Synthesis of Functional Nanoparticles for Application in Inkjet Printing

Abstract

Ag nanoflakes were synthesized by chemical reduction method using cetyltrimethylammonium bromide (CTAB) as a surfactant. The results of transmission electron microscope (TEM) analysis, ultraviolet-visible spectroscopic (UV-Vis) analysis, X-ray diffraction (XRD) analysis showed that the obtained Ag nanoflakes had size of ~50 – 60 nm, thickness of 16 nm, with flake shape reached 96 %. The particles crystallized in cubic structure of Ag. The Ag nanoflakes synthesized with pH = 4 were dispersed stably after 60 days from synthesis. The properties of the obtained Ag nanoflakes were suitable for using them as conductive particles in fabrication of functional inks for electrohydrodynamic printing technique.
