Three-dimensional (3D) printing technology presents a higher flexible technique to produce different
complex geometric shapes compared to conventional manufacturing. This technology is known as
additive manufacturing (AM) may be also suitable for industrial production. AM method is widely used
in different areas, including construction, medicine, energy, and electrochemistry, recently. Polymeric
materials such as polylactic acid (PLA) and acrylonitrile butadiene styrene (ABS) filaments are used in
the 3D printing process. In this study, the conductive polymeric anode electrodes are prepared using
3D printing method. Then, these electrodes are coated with Pt in different thicknesses (0.5, 1, 1.5, and
2μm) by the electron beam evaporation (EBM) method. A thin Cr adhesion layer (20nm) is used to
improve the adhesion of the Pt coating on the sample surface. After the completion of the coating
process, the polymeric electrodes are named as Pt-0.5, Pt-1, Pt-1.5, and Pt-2. Pt coated 3D printed
polymeric electrodes have been physically characterized by using Field Emission Scanning Electron
Microscopy (FE-SEM), FE-SEM/Energy Dispersive X-Ray Spectroscopy (FE-SEM/EDX), FE-SEM
mapping, and X-Ray Powder Diffraction techniques. Cycling Voltammetry, Linear Sweep Voltammetry,
Electrochemical Impedance Spectroscopy, and Chronoamperometry analysis of the Pt coated
electrodes have been conducted to evaluate their electrochemical performance.
