Surface‐induced ordering in block copolymer melts
G Brown, A Chakrabarti - The Journal of chemical physics, 1994 - pubs.aip.org
Surface-induced ordering in block copolymer melts is studied numerically. For symmetric
copolymers, the thickness of the surface-enrichment layer is found to scale as Req-NO with
B= O. 6, suggesting the system is undergoing a surface-induced strong segregation. The
density profile perpendicular to the interacting surface is described quite well by the form
predicted by Fredrickson in a mean-field analysis. In asymmetric copolymers, the surface is
found to have a profound effect on domain formation. For some otI-critical compositions …
