Block Copolymer-Nanorod Co-assembly in Thin Films: Effects of Rod-Rod Interaction and Confinement

Simulations and experiments of nanorods (NRs) show that co-assembly with block copolymer (BCP) melts leads to the formation of a superstructure of side-to-side NRs perpendicular to the lamellar axis. A mesoscopic model is validated against scanning electro ...
