CZU 678.5:621.315.61
Injected and polarizing charges distribution was evaluated in the bulk of sodium butadiene rubber after polarization in the negative corona discharge. For this purpose a two-layered film was made consisting of sodium butadiene rubber and polyethyleneterephthalate. Electret properties of the material were measured before and after solvent removal of the rubber top-layer of various thickness.
Keywords: heterocharge, homocharge, rubber, corona electret.
