| Outline of Final Research Achievements |
In this study, we aimed to develop polymerizable surfactants, which lead to stable surface functionalization. One of the polymerizable surfactants we synthesized was designed and synthesized to consist of a methacryloyl group, oligo(ethylene glycol) and a long alkyl group. The surfactant assisted the dispersion of gold nanoparticles in water. The polymerization of the surfactant on the gold nanoparticles did not affect the dispersion. After the polymerization, the gold nanoparticles kept the well dispersion state in water. The dispersion was not affected by washing the nanoparticles or by diluting the dispersion. The polymerization of the surfactant was also achieved on carbon nanotubes and improved the dispersion of carbon nanotubes in water. The present approach based on the polymerizable surfactant successfully realized non-detachable surfactant and stable surface functionalization.
