“…This is because glass has weaker interfacial interactions with catechol and lower surface roughness than other substrates (iron, aluminum, wood). [82,83] The effect of Fe 3+ on bonding strength was also investigated. To obtain the optimal ratio of Fe 3+ to the prepared cellulose-based bioadhesive polymer, the bonding strengths of adhesives with different addition of Fe 3+ were measured, as shown in Figure S3, Supporting Information.…”

Numerous traditional adhesives have good adhesion in dry environments. However, non-environmental-friendliness and poor water resistance largely limit their practical applications. To prepare biocompatible adhesives with strong water resistance and adhesion strength, in this paper, catechol-functionalized cellulose-based adhesive polymers are synthesized by grafting N-(3,4-dihydroxyphenethyl)methacrylamide and methyl methacrylate onto cellulose chain through atom transfer radical polymerization (ATRP). The successful synthesis of the catechol-functionalized cellulose-based adhesive polymers is confirmed by FTIR and 1 H NMR. The different characteristics of the adhesive polymers, such as thermal stability, swelling ratio, biocompatibility, and adhesion strength are investigated. Strong water resistance on various substrates is realized in underwater environment for the catechol-functionalized cellulose-based adhesive with addition of Fe 3+ . The adhesion strength and thermal stability are enhanced when the catechol content is increased. The adhesive with catechol content of 25.4% shows the adhesion strength of 0.45 MPa for iron substrate in underwater environment. In addition, the adhesive with addition of Fe 3+ exhibits excellent adhesion in dry environment, with maximum adhesion strength of 3.50 MPa for iron substrate. The cell culture test shows that the adhesive polymers have excellent biocompatibility. The biocompatible adhesives with strong water resistance have potential application in electronic, wood, and building fields.

“…The spectra of the POBD hydrogel indicated that the characteristic peaks shifted from 30-45 cm −1 to a higher wave number (Figure 2a,b) owing to hydrogen bond interactions in the hydrogels. [32,33] Therefore, the new characteristic peak at 1710 cm −1 (original peak: 1690-1640 cm −1 , C═N) was ascribed to the C═N stretching vibrations in the Schiff base bonds. [26] The peak at 1376 cm −1 was ascribed to B-O, which indicates the generation of benzeneboronic ester bonds in the hydrogel.…”

Shearing-thinning injectable hydrogels, with a fixed 3D network structure, have significant potential for application in soft and hard tissue defect repair, drug delivery, wound dressings, etc. However, these hydrogels often exhibit poor in situ reforming ability in wet and underwater environments. In this study, a hydrogel with ultrafast in situ reforming ability in wet and underwater environments is prepared using modified sodium alginate-polyvinyl alcohol-dopamine. This hydrogel, with a double dynamic chemical crosslinking network, exhibits good in situ and ex situ self-healing abilities owing to the wet adhesion property of dopamine and the underwater rebuilding property of borate ester bonds. The strength of in situ self-healing is restored to 90.1% and 110.2% of the original strength and that of ex situ self-healing is restored to 101.3% and 123.9% of the original strength after 6 min of healing in water and phosphate buffer solution environments, respectively. The in situ reforming efficiency of the hydrogel is reported to be 86.6% within 5 min of being injected into the liquid environment owing to the contribution of in situ self-healing and ex situ self-healing. In addition, the proposed hydrogel has good cell compatibility. Therefore, it can be widely used as a biomaterial.

In recent years, due to their good physical and chemical properties, nanocomposite hydrogels have shown great application potential in the fields of biomedicine, sensors, 3D printing, and water pollution control. Compared with pure polymer hydrogels, the superior performance of nanocomposite hydrogels is mainly due to the influence of nanomaterials on the internal structure and composition of the hydrogels. In this paper, starting from the basic properties required for practical applications of hydrogels, the influence of nanomaterials on the different properties of hydrogels is discussed. Meanwhile, this paper reviews the research status of nanocomposite hydrogels in different application fields, and emphasizes the challenges and development prospects of nanocomposite hydrogel applications.
