    Flash Joule heating (FJH) produces turbostratic graphene (tFG) from carbon black. This method offers a scalable route to high-quality tFG, avoiding harsh chemical or mechanical pre-exfoliation steps.

    Area of Science:

    • Materials Science
    • Nanotechnology
    • Physical Chemistry

    Background:

    • Flash Joule heating (FJH) is a method for producing graphene from various carbon precursors.
    • Understanding the morphology and properties of flash graphene (FG) is crucial for its applications.

    Purpose of the Study:

    • To investigate the morphologies and properties of flash graphene (FG) derived from carbon black using FJH.
    • To determine optimal FJH parameters for generating high-quality turbostratic graphene (tFG).

    Main Methods:

    • Flash Joule heating (FJH) of carbon black.
    • Characterization of flash graphene (FG) morphologies (turbostratic FG and wrinkled graphene).
    • Atomistic simulations to compare FJH with generic thermal annealing.

    Main Results:

    • FG produced from carbon black consists of turbostratic FG (tFG) and wrinkled graphene.
    • Optimal FJH duration for high-quality tFG is 30-100 ms.
    • Extended FJH (>100 ms) leads to bulk graphite formation.
    • Atomistic simulations show FJH promotes graphitic plane alignment, unlike thermal annealing.
    • tFG is readily exfoliated via shear.

    Conclusions:

    • FJH is a promising method for bulk production of high-quality turbostratic graphene (tFG).
    • The process avoids the need for chemical or high-energy mechanical pre-exfoliation.
    • Tailoring FJH duration is key to controlling the resulting graphene structure.
