Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a polyphenylene ether material and its preparation method and application, in particular to a high dielectric polyphenylene ether material and its preparation method and application. Background technique [0002] Ceramic dielectric materials have many available properties, such as ferroelectricity, piezoelectricity, pyroelectricity, ferroelasticity, photoelasticity, electrostriction, and nonlinear optical properties. A material with a high dielectric constant means that it has good performance in storing electric energy and uniform electric field, and can be better used in devices such as small-volume, high-capacity microcapacitors, electronic computer memory elements, and thermistors. Although the ceramic dielectric has a high dielectric constant, it has disadvantages such as high molding temperature and brittleness, which limit its application. Polymers have the advant...
