以下に本発明の各実施例を表にして示す。
The present invention relates to self-recovering capacitors. Conventional self-supporting capacitors are formed by depositing metals such as Al or Zn on one or both sides of an insulating paper or film, and then winding or laminating them. Depending on the type of capacitor, the self-recovery action progresses very well in some cases, while in others it does not progress well and results in local or total destruction of the capacitor, and even with the same type of capacitor currently in use, self-recovery action progresses very well. If the performance is improved, it is possible to improve the potential gradient used. Capacitors using polystyrene or polyvinylidene fluoride as dielectrics are examples of the latter, and this type of capacitor has not been put into practical use. As a result of various experimental studies regarding the self-healing effect of capacitors, the present inventor found that an extremely good self-healing effect was obtained by forming (SN) It was confirmed that the amount of free carbon at that site was extremely small. The above insulating film is a plastic film.
Examples include insulating films of polystyrene, polyethylene, polypropylene, polycarbonate, polyethylene terephthalate, polyethylene naphthalate, polybutylene terephthalate, polyvinyl fluoride, polyvinylidene fluoride, polyamide, polyamideimide, and the like. In addition, the electrodeization of (SN) x polymer onto a film can be achieved by vacuum evaporation. Note that the vacuum deposition conditions are related to the physical properties of the dielectric, and therefore vary depending on each dielectric, but must be performed under conditions that do not cause deterioration of the (SN) x polymer. Examples of the present invention are shown below in the form of a table.
