Abstract
To improve compatibility of multi-walled carbon nanotubes (MWCNTs) with polymer matrix, chloride-functionals were applied to the MWCNTs by functionalization using HNO3/H2SO4 and thionyl chloride. The MWCNTs were conjunct by poly vinyl alcohol (PVA) surface via ionic mechanism using benzoyl peroxide (BPO) in water during a high temperature refluxing process. The results of Fourier transform spectrometer (FT-IR) and field emission scanning electron microscopy images (FE-SEM) confirmed the linkage of the MWCNTs to the PVA via a covalent bond and the attributes of MWCNTs-PVA nanocomposite were recognized by electrical conductivity (EC), disperse stability measurements and thermogravimetric analysis (TGA).
