Raman spectroscopy analysis of poly(lactic acid)-carbon black composite treated by femtosecond laser

The dataset contains the Raman spectroscopy measurements of commercially available carbon black-filled poly(lactic acid) 3D printed electrodes after femtosecond laser ablation. These results were utilized in the manuscript published in Electrochimica Acta: 10.1016/j.electacta.2022.140288
The FSL 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. A Raman analysis was performed using a Raman microscope (InVia, Renishaw, UK). Spectra were recorded in the range of 150–3200 cm−1 using an argon-ion laser emitting at 514.5 nm and operating at 1% of its total power (50 mW) to avoid melting the PLA.
