Abstract
The present thesis includes preparation, characterization and studying of the structural changes of polymeric blend and polymeric blend containing Li salt.
The first part concern: ”Characterization and physical properties of PVC/PMMA polymer blends” and the second part for: ”Physical properties of PVC/PMMA polymer blend with different concentrations of lithium titanium oxide nanoparticles ( LTO-NPs) dopant ”. These films have been prepared by casting technique while different techniques had been used to investigate both the two systems. Experimental studies such as Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) for structural investigation, Ultraviolet and visible (UV/Vis.) spectroscopy for optical properties, DC conductivity for electrical properties, Scanning electron microscopy (SEM) and Transmission electron microscopy for morphology detections.
from structural, morphological, optical, electrical and spectroscopic investigations for the two systems we find that:
The ratio (70/30 wt%) of PVC/PMMA polymer blends was preferred to be used in some practical applications to add appropriate filler on it, such as lithium salt, because of its unique properties.
All previously mentioned techniques suggest that LTO-NPs modify the physical properties of polymer blend (PVC/PMMA). Also, it enhances the optical, electrical properties of polymer.
All results suggest that investigated samples can be used in some applications like lithium batteries which is the main purpose of this thesis.
