Outline of Final Research Achievements

In this work, we examined the self-formation and -organization of gold nanoparticles on silica spheres using poly(ethylene oxide)-poly(propylene oxide) (PEO-PPO) block copolymers in solutions. The PEO-PPO block copolymers are expected to form the self-assembly on silica spheres due to the interfacial activity and amphiphilic characters of PEO-PPO block copolymers. In addition, gold nanoparticles would be formed in the self-assembled layers on silica spheres due to the reducing function of PEO-PPO block copolymers for tetrachloride gold(III) ions ([AuCl4]-) [Sakai et al., Langmuir, 2004; J. Colloid Interface Sci., 2012]. Indeed, gold nanoparticles were formed and organized on silica spheres by mixing of an aqueous [AuCl4]- solution with an aqueous PEO-PPO solution containing silica spheres. Furthermore, the formation and organization of gold nanoparticles on the silica sphere were controlled by reaction temperature, polymer type, solvent type and solvent quality.
