2014 IEEE 15th International Symposium on Electrets ISE 15

Electrets and related phenomena continue to receive much interest both from the fundamentaland applied points of views. Charge storage in insulators is crucial for many applications, involves a wide range of materials (organic, inorganic, hybrid, powder, thin & thick films, bulk, porous, …) and, hence, is at the frontier of many scientific domains.The ISE is therefore a unique meeting opportunity for scientists and engineers from all over the world working in the field of electrical engineering, materials science and engineering, condensed matter physics and chemistry, and a chance for communicating about recent advances and research and development efforts in these areas. It also provides a forum for in-depth discussions between the most experienced and established scientists and engineers and young researchers.

For an improved design of high voltage apparatus a material with a low dielectric constant and a relatively high breakdown strength is advantageous. Therefore the insulating properties of polymer foam with closed pores are investigated. It was found, that for a foam with closed gas filled spheres the breakdown voltage is close to the partial discharge inception voltage and it ...

V. Altstadt; N. Behrendt; T. Frese; H. -W. Schmidt; R. Giesa; J. Hillenbrand; G. M. Sessler 2005 12th International Symposium on Electrets, 2005

Cellular polymer films are suitable for electret and piezoelectric applications. Considerable attention is currently focused on thermoplastic polymer foams such as isotactic polypropylene (i-PP). The cellular morphology leads to barrier effects effectively improving the charge storage stability. However, the application of neat cellular polypropylene electrets is limited due to their relatively low working temperature. Therefore, new research activities are mainly ...
