A powerful reducing agent, hydriodic acid, was used to reduce GO/PU composites which transforms into RGO/PU
composites. The composite exhibited low electrical resistance (3.5 102 U/sq) because of reduction
reaction. Furthermore, AgNPs, which were modified with thiophenol, were deposited on the RGO/PU
composite through pep interactions between the aromatic functional groups on the AgNPs and the RGO
by a dip-coating method. The obtained AgNP@RGO/PU composite exhibited a remarkably enhanced
electrical property (
