“…In these years, an ionic liquid formed by organic cations and inorganic anions has attracted the considerable attention of researchers, because they possess good mobility but hardly evaporate as well as display excellent conductivity. [ 63,64 ] An ionogel can be obtained by displacing the whole water of hydrogel using ionic liquids. [ 43 ] Scrupulously speaking, the ionogel cannot be called a hydrogel.…”

Hydrogels have been widely explored to adapt to different application circumstances. As typical wet‐soft materials, the high‐water content of hydrogels is beneficial to their wide biomedical applications. Moreover, hydrogels have been displaying considerable application potential in some high‐tech areas, like brain‐computer interface, intelligent actuator, flexible sensor, etc. However, traditional hydrogel is susceptive to freezing below zero, dehydration, performance swelling‐induced deformation, and suffers from mechanical damage in extremely mechanical environments, which result in the loss of wet‐soft peculiarities (e.g., flexibility, structure integrity, transparency), greatly limiting their applications. Therefore, reducing the freezing point, improving the dehydration/solution resistance, and designing mechanical adaptability are effective strategies to endow hydrogels with the extreme environmental adaptability, thus broadening their application fields. This review systematically summarizes research advances of environmentally adaptive hydrogels (EAHs), comprising anti‐freezing, dehydration‐resistant, acid/base/swelling deformation‐resistant, and mechanical environment adaptive hydrogels (MEAHs). Firstly, fabrication methods are presented, including the deep eutectic solvent/ionic liquid substituent, the addition of salts, organogel, polymer network modification, and double network (DN) complex/nanocomposite strategy, etc. Meanwhile, the features of different approaches are overviewed. The mechanisms, properties, and applications (e.g., intelligent actuator, wound dressing, flexible sensor) of EAHs are demonstrated. Finally, the issues and future perspectives for EAHs’ researches are demonstrated.

Cation effects on the properties of halloysite-confined bis(trifluoromethylsulfonyl)imide based ionic liquids

Abstract: The structure and properties of ionic liquids based on the bis(trifluoromethylsulfonyl)imide anion confined by halloysite nanoclay change due to interaction with outer and inner surfaces of nanotubes, depending on the type and size of the cation.
