Preparation and Dielectric Properties of a-MWNTs/Poly ( metal phthalocyanine) imide Copolymers
摘要
Abstract
Poly (metal phthalocyanine) imide copolymers [P(MPc)I] were prepared with tetra-phthalocya-nine 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 nano-tubes/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.关键词
