ELEKTRETARTIKEL MIT HOHEM FLUORSÄTTIGUNGSVERHÄLTNIS
摘要
<p>An electret article that includes a polymeric material that has electric charge imparted thereto, that has a CF<SUB>3</SUB>:CF<SUB>2 </SUB>ratio of at least 0.15 and that has a fluorosaturation ratio greater than about 200. The electret article may be in the form of a porous web of polymeric fibers suitable for use as a filter. The inventive electret article is resistant to charge degradation upon exposure to high temperatures for prolonged time periods.</p>
