Organosulfonate counteranions‐trapped coordination polymer as high‐output triboelectric nanogenerator material for self‐powered anticorrosion

Selection of the friction electrode materials is crucial to the performance oftriboelectric nanogenerator (TENG). In the present study, a metal-organiccoordination complex containing organosulfonate counteranions with electron-donating ability was synthesized via the coordination-driven self-assembly approach under mild reaction conditions and was chosen as positive electrode material to construct a triboelectric nanogenerator, having high-output performance with a peak value of short circuit current density of 98.6 μA and output voltage of 1180 V. As a practical application, it was shown to light up 1488 commercial green LEDs and power an anticorrosion system device to protect metals from corrosion.
