| titleOfInvention | Electret elements |
| abstract | Mass produced polymeric materials, such as plastics sheet 1, often exhibit a residual electrostatic polarity which hitherto has been considered unwanted. The intensity of the resultant field is so low that it is of no practical use and is generally neutralized by the attraction to the sheet of contaminants such as dust. A useful electret element E1 is produced by coating a face of the sheet 1 with a thin layer of polymeric material 3 of opposite polarity. Such an element can be used succesfully for electrostatic 'pinning' because it exhibits an electrostatic field of greater intensity than that of the sheet 1 prior to coating. |
