doi:10.3969/j.issn.0251-0790.2012.07.042

Abstract

Abstract: Poly(metal phthalocyanine)imide copolymers [P(MPc)I] were prepared with tetra-phthalocyanine teraamines(4NH₂-MPc), 4,4'-diamino diphenyl ether(4,4'-ODA), and 4,4'-oxydiphthalic anhydride(ODPA). The dielectric constants of the polymer are higher than traonditional polyimide(PI). Carbon nanotubes/poly(copper phthalocyanine)imide [a-MWNTs/P(CuPc)I] composites with different contents of carbon nanotubes were prepared using solution method. Carbon nanotubes show good dispersion in P(CuPc)I matrix. The composite containing 20% carbon nanotubes have high dielectric constant of ca. 200 and low dielectric loss of ca. 2.25(at 1 kHz) which show good dielectric properties.
