the present work, a new strategy is proposed to simultaneously enhance
the toughness and electrochemical performance of the hydrogel with
conductive microgel to form microgel-reinforced double network hydrogel.
In this hydrogel, the conductive microgel is cross-linked to form
the first network, which can dissipate energy to improve mechanical
performance and stabilize the conductive network to improve the electrochemical
performance. These hydrogels show excellent mechanical properties
and good conductivity. When these hydrogels are assembled to all-gel-state
intrinsically flexible and stretchable supercapacitor, they deliver
outstanding capacitance. The strategy put forward here can extend
the application scope of the hydrogel with multifunction.
