Progress in Nanodielectrics: Future From the Past Decade

Since the early 21st century, nanodielectrics have attracted significant attention. Initially regarded as exotic materials, they have since evolved into widely accessible advanced materials. Research has primarily focused on solid polymer nanocomposites and has recently expanded to include liquid nanocomposites, known as nanofluids. Over the past decade, considerable progress has been made in the field of nanodielectrics. To capture this progress, more than 400 papers published in the IEEE Transactions on Dielectrics and Electrical Insulation and IEEE Electrical Insulation Magazine between 2011 and 2023 have been collected and reviewed. The evaluation of host materials, guest nanoparticles, and their combinations has been carried out to identify those that deliver superior performance. Notable advances in microscopic studies of interphases and particle dispersions are highlighted. Applications in high-voltage (HV) equipment and power electronics devices are also referenced to promote further research in this area. In addition, it is important to recognize that machine learning (ML) plays a critical role in accelerating the research and development of nanodielectrics and their applications.
