The mechanism of PI conversion to LIG can be studied via the ReaxFF molecular dynamics methodology . In this approach, all effects of the laser treatment are modeled via increased temperature (lasing power) and the dynamics are propagated for several nanoseconds. As a result, doped defected and twisted graphene layers are obtained, and various gases are liberated during this process. In the vacuum, the graphene sheet is typically terminated by H atoms, or the valences are unsaturated. When oxygen is present in the simulation box, the LIG yield is ca. 40% smaller and the product is oxygen-terminated, which is most presumably the cause of the amorphous graphene produced at higher laser powers. Fig. shows CV studies of the discussed LIG electrodes, tested with a [Fe(CN)6] 3-/4-redox probe, proving that current density and thereby the electrochemical activity of LIGs depends on laser parameters. Current density is the kinetic parameter describing the reaction rate. As the current density was only normalized by geometric surface area A, this parameter is primarily affected by the heterogeneous rate constant k and/or EASA, when using different LIG fabrication protocols. The first parameter is largely dependent on electrode chemistry and structure, while the latter may be enhanced by electrode geometry, both being subject to change for different lasing protocols. It is interesting to note, that P12% LIG is characterized by a more than two times higher peak current density compared to the P13% sample, which points out how much LIG laser power affects the charge transfer process. Yet, considering the XPS and Raman spectroscopy results, it appears that graphitic content is not the only factor determining electrochemical behavior. CV analyses were performed in a wide range of operating parameters: lasing power and laser speed, summarized in SI file, Fig. . These results reveal that 12% laser power and 160 mm/s laser speed appear to be the optimal conditions in our case, with the highest J and the lowest ΔE among the studied electrodes. The repeatability of LIG fabrication, in terms of CVs kinetics, was illustrated in SI file, Fig. .
