High-performance electret and air filter. |
摘要 |
<p>Disclosed is a high-performance electret comprising 60 to 99% by weight of a non-polar polymer, 0.5 to 39.5% by weight of a polar polymer and 0.5 to 20% by weight of at least one component selected from the group consisting of (A) a non-polar polymer modified with an unsaturated carboxylic acid or a derivative thereof, (B) a non-polar polymer modified with an unsaturated epoxy monomer and (C) a non-polar polymer modified with a silane monomer having an olefinically unsaturated bond.</p><p>In this electret, a high charge density can be maintained stably over a long period, and this electret can be easily formed into a film. An air filter prepared from this electret is very excellent in the dust collecting efficiency.</p> |
