Silver ions of poly(vinyl chloride)-g-poly(styrene sulfonic acid) (PVC-g-PSSA) graft copolymer were reduced to form silver nanoparticles under thermal condition (80°C). We were successful in synthesizing silver nanoparticles with various size and morphologies by changing reaction time. At short reaction times (∼1 h), silver nanoparticles with 5 nm in size were formed withoutchanging of microphase-separated structure of graft copolymer. At medium reaction times (∼5 h), silver nanoparticles were aggregated to form large clusters ranging 30∼50 nm in size. At much longer reaction times (∼18 h), hurricane-like silver clusters were observedbecause of thestrong particle aggregation. |
