▎ 摘　　要

Silver (Ag)/chemically reduced graphene (Ag/CGN) composite succeeded prepared using a simple chemical reduction method. X-ray diffraction, Raman spectra, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy results revealed the formation of Ag and the reduction of graphite oxide to graphene during the synthesis process. Scanning electron microscopy observation showed that Ag particles were wrapped by graphene. The resistance of Ag/CGN circuits changed <10% when bended at a radius of 10 mm after 500 cycles and <15% when folded after 50 cycles, indicating the printed Ag/CGN fine circuits possess good electrical conductivity, flexibility and electrical stability under mechanical deformations. Furthermore, the Ag/CGN circuits exhibited high thermal stability, indicating its potential application for fabricating high performance flexible printed circuits.
