摘要：
Focusing on good dispersion of carbon nanotube (CNT) in the polymeric matrix, morphological and theological properties as well as electrical conductivity of poly(vinyl acetate) (PVAc)/multi-walled carbon nanotube (MWNT) nanocomposites were investigated. Electrical properties of the PVAc/MWNT nanocomposites were examined using a resistometer. Small amount of MWNT was observed to remarkably decrease resistivity of the nanocomposites. Internal structure of the nanocomposite materials was characterized by transmission electron microscope. Raman spectroscopy was adopted to investigate molecular motion of CNT in the composites. Moreover, theological properties of the nanocomposites were measured using a rotational rheometer, observing increased storage (G') and loss moduli (G '') as a function of frequency in an oscillatory shear mode.
