Abstract
Silver nanoparticles in hyperbranched poly(amine-ester) (HPAE) were prepared by means of NaBH4 reduction or UV irradiation. HPAE was found to play a key role in the formation of nanosized particles. Transmission electron microscopic (TEM) analysis showed that silver nanoparticles were spherical structure and homogeneously dispersed in HPAE with diameters of -45 nm (NaBH4 reduction) or -20 nm (UV irradiation). The absorption peaks due to the characteristic surface plasmon resonance of the obtained silver nanoparticles were observed at -420 nm in the ultraviolet-visible (UV-Vis) absorption spectra. FT-IR spectra confirmed that there were strong interaction between silver nanoparticles and HPAE, showing HPAE had proved to provide very effective protection to the stability of silver nanoparticles.
