Abstract

See full text

The invention discloses a carbon nanotube/polyetherimide/thermosetting resin dielectric composite and a preparation method therefor. 100 parts by weight of polyetherimide and 1-7 parts by weight of carbon nanotube are mixed uniformly in an Haake torque melt cavity to obtain a carbon nanotubes/polyetherimide composite; 20 parts of the carbon nanotube/polyetherimide composite are dissolved in 100-150 parts of dichloromethane, then the mixed solution is added in 100 parts of molten thermocurable thermosetting resin, mixing, and heat preserving, stirring are performed until a mixture is formed in a uniform state, and curing and post-treating are performed to obtain a carbon nanotube/thermosetting resin dielectric composite, wherein the substrate thereof has a typical reverse phase structure, while the carbon nanotubes are dispersed in a polyetherimide phase. The composite has a relatively low percolation threshold, a high dielectric constant and a low dielectric loss. The preparation method of the present invention has a simple process and is suitable for large-scale production.
