Abstract

Ionogels are a class of soft materials composed of ionic liquids and polymer networks. They possess many fascinating intrinsic properties (

e.g.

ionic conductivity

near-zero vapor pressure

and wide thermal and electrochemical operation windows) that make them promising for applications in ionotronics

sensors

energy storage devices

and flexible electronics. In addition to these intrinsic properties

ionogels can acquire additional functionalities (such as self-healing

shape memory

and adhesion) through structural design and the introduction of functional additives

thereby further expanding their application scope. This review focuses specifically on these additional functionalities of ionogels

elucidating their design strategies and applications and highlighting the current challenges and future opportunities in this rapidly developing field.
