abstract = "The objective of this study was to develop optimal laser parameters (resolution, power, and velocity) for the formation of graphene on poly(dimethylsiloxane) (PDMS)-based materials using laser-induced graphene (LIG). A series of novel PDMS/poly(ethylene glycol) (PEG) materials with varying concentrations of PEG (30, 40, and 50 wt.%) was prepared through a blending approach. For comparison, pure PDMS was prepared using a casting method. To the best of our knowledge, the synthesis of PDMS/PEG materials and the direct laser graphenization (LIG) of PDMS/PEG materials have not been reported in the literature. Once the optimal laser parameters were established, the prepared PDMS/PEG/graphene composites were characterized using Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and scanning electron microscopy (SEM). The results demonstrated that the addition of PEG led to an enhanced degree of graphenization compared to the pure PDMS sample, which did not induce graphene formation. Among the materials tested, the PDMS/PEG/graphene composite with 30 wt.% PEG in the PDMS matrix exhibited the optimal degree of graphenization. SEM analysis of the LIG on PDMS/PEG material revealed a porous network structure. With their improved properties, the developed PDMS/PEG/graphene composites hold promise as materials suitable for the production of flexible electronic devices.",
