摘要：Abstract
There is little doubt that nanomaterials are playing a key role in many technologies, and metallic nanoparticles are traditionally synthesized by wet chemical synthesis techniques where the chemicals used are quite often toxic and flammable. In this paper, we report green synthesis of silver nanoparticles using rice straw (RS) extract. The research includes two parts as follows: Firstly, using AgNO3 as the precursor and RS as reducing agent, PVP as protective agent, and controlling the reaction conditions, nano‐silver particles are generated by the liquid phase reduction method. The prepared Ag nanoparticles are examined by Malvern Zetasizer, scanning electron microscopy (SEM), transmission electron microscopy (TEM) with energy‐dispersive X‐ray spectroscopy (EDS), X‐ray diffraction pattern (XRD), and UV spectroscopy. The results show that the size of nano‐silver particles is controllable, they have good dispersion and appearance, and they are stable at long term storage. Finally, using nano‐silver as UV‐curing conductive filler, UV‐curing nano‐silver conductive ink is generated, and its conductive properties are discussed. Results show that the content of conductive filler has an effect on the resistivity of conductive ink.
