摘要

Insulating materials are key components of power systems for the generation, transmission, storage, conversion and utilization of electrical energy. However, most insulating materials remain unsustainable and pose increasing environmental concerns. Developing sustainable insulating materials is therefore essential for achieving long-term sustainability in power systems. This Review summarizes the gas, liquid and solid insulating materials widely used in power systems and outlines strategies for improving their sustainability, including substitution, benign degradation, recycling, reuse and resource conversion. The Review also highlights the scientific and technological challenges in materials design, waste conversion and engineering applications, together with pathways involving policy frameworks, technology maturity and industry standards towards global net zero goals.
