Highly Increased Flow-Induced Voltage Generation on Hybrid Membranes of Monolayer Graphene and Single-Walled Carbon Nanotubes

Abstract:

We investigate the hybrid structure composed of single-walled carbon nanotubes (SWCNTs) and monolayer graphene to highly increase flow-induced voltage generation by an ionic droplet on these hybrid carbon membranes. These properties were characterized by Raman spectra, a field-emission-scanning probe, and optical microscope. We demonstrated flow-induced voltage generation on the hybrid structure at various ion concentrations of NaCl. The generated voltage for the membrane of SWCNTs/graphene/SWCNTs was 8.636 and 4.92 times larger than for the SWCNTs, and graphene/SWCNTs membranes, respectively, based on the highly increased electron dragging mechanism.
