My own research:
1. Small flake, high-edge detonation graphene (20–50 nm, 3–9 layers)
Pros: High edge/defect density → direct covalent chemistry (carboxylation, amide coupling, silanization) possible with fewer pre-steps. Large specific surface area → high loading of functional groups. Vendor-sold “Reactive Shell” already gives —COOH handles, speeding integration into composites/bioconjugation.
Cons: Small flakes may aggregate differently, change rheology in slurries, and if produced in an uncontrolled detonation quench may have batch variation; some post-purification is often required to remove soot/byproducts.
2. Plasma/gas-cracked graphene (tuneable, low-defect)
Pros: Clean baseline, tunable platelet size, highly reproducible in controlled reactors; post-plasma functionalization lets you tune O/C or N/C precisely with controlled power/time/gas composition —
