| Abstract: A two-dimensional copper tetrakis(4-carboxyphenyl) porphyrin (Cu-TCPP, H2TCPP=tetra(4-carboxyphenyl) porphyrin) nanosheet was synthesized via a one-step hydrothermal method, and a Cu-TCPP/AgNWs composite electrode was constructed through a spray coating process. The combination of Cu-TCPP and AgNWs facilitated rapid electron transfer, enhancing the electrochemical performance of flexible transparent supercapacitors (FTSCs). Experimental results showed that the Cu-TCPP/AgNWs-based FTSCs achieved a specific areal capacitance of 5.96 mF· cm-2 with a transmittance of 58.6%. Furthermore, after 180° bending and folding, the capacitance retention remained as high as 87%, demonstrating excellent mechanical flexibility. |
