Characterization of Polyvinyl Acetate/Multi Walled Carbon Nanotube Nanocomposites

Abstract

Nanocomposite films from polyvinyl acetate (PVAc) dispersion and multi walled carbon nanotubes (MWCNTs) were prepared by solution casting technique. Stress-strain properties showed increase in elastic modulus and yield strength. Mechanical properties characterized by dynamic mechanical thermal analysis represented increase in storage modulus below glass transition temperature. Studied dielectrical properties of PVAc/MWCNT nanocomposites revealed formation of conductive MWCNT network in PVAc matrix.
