“…Hence, hydrogels with high mechanical strength and high adhesion are the focus of some researchers. Guo [ 27 ] used Bovine Serum Albumin (BSA) and polyacrylamide to prepare DN hydrogel. Through physical interaction and chemical covalent cross-linking, such as hydrogen bond and chain entanglement, the hydrogel has good mechanical properties and adhesion.…”

Hydrogels with a three-dimensional network structure are particularly outstanding in water absorption and water retention because water exists stably in the interior, making the gel appear elastic and solid. Although traditional hydrogels have good water absorption and high water content, they have poor mechanical properties and are not strong enough to be applied in some scenarios today. The proposal of double-network hydrogels has dramatically improved the toughness and mechanical strength of hydrogels that can adapt to different environments. Based on ensuring the properties of hydrogels, they themselves will not be damaged by excessive pressure and tension. This review introduces preparation methods for double-network hydrogels and ways to improve the mechanical properties of three typical gels. In addition to improving the mechanical properties, the biocompatibility and swelling properties of hydrogels enable them to be applied in the fields of biomedicine, intelligent sensors, and ion adsorption.

“…Besides, the adhesive strength for the optimum hydrogel on other daily substrates can also compete with existing literatures. [ 36–40 ] Additionally, the optimal DMAPMA‐C18/DMAc/CNC‐G hydrogel could also adhere firmly on the fresh chicken breast specimens under water as demonstrated in Figure S5 (Supporting Information) further emphasizing the universal adhesion ability of the hydrogel to challenging surfaces including wet tissue surface.…”

Highly stretchable, repairable, and tough nanocomposite hydrogels are designed by incorporating hydrophobic carbon chains to create first‐layer cross‐linking among the polymer matrix and monomer‐modified polymerizable yet hydrophobic nanofillers to create second‐layer strong polymer‐nanofiller clusters involving mostly covalent bonds and electrostatic interactions. The hydrogels are synthesized from three main components: hydrophobic monomer DMAPMA‐C18 by reacting N‐[3‐(dimethylamino)propyl]methacrylamide] (DMAPMA) with 1‐bromooctadecane, monomer N,N‐dimethylacrylamide (DMAc), and monomer‐modified polymerizable hydrophobized cellulose nanocrystal(CNC‐G) obtained by reacting CNC with 3‐trimethoxysily propyl methacrylate. The polymerization of DMAPMA‐C18 and DMAc and physical cross‐linking due to the hydrophobic interactions between C18 chains make DMAPMA‐C18/DMAc hydrogel. The additional introduction of CNC‐G brings more interactions into the final hydrogel (DMAPMA‐C18/DMAc/CNC‐G): the covalent bonds between CNC‐G and DMAPMA‐C18/DMAc, hydrophobic interactions, electrostatic interactions between negatively charged CNC‐G and positively charged DMAPMA‐C18, and hydrogen bonds. The optimum DMAPMA‐C18/DMAc/CNC‐G hydrogel exhibits excellent mechanical performance with elongation stress of 1085 ± 14 kPa, strain of 4106 ± 311%, toughness of 3.35 × 104 kJ m−3, Young's modulus of 844 kPa, and compression stress of 5.18 MPa at 85% strain. Besides, the hydrogel exhibits good repairability and promising adhesive ability (83–260 kN m−2 toward various surfaces).

“…The maximum shear stress was obtained at the breaking point, and the shear toughness was the enclosed area by the shear stress and displacement. The shear stress and the shear toughness of the P(VSA‐co‐DMAPAA) fiber to the printing paper were 9.17 MPa and 63.22 MJ m −3 (Figure 3e,f), respectively, which is among the best of the reported sticky hydrogel materials, such as poly(Thioctic acid‐diisopropenylbenzene‐Fe 3+ ) (poly(TA‐DIB‐Fe), 0.38 MPa) , [ 32 ] Polyzwitterion‐clay (SBMA‐clay) hydrogel (0.041 MPa) , [ 36 ] skin temperature‐triggered smart milk‐derived hydrogel (STSMH hydrogel, 0.025 MPa) [ 45 ] and bovine serum albumin‐polyacrylamide (BSA‐PAM) hydrogel (0.25 MPa) [ 46 ] (Figure 3i).…”

Neuron‐Inspired Sticky Artificial Spider Silk for Signal Transmission

Neurons exhibit excellent signal transmission capacity, which inspire artificial neuron materials for applications in the field of wearable electronics and soft robotics. In addition, the neuron fibers exhibit good mechanical robustness by sticking to the organs, which currently has rarely been studied. Here, a sticky artificial spider silk is developed by employing a proton donor‐acceptor (PrDA) hydrogel fiber for application as artificial neuron fibers. Tuning the molecular electrostatic interactions by modulating the sequences of proton donors and acceptors, enables combination of excellent mechanical properties, stickiness, and ion conductivity. In addition, the PrDA hydrogel exhibits high spinning capacity for a wide range of donor‐acceptor combinations. The PrDA artificial spider silk would shed light on the design of new generation of artificial neuron materials, bio‐electrodes, and artificial synapses.
