摘要：
Nanocomposites of Sulfonated Poly(Aryl ether ketone) (SPAEK) and functional multiwall carbon nanotubes (a-MWNTs) were fabricated by a solution method. The results showed that the composites exhibited a higher dielectric constant that was near 600 when the volume fraction of carbon-nanotubes was 0.07 (7 vol%) at 10(3) Hz. The percolation threshold of the a-MWNTs/SPAEK composites was only 3 vol% of a-MWNTs, and the dielectric constant could reach 210. The dielectric constant of composites changed little with frequency increase when the content of carbon nanotubes was more than 3 vol%, and the composites could keep high dielectric constant at high-frequency (> 200, at 10(6) Hz).
