An approach for the preparation of silver nanoparticle-reduced graphene oxide/polyurethane composites
(AgNP@RGO/PU) was proposed. An electrospinning process was utilized to fabricate a lightweight and
flexible PU fiber mat. Graphene oxide (GO)/PU composites were prepared using a dip-coating method.
Thus there happens a hydrogen bonding interactions between the GO sheets and PU fibers. 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 (
