Insulated wire and preparation method thereof, coil and electronic/electrical device

Abstract

An insulated wire includes a conductor and an insulation layer arranged on an outer periphery of the conductor, where a material of the insulation layer is obtained by blending and pelletizing a resin A and a resin B. The material obtained by blending contains units as shown in Formulae 1-3: where a molar ratio of the unit shown in Formula 1 is 3%-17%, a molar ratio of the unit shown in Formula 2 is 37%-77%, and a molar ratio of the unit shown in Formula 3 is 20%-47%. The present disclosure can improve the adhesion between pure PEEK resin and copper conductor and enhance the flexibility of the insulation material. Moreover, since both PEK-C and PEEK belong to the polyaromatic ketones, and have the same ether bonds and ketone groups, they exhibit good compatibility.
