Abstract
100nm 이하의 공극, 10 내지 800㎏/㎥ 범위의 온도 및 10 내지 1500㎥/g 범위의 표면적을 갖는 폴리이소시아네이트를 주성분으로 하는 유기 에어로겔을 제공한다.
Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제 1 도 및 제 2 도는 에어로겔상의 BET 측정은 15㎡/g의 내표면적을 나타내었다. TEM 사진은 50nm의 공극을 나타내었다,
제 3 도는 100 내지 200마이크론 입자 크기의 조악한 분말로 분쇄된 수득된 에어로겔에 대해 압력(mbar)의 함수로서 열 전도도(10℃에서 mw/m°k 단위로의 람다값)을 보여준다,
제 4 도는 10 내지 20 마이크론 입자 크기의 분말로 분쇄된 동일한 에어로겔은 람다 대 압력 결과를 나타낸다.
