Morphological behavior of ABC mikto-arm terpolymer with a C60

POSTER

Abstract

We observed the morphological behavior of ABC mikto-arm terpolymer with a C60 additive. ABC mikto-arm terpolymers, consisting of polystyrene, polyisoprene and poly(2-vinylpyridine) (PS-PI-P2VP), with various P2VP volume fractions were examined. The role of C60 on the morphological behavior of mikto-arm terpolymer was studied by small angle X-ray scattering (SAXS) and transmission electron microscopy (TEM). The affinity of C60 to PS or P2VP was examined by neutron reflectivity. C60 can form charge-transfer complexes with electron donating pyridine groups in P2VP blocks. Before and after charge-transfer reaction, C60 showed different effects on the self-assembly of mikto-arm polymers. The domain spacing, interfacial width, and morphology of mikto-arm terpolymers were changed depending on the concentration of C60.
