Robust organohydrogel with flexibility and conductivity across the freezing and boiling temperatures of water

A tough double-network (DN) organohydrogel, obtained by simply soaking a poly(2-acrylamido-2-methylpropane sulfonic acid)/polyacrylamide (PAMPS/PAAm) hydrogel in an ethylene glycol solution of lithium chloride, retains high mechanical performance, flexibility (-80 to 120 degrees C) and conductivity (-20 to 120 degrees C), paving the way towards broad applications.
