Nylon 1/polyvinylidene fluoride composite dielectric film and preparation method thereof

Abstract

The invention provides a nylon 1 / polyvinylidene fluoride composite dielectric film and a preparation method thereof, and relates to the technical field of composite materials. The film is prepared from the following components in percentage by weight: 80 to 99 percent of polyvinylidene fluoride and 1 to 20 percent of nylon 1. The invention further provides a preparation method of the nylon 1 / polyvinylidene fluoride composite dielectric film. The preparation method comprises the following steps: mixing polyvinylidene fluoride and nylon 1, and mixing on a torque rheometer at 180-200 DEG C for 10-20 minutes; and carrying out hot pressing on the mixed product on a press vulcanizer at 180-200 DEG C for 10-20 minutes, and maintaining the pressure at room temperature for 3-10 minutes to obtain the nylon 1 / polyvinylidene fluoride composite dielectric film. The dielectric constant of the polyvinylidene fluoride is improved, the dielectric loss of the polyvinylidene fluoride is kept at a low level, various problems caused by poor compatibility are reduced, and therefore the functional characteristics of the polyvinylidene fluoride are improved.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a nylon 1 / polyvinylidene fluoride composite dielectric film and a preparation method thereof. Background technique [0002] With the rapid development of electronic information technology, the miniaturization and weight reduction of electronic components have put forward higher requirements for the integration, safety and life of the device. Therefore, the development of materials with higher dielectric constant and lower dielectric Electrically lossy polymer dielectric materials have broad application prospects. Traditional ceramic dielectric materials have a high dielectric constant, but high molding temperature, difficult processing, and low impact resistance limit their application in the field of dielectric materials. [0003] Polymer-based dielectric composites have the advantages of good processability, low dielectric loss, and high dielectric constant, so the...
