Electrospun Mats Based on PVA/NaDDBS/CNx Nanocomposite for Electrochemical Sensing
This study presents a nanocomposite developed with PVA, multiwall carbon nanotubes (CNTs) doped with nitrogen, and NaDDBS, which change the electrical properties of the polymer and its viscosity to be used in electrospinning process for obtaining mats of nano/macro fibers. The proposed nanocomposite...
