 In this study, the production of weight ratios of 1, 3 and 5 % multi-walled carbon nanotube
reinforced / unreinforced polyvinyl alcohol (PVA) nanofiber mats was carried out by electrospinning method.
Tensile strength, modulus of elasticity and elongation amounts were investigated by tensile tests under static
loading with / without reinforced nanofiber mats. % 1 MWCNT reinforced PVA nanofiber mats, ç
, E and
toughness increased by 50, 88 and 12 %, respectively, when compared with PVA nanofiber mats. Fourier
Transform Infrared Spectroscopy (FT-IR) and Differential Scanning Calorimetry (DSC) analyzes were
performed on the chemical changes and interactions occurring in the system formed by combining the
produced nanofiber mats with PVA and MWCNT. In addition, scanning electron microscope (SEM) images
were also investigated to determine the physical properties of reinforced / unreinforced PVA solutions and to
monitor the surface porosity of networked polymers at the specification of nanofiber mats.
