The identification and characterization of structural membrane properties, including pores, topography, morphology, and surface interactions, that give essential information for various applications. In this article, we provide a characterization of the electrospinning waste Polyethylene Terephthalate (PET) by using the Atomic Force Microscope (AFM), Contact Angle (CA), X-ray Diffraction (XRD) and Differential Scanning Calorimetry (DSC) of Nanofibers. The data collected in this article is directly related to our previously published research article. The results were obtained to give information associated with the functionalized and surface modification of PET nanofibers. (C) 2020 The Author(s). Published by Elsevier Inc.
