【Abstract】 Electric wires and cables are an important part of power transmission, signal transmission, electrical appliances and other fields. With the continuous development of transportation, aerospace and other industries, the cable part puts forward stricter requirements for materials. Polyimide(PI) is a class of high-performance materials. It is wildly used in motor insulation, aerospace, microelectronics, etc. due to its self-extinguishing, light weight, excellent high and low temperature resistance, electrical insulation properties and mechanical properties. However, its better application in the field of cables has attracted tremendous interests in recent years. The application of polyimide for cables and hot issues in the fields of enameled wire, aviation cable, high-temperature superconducting cable and other fields of cable is introduced. Detailed introduction of research progress of the preparation and modification of polyimide for the above applications is given. Finally, the future research and development direction of polyimide wires and cables are prospected.更多还原
