Implication

Randomized trial explores photothermal nanomaterial impacts on graphene formation in polyimide films, suggesting design guidelines for low-power fabrication.

Key Points

This study aims to quantitatively understand the effects of photothermal nanomaterials on the formation of laser-induced graphene.
Systematic investigation using a CO2 laser on polyimide films coated with various nanomaterials (SWCNTs, MWCNTs, graphene oxide, MXene).
Time-resolved infrared thermography assessed heating dynamics and laser power thresholds for LIG formation.
Cross-sectional scanning electron microscopy analyzed the morphology and characteristics of the LIG formed.
SWCNT coatings show the earliest rapid temperature rise compared to other nanomaterials.
The laser power threshold for LIG formation decreases with higher nanomaterial loading.
MWCNT-assisted LIG displays a gauge factor of 152 at 20% strain, significantly higher compared to bare PI-derived LIG.
