## Abstract
Commercial graphene applications face a fundamental thermodynamic barrier: exfoliated sheets spontaneously re-aggregate into inert Bernal (AB) graphite when compounded into industrial polymer, metal, or ceramic matrices. This paper explores the physical mechanics of rotational lattice decoupling via high-energy electrothermal Flash Joule pulses exceeding 3,000 K followed by ultrafast quenching (>10⁴ K/s).

## Physical Mechanics
- **Lattice Misorientation**: Quenching recrystallizing sp² carbon sheets freezes adjacent layers into random rotational angles, eliminating the energetic well of AB stacking.
- **Interlayer Expansion**: Interlayer spacing expands from 0.335 nm in natural graphite to $d_{002} = 0.345–0.362$ nm in turbostratic graphene.
- **Raman Spectroscopic Verification**: Characterized under 532 nm laser excitation by a single, symmetric Lorentzian 2D band (~2700 cm⁻¹) with an absence of asymmetric Bernal doublets, verifying spontaneous, surfactant-free dispersibility.
