Abstract

Control of the incorporation behavior of Au nanoparticles grafted with polystyrene (PS) in an ABC triblock terpolymer composed of PS, polyisoprene (PI) and poly(methyl methacrylate) (PMMA) with double-helical morphology was investigated by transmission electron microtomography and three-dimensional structural analysis. The assemblies in the microdomains were controlled by varying the molecular weight of the PS molecules grafted on the Au nanoparticles. For PS-grafted Au nanoparticles >0.3 times the domain dimension of the PS microdomain in the poly(styrene-b-isoprene-b-methyl methacrylate) (SIM) film, the nanoparticles were located at the center of the PS microdomains to minimize the entropy loss of the PS segment of SIM. In contrast, Au nanoparticles
