In this work, the rGO/polyacrylic acid (rGO/PAA) composite film was synthesized using the 3D direct ink writing technique with GO/acrylic acid (GO/AA) ink and UV irradiation. Results show that after a UV irradiation time of 3.6 seconds, GO was reduced into rGO, and AA was polymerized into PAA. The prepared material was characterized by using Fourier Transform Infrared Spectroscopy (FT-IR), Energy-dispersive X-ray spectroscopy (EDX), cyclic voltammetry (CV), and galvanostatic charge/discharge technique (GCD). The obtained composite film is applied as an electrode for the supercapacitor. The electrode has a specific capacity of 321 F/g at a current density of 1 A/g and retains 82% of its initial capacity after 5,000 charge/discharge cycles at a current density of 5 A/g.
