The effect of ligand molecular weight on nanoparticle dispersion and nanocomposite morphology has been investigated. Nanoscopic particles, CdSe/ZnS quantum dots (QDs), were dispersed into the polystyrene (PS) microdomains of a microphase separated, bulk PS-poly(methyl methacrylate) block copolymer. The QDs were compatibilized with the PS-domains of the microphase separated block copolymer by the use of PS-based ligands associated with the surfaces of the QDs. A stock solution of the functionalized particles ...
