Production Methods andQuality Control

The two dominant production routes are CVD and solution-phase exfoliation. CVD grows graphene on copper or nickel foils at high temperatures (800–1,000 °C), then transfers the film to a target substrate. This yields the highest quality, with large single-crystal domains and minimal defects. Solution-phase methods—using chemical or thermal reduction of graphene oxide—are cheaper and scalable but introduce oxygen functional groups and structural defects that reduce thermal conductivity. Recent advances in flash Joule heating and laser-induced graphene are bridging the gap, producing films with conductivities >2,000 W/m·K at lower cost. Quality control remains critical: even small grain boundaries or wrinkles can create thermal resistance bottlenecks.
