| 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.

| 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. |
