“…On the one hand, ethanol‐inducing self‐assembled polymerization of TA provides a flexible 3D organic framework that originates from the physical bonding between the medium polymer and the ILs. [ 17 ] On the other hand, AM forms spatially dispersed network clusters, effectively acting as sacrificial networks for strengthening the poly(thioctic acid‐ co ‐ acrylamide) (P(TA‐ co ‐AM)/[EE] ionogel (Figure 1d). To verify this strategy, the poly(dimethylacrylamide ‐ co ‐ acrylamide) (P(DMA‐ co ‐AM)/[EE]) ionogel was fabricated by selecting the dimethylacrylamide (DMA) as a soft physical network, and the prepared ionogel had excellent transparency (> 90%) and ultrarobust mechanical properties (tensile strength >17 MPa, toughness >40 MJ m −3 , and elongation ≈300%).…”

Ionogels are compelling materials for flexible hybrid electronics owing to their attractive physical properties and infinite adjustability of chemical structures. However, ionogels must be sufficiently strong to ensure durability, stability, and a wide range of strains in various applications to make electronic systems mechanically compliant. Inspired by the hierarchical structure of multiphase substances in the skin, it is fabricated several transparent (>90%) and ultra‐robust (tensile strength >17 MPa, toughness >40 MJ m−3, and elongation ≈300%) ionogels via in situ polymerization of polymers with the different binding abilities to the ionic liquid by forming soft and rigid confinement space. This strategy can also be applied to other ionic liquids and polymers. Furthermore, the designed ionogel sensors can be used to develop a wearable intelligent health monitoring system capable of monitoring health‐related physiological signals, such as temperature, body tremors, wrist pulse, breathing, and gestures, for predicting and responding to emergencies, which will pave the way for wearable security monitoring technology.

“…In addition to MEL-PA, other components containing flame-retardant elements have been selected for the self-assembly of 2D SFRs [ 63 , 64 , 65 , 66 ]. Most of them take advantage of multiple interactions such as electrostatic interaction, hydrogen bonding, π-π interaction, coordination between metal ions and chelating groups among different assembly units in the aqueous phase.…”

The development of different efficient flame retardants (FRs) to improve the fire safety of polymers has been a hot research topic. As the concept of green sustainability has gradually been raised to the attention of the whole world, it has even dominated the research direction of all walks of life. Therefore, there is an urgent calling to explore the green and simple preparation methods of FRs. The development of supramolecular chemistry in the field of flame retardancy is expanding gradually. It is worth noting that the synthesis of supramolecular flame retardants (SFRs) based on non-covalent bonds is in line with the current concepts of environmental protection and multi-functionality. This paper introduces the types of SFRs with different dimensions. SFRs were applied to typical polymers to improve their flame retardancy. The influence on mechanical properties and other material properties under the premise of flame retardancy was also summarized.

“…[34][35][36][37][38][39][40] With its dynamic disulde bonds, TA generates macromolecules by thermal polymerization, 41,42 photopolymerization, [43][44][45] and concentration-induced polymerization. [46][47][48] However, pol-yTA is metastable, depolymerizing into semicrystalline oligomers within a few minutes. To prevent depolymerization by ring-closure, it is necessary to quench the radical chain ends by inverse vulcanization.…”
