摘要
以四氨基铜(锌)酞菁为四胺单体,与4,4'-二苯醚二胺(4,4'-ODA)和二苯醚四酸酐(ODPA)进行共聚,合成了聚(金属酞菁)酰亚胺.由于金属酞菁的引入,聚(铜酞菁)酰亚胺和聚(锌酞菁)酰亚胺的介电常数均高于传统聚酰亚胺(PI).以聚(铜酞菁)酰亚胺为基体,采用溶液共混的方法,制备了一系列碳纳米管/聚(铜酞菁)酰亚胺复合材料,碳纳米管较为均匀地分散在聚合物基体中.复合材料具有良好的介电性能,掺杂碳纳米管质量分数为20%的复合材料的介电常数达到200,介电损耗为2.25.
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.
