Abstract

Polystyrene-coated gold nanoparticles (molecular weight (Mn) of PS ∼ 1300 g/mol, average particle diameter d (core + shell) ∼ 9.2 ± 2.2 nm, corresponding to a high areal chain density of PS) are incorporated into symmetric poly(styrene-b-2 vinylpyridine) diblock copolymers with total Mn ∼ 60 000-380 000 g/mol at volume fractions of 0.07-0.32. For all Mn of diblock copolymers and particle filling fractions examined, particles are centralized in the PS domains with Gaussian distribution profiles. The distribution width generally decreases as the PS domain size decreases or as the particle weight fraction increases. These observations are discussed in terms of the relative entropic contributions of the polymer chains and particles.
