Polymeric particles, particularly with polystyrene (PS), are commonly employed for spherical templates to be decorated by nanoparticles of metals, semiconductors, or oxides, which can be employed for applications in electronics, photonics, plasmonics, magnetics, and catalysis. However, surface modification is essential to attach nanoparticles to PS particles. We here demonstrate the direct formation of PS particles having the dopamine-functionalized surface from diblock copolymers containing dopamine units. By dissolving this amphiphilic diblock copolymer in water, spherical micelles were induced. Since these micelles have the PS cores with the dopamine-functionalized coronas, they can be considered as PS particles with dopamine-functionalized surface. Thus, without additional surface functionalization, we successfully decorated the PS particles, originated from the copolymer micelles, with Ag and TiO2 nanoparticles due to the dopamine functionality on the surface of PS particles. |
