Block Copolymer Self-Assembly (2D)

Interactive 2D Cahn-Hilliard / Ohta-Kawasaki phase-field simulator: watch a diblock copolymer film microphase-separate into a lamellar, cylinder or sphere cross-section pattern as you tune the A-block volume fraction — the same physics that drives directed self-assembly nanolithography.

Diblock copolymer films spontaneously organize into nanoscale stripes, dots or a mix of the two purely from the interplay of chemical demixing and chain connectivity — no external template required. This 2D companion simulator solves the same Ohta–Kawasaki phase-field equation as the 3D version, on a flat cross-section, letting you tune the A-block volume fraction, the Flory–Huggins segregation strength χN, and the long-range domain-spacing coefficient α, then watch the film anneal in real time toward the periodic morphology those parameters predict.

⚙ Under the hood

Simulate a diblock copolymer melt microphase-separating into lamellae, cylinders or spheres using the Ohta-Kawasaki phase-field model, the physics behind directed self-assembly nanolithography.
