Abstract

Composites of polyethylene oxide and multiwall carbon nanotubes (MWCNTs) were produced by mixing deagglomerated MWCNTs with PEO in solution, using a high-speed mixer. The deagglomeration was performed with high-intensity ultrasonic probe. DSC results show an increase in melting temperature with increase in amplitude of sonication. Also tensile test results show improved mechanical properties, with increased degree of deagglomeration of the nanotubes. SEM images show that the extent of nanotubes dispersion in the polymer matrix correlates with the extent of deagglomeration.
