Synthesis, Characterization and Electrical Conductivity of Silver Doped Polyvinyl Acetate/Graphene Nanocomposites: A Novel Humidity Sensor

摘要

In the present study, we have synthesized conducting polymer nanocomposites consist of silver nanoparticles (AgNPs), graphene, and polyvinyl acetate (PVAc) emulsion. The synthesized nanocomposite was characterized by UV/Vis, FT-IR, XRD, TGA, and SEM techniques. SEM images showed that AgNPs and graphene sheets are well dispersed in the PVAc matrix. The electrical conductivities of the nanocomposites were examined using the impedance analyzer instrument. It was ascertained that polymer composite containing silver nanoparticles and graphene exhibit higher conductivities. The PVAc-AgNPs/Graphene nanocomposite was also used as potential conducting materials for humidity measurement.
