Images revealing the effect of local femtosecond laser ablation of conductive poly(lactic acid) 3D printed electrodes

Description

The dataset reveals the images of the femtosecond laser (FSL) ablation at the surface of commercially available carbon black-filled poly(lactic acid) 3D printed electrode. The process is used for the increase of the charge transfer of this electrode in electrochemical studies.

The FSL delivered a Gaussian beam with pulse energy between 4 µJ and 44.4 µJ depending on the pulse repetition rate adjustable from 1 MHz to 50 kHz, respectively. In the case of the current research, the pulse frequency was set to 200 kHz corresponding to a maximal pulse energy of 20.1 µJ. The laser beam was focused on the sample surface to a spot of 25 µm diameter and the sample surface was scanned by means of an XY galvanometer scanner. Different values of energy density on the sample surface, as a percentage value of the maximal pulse energy.

The dataset contains scanning electron microscopy images of samples ablated at various laser power. Different energy densities used are labeled as percentages in micrograph file names. Supporting optical microscopy images (at various magnifications) are also included.

The selected micrographs were utilized when preparing the manuscript published in Electrochimica Acta: 10.1016/j.electacta.2022.140288
