Polypyrrole (PPy) has been used widely as pseudocapacitive materials due to the unique combination of properties such as readily available, easy synthesis, relatively high capacitance, and intrinsic flexibility property. However, the PPy as an electrode material has poor cycling stability and mechanical integrity resulting from the swelling and shrinking during charging and discharging cycles. To this end, crosslinking the PPy chains can be a solution for overcoming these drawbacks. Moreover, making the hybrid structure with which can further boost the physical and electrochemical properties of the PPy network would be further advantageous. Herein, we report the phytic acid (PA) mediated self-assembled polypyrrole networks by one-pot fabrication step for energy storage application. Simultaneous interaction of PPy segments with PA via hydrogen bonding and electrostatic interaction results in the formation of hierarchical porous crosslinked PPy networks as the electrode material. |
