Formation of Ag Nanoparticles in Polystyrene-b-Poly(oxyethylene methacrylate) Membranes |
| 초록 |
A diblock copolymer of polystyrene-b-poly(oxyethylene methacrylate) (PS-b-POEM) was synthesized via atom transfer radical polymerization (ATRP). The self-assembled block copolymer membrane wasproducedand used to template theformation of silver nanoparticles in the solid state by the introduction of AgCF3SO3 precursor and UV irradiation process. Transmission electron microscopy (TEM) and UV-visible spectroscopy confirmed the in situ formation of silver nanoparticles within the block copolymer membranes, and the size of nanoparticles were controlled by adjusting the moiety of hydrophilic POEM domains. PS-b-POEM block copolymer with a lower POEM content was effective in generating smaller size ofsilver nanoparticles. |
