The interface between the filler material and polymer chains has been of interest to understand underlying principle in the changes of physical properties in inorganic/organic composite materials. In order to observe the interfacial behavior, we attempt to examine the movement of fluorescent probe near the surface of the filler. However, the localization of the probe is challenging; herein, we demonstrate the synthesis of fluorophore-attached polymer brush anchored on the surface of silica nanoparticles (SNPs) with a controlled size. The fluorophore attached telechelic PMMA and PS were synthesized by ATRP and CDI coupling. Immobilized alkyne functionality on SNPs allows grafting-to approach for the target structure. The resultants were thoroughly characterized with SEM, light scattering, XPS, and CLSM. Presented rational design of chemical route further highlight a feasible approach to build-up the composite materials with high complexities.
