“…The related mechanisms can combine several dynamic chemical covalent bonds; for example, combining imine bonds with acylhydrazone bonds ( Wang L. et al, 2018 ) or with boronate-diol complexation ( Balakrishnan et al, 2019 ). On the other hand, the rest combines different physical non-covalent interactions, such as combining hydrogen bonds with ionic interaction ( Long et al, 2018 ; Jiang X. et al, 2019 ; Li S. et al, 2019 ; Lin et al, 2019 ; Song D. et al, 2019 ; Yuan et al, 2019 ; Zhang et al, 2019 ), with π-π stacking ( Liao et al, 2017 ; Gavel et al, 2018 ; Liang et al, 2019 ; Xu J. et al, 2019 ), and others ( Chen et al, 2019b ; Qiao et al, 2019 ), combining ionic interaction with hydrophobic interaction ( Chen et al, 2019b ), or combining multiple non-covalent interactions ( Wang S. et al, 2018 ; Deng et al, 2019 ). Additionally, some belong to both categories, such as using both boronate-diol complexation and hydrogen bonds ( Ding et al, 2018 ; Peng et al, 2019 ; Shao et al, 2019 ; Wang M. et al, 2019 ), both imine bond and hydrogen bonds ( Liu et al, 2018 ; Cheng et al, 2019 ), both host-guest interaction and boronate-diol complexation ( Yang et al, 2019 ), both metal-ligand coordination and hydrophobic interaction ( Tang et al, 2018 ), both dipole-dipole association and boronate-diol complexation ( Chen Y. et al, 2018 ), and multiple ones ( Jing et al, 2018 ; Qu et al, 2018 ; Pan et al, 2019 ; Xu H. et al, 2019 ).…”

Smart polymers for cell therapy and precision medicine

“…They are non-covalent interactions and dynamic covalent bonds. Non-covalent interactions include hydrogen bond [40], host-guest interactions [42], electrostatic interactions [43], π-π interactions [80], and hydrophobic interactions [44]. The weak intermolecular forces of non-covalent interactions facilitate the reversible assembly and disassembly of self-healing hydrogels.…”

Dual‐responsive shape memory hydrogels with self‐healing and dual‐responsive swelling behaviors

“…Inspired by the synergy mechanism of the DN structure, dual physically cross-linked (DPC) hydrogels were designed, prepared and also received extensive attention recently. [35][36][37][38][39][40][41] Different from PDN hydrogels, DPC hydrogels are composed of a single network formed by two totally different physical interactions. The DPC strategy could provide a convenient and effective method to design and prepare hydrogels with outstanding mechanical and shape memory performances.…”

“…Compared to traditional chemically cross‐linked DN hydrogels, 29–31 chemical–physical hybrid DN hydrogels 24,32–33 and especially fully physically cross‐linked DN (PDN) 34 hydrogels possess not only prominent mechanical properties, but also outstanding self‐healing performances arise from the reversibility of physical cross‐linkings. Inspired by the synergy mechanism of the DN structure, dual physically cross‐linked (DPC) hydrogels were designed, prepared and also received extensive attention recently 35–41 . Different from PDN hydrogels, DPC hydrogels are composed of a single network formed by two totally different physical interactions.…”
