Inorganic nanoparticles (NPs) have been investigated in various areas due to their fascinating features. Au NPs are attracting much attention due to their good susceptibility to surface modification through the use of various thiol-terminated ligands. Thus, Janus Au NPs can be easily synthesized via tuning the surface property of Au NPs with two different ligands. We were able to successfully synthesize thermally stable Janus Au NPs with thiol terminated polystyrene (PS) and poly(methyl methacrylate) (PMMA). To characterize the Janus properties of Au NPs, we investigated the location of the NPs in lamellar forming PS-b-PMMA. However, it is hard to confirm phase behavior of the ligands on the Au NPs. Herein, we prepared Janus Au NPs using deuterated PS and PMMA, and normal Au NPs using dPS-r-PMMA ligands of various lengths for small angle neutron scattering (SANS) study. As the ligands’ characteristics are changed, the phase behaviors of the ligands on the Au NPs are different. |
