MWCNTs/polymer/metal oxide composites fibers, where polyvinyl acetate (PVAc) is the base polymer and titania (TiO2) the metal oxide, have been prepared by the electrospinning technique. Composite samples with different MWCNTs loading were prepared and annealed in air at 600 °C. The morphological and microstructural properties of spun and annealed samples have been examined using XRD, TGA and SEM analysis. The electrical and oxygen sensing characteristics of the annealed composites have been evaluated, with the aim to study the effect of MWCNTs on the sensing behavior and develop oxygen sensors with enhanced performances.

Abstract
MWCNTs/polymer/metal oxide composites fibers, where polyvinyl acetate (PVAc) is the base polymer and titania (TiO2) the metal oxide, have been prepared by the electrospinning technique. Composite samples with different MWCNTs loading were prepared and annealed in air at 600 °C. The morphological and microstructural properties of spun and annealed samples have been examined using XRD, TGA and SEM analysis. The electrical and oxygen sensing characteristics of the annealed composites have been evaluated, with the aim to study the effect of MWCNTs on the sensing behavior and develop oxygen sensors with enhanced performances.File in questo prodotto:
