“…[64] Tannic acid (TA) is a kind of plant-derived natural polyphenols with strong antioxidant, antibacterial, and antiinflammatory properties. [176] Due to the presence of phenolic hydrogel groups, tannic acid can form hydrogel networks with hydrophilic macromolecules (such as PEG, [177] PVA, [178] PHEAA, [179] etc.) though multiple hydrophobic and hydrogen bond interactions.…”

Hydrogels, as the most typical elastomer materials with three-dimensional (3D) network structures, have attracted wide attention owing to their outstanding features in fields of sensitive stimulus response, low surface friction coefficient, good flexibility, and bio-compatibility. Because of numerous fresh polymer materials (or polymerization monomers), hydrogels with various structure diversities and excellent properties are emerging, and the development of hydrogels is very vigorous over the past decade. This review focuses on state-of-the-art advances, systematically reviews the recent progress on construction of novel hydrogels utilized several kinds of typical polymerization monomers, and explores the main chemical and physical cross-linking methods to develop the diversity of hydrogels. Following the aspects mentioned above, the classification and emerging applications of hydrogels, such as pH response, ionic response, electrical response, thermal response, biomolecular response, and gas response, are extensively summarized. Finally, this review is done with the promises and challenges for the future evolution of hydrogels and their biological applications.

“…Indeed, the wet-contact adhesive strengths of the PVA/PTPM NH coatings on both silicate glass and PMMA were much higher than many commercial glues and high-performance polymeric adhesives in literatures (Figure 2h). [39,44,[49][50][51][52][53][54][55][56][57] Even for two surfaces of dissimilar materials, this PVA/PTPM NH could still glue them. For examples, the wet-contact adhesive strengths between glass slides to steel, aluminum and PMMA slides were found to be ≈1091 ± 159, ≈1082 ± 128, and ≈839 ± 83 KPa, respectively (Figure S18, Supporting Information).…”

Fogging on optical devices may severely impair vision, resulting in unacceptable adverse consequences. Hydrophilic coatings can prevent surface fogging by instantly facilitating pseudo-film water condensation but suffer from short antifogging duration due to water film thickening with further condensation. Here, an innovative strategy is reported to achieve longer antifogging duration via thickening the robust bonded hydrophilic/hydrophobic polymer heteronetwork coating to enhance its water absorption capacity. The combination of strong interfacial adhesion and hydrophilic/hydrophobic heteronetwork structure is key to this approach, which avoids interfacial failure and swelling-induced wrinkles under typical fogging conditions. The developed antifogging coating exhibits prolonged antifogging durations over a wide temperature range for repetitious usages. Eyeglasses coated with this coating successfully maintained fog-free vision in two typical scenarios. Besides, the coating recipes developed in this study also have potential as underwater glues as they demonstrate strong adhesions to both glass and polymer substrates in wet conditions.

“…The variations of mechanical performances are related to the density and strength of physical crosslinks in the composite hydrogels, in which strong and dense hydrogen bonds should be formed between the amino groups of PHU and the acrylic acid groups of P(SA-co-AAc), besides the hydrophobic associations between SA units. [51][52][53][54] To verify the existence of hydrogen bonds in PHU/P (SA-co-AAc) composite hydrogels, Fourier transform infrared (FTIR) spectroscopy is conducted, and the spectra of PHU, P(SA-co-AAc), and PHU/P(SA-co-AAc) composite films are compared in Figure 4. In the spectra of PHU and P(SA-co-AAc), the peak at 1251 cm À1 is assigned to the bending vibrations of carbonyl group.…”

Fluorescent hydrogels have promising applications in biomedical and engineering fields. However, they are usually mechanically weak. Here, we report a fluorescent composite hydrogel with high toughness, which is facilely prepared by solution casting ethanol solution of poly(hydroxyurethane) (PHU) and poly(stearyl acrylate‐co‐acrylic acid) (P[SA‐co‐AAc]) followed by swelling the casted film in water. The composite hydrogels with water content of 62–78 wt% possess remarkable mechanical performances, with tensile breaking stress of 0.3–1.1 MPa, breaking strain of 280%–400%, Young's modulus of 0.2–0.7 MPa, and tearing fracture energy of 1250–2630 J/m2. The high toughness is attributed to the effective energy dissipation of the network with hydrophobic association of SA units and hydrogen bonds between PHU and P(SA‐co‐AAc) as the physical crosslinks. The intense aggregation of carbamates and the formation of carbamate clusters through intra‐ and intermolecular hydrogen bonds endow the composite hydrogel with strong fluorescence. These hydrogels with high toughness and strong fluorescence should find applications in flexible electronics, information display, and biomedical devices.
