Dielectric properties of carbon-nanotube/amino-functionalized poly(arylene ether ketone) composites

摘要

Novel a-MWNTs/NH2PAEKK nanocomposite, with a high dielectric constant, low dielectric loss and high breakdown field, were prepared to use a solution blending technique. The uniform dispersion of a-MWNTs in the NH2PAEKK matrix was realized. The dielectric constant of percolating nanocomposites (the a-MWNTs volume fraction of 0.09) was as high as 60 at 10~3 Hz, it was about 20 times larger than the dielectric constant of NH2PAEKK, and the breakdown field was near 4l.4MVm~(-1).For f_(a-mwnts )
