Sombel Diaham

University of Toulouse

Sombel Diaham obtained an MSc and Ph.D. in Electrical Engineering from the University of Toulouse, France, in 2005 and 2007, respectively. In 2008, he joined the Laboratory on Plasma and Conversion of Energy (LAPLACE) as an associate professor. He is an expert in electrical isolation for HV power and integrated electronics. He works on polymer films, thin inorganic layers, and encapsulation resins. His interests concern the physics of dielectrics (charge injection, breakdown mechanisms), electrical characterizations, properties-process relationships, modeling and multi-stress aging of insulation, and the application to real devices. Dr. Diaham develops advanced composites and nanocomposites to enhance devices’ and systems’ reliability. In this role, he designs field grading composites tailored by (di)electrophoresis and applies them to power electronics isolation.

Polyimide is one of the most efficient polymers in many industries for its excellent thermal, electrical, mechanical, and chemical properties as well as its easy processability. In the electronic and electrical engineering industries, polyimide has widely been used for decades thanks to its very good dielectric and insulating properties at the high electric field and at high temperatures of around 200°C in long term-service. Moreover, polyimide appears essential for the development of new electronic devices where further considerations such as high power density, integration, higher temperature, thermal conduction management, energy storage, reliability, or flexibility are required in order to sustain the growing global electrical energy consumption. This book gathers interdisciplinary chapters on polyimide in various topics through state-of-the-art and original ongoing research.
