The complexes of perfluorooctanoic acid (PFOA) and polystyrene-b-poly-(4-vinylpyridine) (PS-b-P4VP) can induce micellization of the block copolymer in their common solvent chloroform. Rod-like and ellipsoidal aggregates form respectively by micellization. When the concentration of block copolymer is 1.0 g/L, DLS and SEM measurements were used to characterize their aggregation and morphology under the molar ratio of PFOA to the pyridine rings (MR) being 1/30 to 1/10. It is unexpected that the complex still self-assembles into stable aggregates even when the MR value is as low as 1/30. The different morphologies of the aggregation can be found by using SEM during the change of the MR value.

Key words: perfluorooctanoic acid, polystyrene-b-poly-(4-vinylpyridine), micellization
