Rising of Dynamic Polyimide Materials: A Versatile Dielectric for Electrical and Electronic Applications.

Polyimides (PIs) are widely used in circuit components, electrical insulators, and power systems in modern electronic devices, large electrical appliances, and aerospace applications. Electrical/mechanical damage and atomic oxygen corrosion of materials are important factors that threaten reliability and service lifetime. Dynamic (self-healable, recyclable and degradable) PIs, a promising class of materials that successfully improve electrical/mechanical properties after damage, are anticipated to solve this issue. We share our viewpoints and perspectives on the status and future trends of dynamic PI based on a few existing documents. The main damage forms of PI dielectric materials in the application process are first introduced, and initial strategies and schemes to solve these problems are proposed. Fundamentally, the bottleneck issues faced by the development of dynamic PIs are indicated, and the relationship between various damage forms and the universality of the method is evaluated. The potential mechanism of the dynamic PI to deal with electrical damage is highlighted and several feasible prospective schemes to address electrical damage are discussed. We conclude by presenting a short outlook and future improvements to systems, challenges, and solutions of dynamic PI in electrical insulation. The summary of theory and practice should encourage policy development favoring energy conservation and environmental protection and promoting sustainability . This article is protected by copyright.
