Abstract

The invention belongs to the technical field of polymer based nano composite materials and preparation methods thereof, and particularly relates to a polyarylether ketone / carbon nanotube composite material with a high dielectric property and a preparation method thereof. The composite material consists of functionalized polyarylether ketone and carbon nanotubes, wherein in terms of the summation (100 percent) of the volume fractions of the functionalized polyarylether ketone and the carbon nanotubes, the carbon nanotubes account for 0.5 to 20 percent and the balance of the functionalized polyarylether ketone. Specifically, the carbon nanotubes (unmodified carbon nanotubes and carboxylic acid modified carbon nanotubes) as modified filling materials, the functionalized polyarylether ketone (sulfonated polyarylether ketone, amino functionalized polyarylether ketone and cyano functionalized polyarylether ketone) as base materials, and a method for solution blending is adopted to prepare the functionalized polyarylether ketone / carbon nanotube composite material with the high dielectric property, and simultaneously solve the problems of high dielectric loss, over-high loading level, reduced processability and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer-based nanocomposite materials and their preparation, and in particular relates to a polyaryletherketone / carbon nanotube composite material with high dielectric properties and a preparation method thereof. Background technique [0002] Polymer dielectric material is a material with a very broad application prospect. Because of its good performance of storing electric energy and uniform electric field, it has very important applications in the electronics, motor and cable industries. [0003] The development of the microelectronics industry depends on the progress of integrated circuit (Integral Circuit, IC) technology, and the development of electronic packaging technology promotes the progress of IC technology. The development of electronic packaging technology can be divided into three generations: discrete component packaging, chip-scale packaging and system packaging. Among them, the system pa...
