- Abstract
Conductive hydrogels have attracted widespread attention in diverse applications. However, the fragile nature of conducting polymers hinders the long‐time stability of the hydrogels. What's more, hydrogels will lose elasticity and conductivity at room temperature or sub‐zero temperature because of the high water content. Herein, we proposed a long‐term stable and anti‐freezing organohydrogel with high stretchability (up to 1140%), which consist of multi‐functional nano‐micelles (Pluronic F127 diacrylate [F127DA]), Polyacrylamide, and Poly(3,4‐ethylenedioxythiophene): polystryrene sulfonate (PEDOT:PSS) in a water/glycerin binary solvent system. The gel is thermal tolerant to maintain all the properties under extreme wide temperature spectrum (−40°C or 60°C). More importantly, the organohydrogel possesses excellent recognition capability to multiple stimuli. It is anticipated that this organohydrogel will have great potential in sensing applications.
