Preparation of nanocomposites fibers via PVA/natural nanomaterial

Abstract

The aim of this study is to manufacture a nanocomposite of mechanically ground nano red chicken eggshells and PVA polymer with 10% conc. and using five ratios of eggshell nanoparticles like (0.004, 0.005, 0.006, and 0.007) gram. There are many testes like tensile strength, scanning electron microscopy (SEM), Fourier Transform Infrared (FTIR) Spectroscopy and   thermal differential scanning (DSC) tests are performed on the resulted nanocomposite threads. Use Electro spinning technique Nano fibers reinforced with nanoparticles are prepared. Results of SEM proved that the nanofibers diameter decreases with increasing the nanoparticles ratio, FTIR results showed that there are a physical reaction between the nanofibers and nanoparticles without any chemical reaction. DSC results proved that increasing the glass transition temperature with increasing the nanoparticles ratio. Tensile strength of nanocomposites fibers increases with increasing the nanoparticles ratio as well as the plastic deformation of nanofibers appeared.
