Role of Grafted Chains for the in-situ Formation of Ag Nanoparticles within Poly(epichlorohydrin)-g-Polymethacrylate Films |
| 초록 |
Two kinds of amphiphilic comb-like copolymers, i.e. poly (epichlorohydrine)-g-poly(methylmethacrylate) (PECH-g-PMMA) and poly (epichlorohydrine)-g-poly (butyl metha crylate) (PECH-g-PBMA) were synthesized using atom transfer radical polymerization (ATRP). Nuclear magnetic resonance (1H NMR) and FT-IR spectroscopy presented the successful graft copolymerization by directly initiating the chlorine atoms of PECH macroinitiator. The amphiphilc comb-like copolymers were used as a template film for the in-situ growth of silver nanoparticles from AgCF3SO3 precursor using NaBH4. UV-visible spectroscopy and transmission electron microscopy (TEM) images clearly indicated that 1) Ag nanoparticles were selectively confined in the comb-like polymer films persisting microphase-separated morphology and 2) Ag nanoparticles (4 - 7 nm) formed in PECH-g-PBMA were smaller than those in PECH-g-PMMA (6 - 11 nm). This represents that the longer hydrophobic side chains in a comb-like copolymer is more effective in controlling the formation of metal nano particles. |
