Nanophase-Separated Structures of Hydrogen-Bonded Interpolymer Complexes of AB Block Copolymer/C Homopolymer in Thin Film with Variable Blending Composition upon Solvent Annealing
Abstract:The self-assembly behavior of hydrogen-bonded interpolymer complexes of poly(styrene)-b-poly(4-vinylpyridine) (PS-b-P4VP)/poly(4,4 -oxydiphenylenepyrome llitamic) acid (POAA) in thin films with variable POAA weight content upon solvent annealing in benzene/N-methy1-2-pyrrolidone (NMP) mixture vapor was investigated.It was found that when the PS-b-P4VP/POAA thin film blends were annealed in a benzene/NMP (0.97/0.03, in volume) mixture vapor, the thin film blends with a high POAA wt%, above 40%, exhibited a mixt… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
