Adsorption and ordering of amphiphilic rod–coil block copolymers on a substrate: conditions for well-aligned stripe nanopatterns

Author affiliations

Abstract

Controlling the ordering of self-assembled nanostructures is vital in block copolymer nanotechnology but still presents a challenge. Here we demonstrated that the adsorption and ordering of amphiphilic rod–coil block copolymers on a substrate can generate well-aligned stripe nanopatterns by dissipative particle dynamics simulations. The effects of the copolymer concentration and the surface affinity on the formation of stripe nanopatterns were examined. The simulation results revealed that the well-aligned stripe nanopatterns with controllable thickness and stripe width can be obtained in the systems with higher copolymer concentration and surface affinity. An immersion coating experiment was designed to verify the simulation results, and an agreement is shown. The present work provides a strategy for constructing well-aligned stripe nanopatterns in a controllable way.
