▎ 摘　　要

NOVELTY - Preparing metal and laser induced graphene (metal-LIG) nanocomposite involves exposing a polyimide-metal substrate to a blue diode laser source, where the exposing results in metal-LIG nanocomposite formation, and the graphene is derived from the polyimide, prepared from the polyimide resin without any thermal imidization. USE - Method for preparing metal and laser induced graphene nanocomposite. ADVANTAGE - The method does not use any toxic chemicals and high-temperature reduction methods, and provides a simple, low-cost, scalable alternative for producing metal-LIG composite with the least time-consumption without the use of any hazardous chemicals.
