Photoinduced Atom Transfer Radical Polymerization Using Semiconductor Nanoparticles

Abstract

Photoinduced atom transfer radical polymerization of methyl methacrylate initiated by in situ generation of copper (I) complex from higher oxidation state species using neat zinc oxide and iron-doped zinc oxide nanoparticles is investigated. The polymerizations proceed in a well-controlled manner under UV light at room temperature as evidenced by kinetic and light on-off experiments. The evolution of molecular weight with conversion shows good correlations between experimental and theoretical molecular weights, which confirmed good control over polymerization along with a narrow molecular weight distribution.

Visible Light-Induced Atom Transfer Radical Polymerization for Macromolecular Syntheses

“…Yagci et al used ZnO nanoparticles as photocatalyst to initiate ATRP process (62). Zhou and co-workers reported surface-initiated ATRP mediated by irradiation of TiO 2 nanoparticles to reduce Cu(II) species (63).…”
