2D CNT Nanocomposite Percolation Sheet

Scatter carbon-nanotube-like rods across a 2D cross-section of a polymer film and watch electrical percolation happen live: as the filler area fraction φ rises, more excluded area overlaps between rods, more clusters merge, and past a critical threshold φ_c a single connected path spans the whole sheet — the moment the composite turns from an insulator into a conductor. 2D continuum percolation is governed by its own universal constant (Widom/Balberg's N_c⟨A_ex⟩/A ≈ 5.637), distinct from the 3D case, so the network you see here is a genuine 2D physical system — a thin conductive film — not a flattened 3D scene. Drag the canvas to pan and scroll to zoom in on individual junctions; the aspect-ratio and alignment controls reproduce the same materials trend as the paired 3D simulator.
