Molecular dynamics simulations with generic bead–spring models have been instrumental in revealing the molecular-scale behavior that underlies structure–property relationships of various types polymeric systems. The generic, coarse-grained modeling approach does not include atomistic detail and is focused on quantitatively matching properties a particular chemical system, though typically several parameters are included can be tuned to consider different chemistries. Besides allowing access longer length time scales due computational efficiency, this type advantageous physical insight gained often relevant across entire class related materials. connectivity number beads adjusted an obvious manner describe most basic homopolymer features (e.g., chain lengths linear versus branched architectures). In uncharged copolymers or solvent-containing systems, interactions between components considered by adjusting strength pairwise interparticle potentials (usually without changing their form). However, ions stronger longer-ranged each other, solvents, monomers require additional complexity added appropriately phenomena ion-containing Recent efforts pushing boundaries including ion–ion ion–polymer more closely capture analyze such phenomena, while still avoiding detailed specific empirical adjustments would make model only apply single system. perspective, we highlight variety recent molecular work applies study We also discuss possible future directions challenges coarse-graining area.

Abstract Soft ionic conductors, such as hydrogels and ionogels, have enabled stretchable transparent ionotronics, but they suffer from key limitations inherent to the liquid components, which may leak evaporate. Here, novel liquid‐free conductive elastomers (ICE) that are copolymer networks hosting lithium cations associated anions via bonds hydrogen demonstrated, intrinsically immune leakage evaporation. The ICEs show extraordinary mechanical versatility including excellent stretchability, high strength toughness, self‐healing, quick self‐recovery, 3D‐printability. More intriguingly, can defeat conflict of versus toughness—a compromise well recognized in mechanics material science—and simultaneously overcome between conductivity properties, is common for ionogels. Several ionotronics based on ICE further developed, resistive force sensors, multifunctional skins, triboelectric nanogenerators (TENGs), not subject previous gel‐based devices, leakage, evaporation, weak hydrogel–elastomer interfaces. Also, 3D printability demonstrated by printing a series structures with fine features. findings offer promise variety requiring environmental stability durability.

Abstract Stretchable ionic conductors such as hydrogels and ionic‐liquid‐based gels (aka ionogels) have garnered great attention they enable the development of soft ionotronics. Notably, ionotronic devices inevitably operate in humid environments or under mechanical loads. However, many previously reported ionogels, however, are unstable with varying humidity levels owing to hydrophilicity, their liquid components (i.e., liquid, water) may leak easily from polymer matrices loads, causing deterioration device performance. This work presents novel hydrophobic ionogels strong retention capability. The ambiently mechanically stable, capable not absorbing moisture high relative almost losing during long periods loading.
