Description

엘렉트레트 필터
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 순수에 의한 습윤(wetting)시의 접촉각을 측정하기 위한 수적(liquid droplet)법을 설명하는 도면,
제2도는 실시예 1∼15와 비교예 1∼15에서 제조된 필터 샘플의 담배연기 흡착성능을 시험하는데 사용되는 장치의 개략도,
제3도는 상기 필터 샘플들의 포집효율을 측정하는데 사용되는 장치의 개략도.

Claims (3)

  1. 순수에 대한 습윤시의 접촉각이 95°이상인 수지로 제조된 엘렉트레트 필터.
  2. 실리콘오일의 배합에 의하여, 순수에 대한 습윤시의 접촉각이 95°이상으로 조정된 수지로 제조된 엘렉트레트 필터.
  3. 제2항에 있어서, 상기 실리콘오일 함유량이 0.05∼5중량%인 엘렉트레트 필터.
    ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.
