As lasing power increases, the total production yield of LIG plummets, because of higher mass loss from the system. Under these conditions, smaller LIG clusters are formed. The burst and violent release of hot gases can probably detach and carry small LIG-like residues from underlying structures. However, the speed and temperature of gaseous by-products drop significantly at the exit point, resulting in the precipitation of these materials on the LIG surface, which is probably the source of the fractal-like structures observed in Fig. . At an even higher laser power, the spread of graphene-like debris around the LIG electrodes, was observable under an optical microscope. In addition, results from ReaxFF simulations indicate that the release of by-product gases will result in high porosity structures, as observable in Contact angle measurements, allowing the assessment of LIGs hydrophilicity, are given in Fig. and, for P12% and P13% samples, respectively. The resulting values of the water contact angles indicate their hydrophobic nature, with CA exceeding 120 regardless of lasing parameters, which corresponds to a low share of polar moieties by XPS analysis, only slightly higher for the P13% sample. LIG porous (at lower length scales) and grooved (at higher length scales) geometry, as determined by SEM results, may further contribute to hydrophobicity, through the Cassie-Baxter state . The low wettability offered by as-fabricated LIGs may result in sub-optimal electrochemical behavior, without post-processing surface engineering, diminishing effective EASA values.
