CMC with two degrees of carboxymethylation, distinct concentrations of citric acid (CA) crosslinker, and AgNPs by in situ chemical reduction, forming hybrid membranes by the solvent casting method. The results demonstrated that superabsorbent hydrogels were produced with swelling and degradation behaviors dependent on the concentration of CA crosslinker, degree of carboxymethylation of CMC, and content of AgNP in the matrices. Moreover, the Fourier transform infrared spectroscopy analysis evidenced that the CMC functional groups (e.g., COOH and OH) were directly involved in the chemical reactions for the formation of AgNPs and hydrogel crosslinking pathway. These nanocomposites were cytocompatible using in vitro 3‐(4,5‐dimethyl‐2‐thiazolyl)‐2,5‐diphenyltetrazolium bromide cell viability assay with of human embryonic kidney cells. Conclusively, the CMC–AgNP nanohybrids demonstrated to be simultaneously non‐toxic combined with highly effective antibacterial activity against gram‐positive multi‐resistant wound/skin pathogens (Staphylococcus aureus) and moderate effect towards gram‐negative strains (Escherichia coli and Pseudomonas aeruginosa). © 2017 Wiley Periodicals, Inc.

“…The uncoupling and recoupling of their linkages occur dynamically in the hydrogel network, possibly leading to its self‐healing capability. Self‐healing mechanism of physical self‐healable hydrogels rely on intermolecular forces such as electrostatic interaction, hydrophobic association, and hydrogen bond, which reconstruct the hydrogel network after its damage. Although hydrogen bond is considered to be a weak intermolecular/intramolecular force, mechanical strength of H‐bonding hydrogels can be outstanding.…”

“…Dai et al discovered that poly ( N ‐acryloyl glycinamide) could form supramolecular hydrogel with 1.1 MPa tensile strength due to H bonding. Zheng et al fabricated a kind of H bonding carboxymethyl cellulose hydrogel with 2.5 MPa compressive strength and 80% of self‐healing efficiency…”

Deferoxamine grafted alginate (SA‐DFA) was successfully synthesized via amidation of sodium alginate with deferoxamine mesylate as determined by H‐NMR and elemental analysis. SA‐DFA with different graft yield was obtained by adjusting the ratio of sodium alginate and deferoxamine mesylate. It was found that aqueous solution of SA‐DFA could form hydrogel spontaneously due to hydrogen bonding interactions, which also endowed the SA‐DFA hydrogel with self‐healing capability. The healing efficiency of SA‐DFA hydrogels ranged from 53.64 to 90.16%. In addition, surface morphologies of SA‐DFA hydrogels before/after self‐healing process were demonstrated by SEM images. We anticipated that such self‐healable alginate hydrogel would be applied in the field of wound healing. © 2017 Wiley Periodicals, Inc. J. Polym. Sci., Part B: Polym. Phys. 2017, 55, 856–865
