초임계이산화탄소 에멀젼과 그 응용
A Study on the Supercritical Carbon Dioxide Emulsion and Its Application
E-mail:
초록
최근 국내에서 초임계유체기술에 대한 관심이 매우 높아지고 있다. 추출/정제, 반도체세정, 기능성구조체, 약물전달체, 금속산화물 나노입자제조, 물성데이터구축 등의 분야에서 초임계유체기술 개발이 앞으로 본격적으로 진행되고 심화될 전망이다. 초임계유체기술 중 초임계에멀젼에 관해서는 그 필요성을 절감하여 국제적으로 활발히 연구가 진행되지만 국내에서는 아직 이에 대한 연구가 미미한 상태이다. 초임계에멀젼은 주로 무극성을 띤 이산화탄소 유체에 적용되어 극성물질과의 응용력을 높이는데 연구 목적을 두고 있다. 본 고에서는 초임계이산화탄소를 이용한 매크로/마이크로에멀젼에 대한 상세한 설명과 이를 응용한 연구를 중점적으로 소개하여 이에 대한 연구 활성화를 도모하고자 한다.
Recently, the supercritical fluids technologies have been paid extremely increasing attention in the country. From now on, the supercritical technologies such as extraction/purification, SCORR (supercritical carbon dioxide photo-resist removal), DDS (drug delivery system), formation of functional structure of polymer or ceramic materials, preparation of metal oxide nano-particles, construction of database (DB), etc., will be investigated and developed more actively. The study on the supercritical emulsion among supercritical fluid technologies has been performed rigorously in advanced countries by recognizing its importance, however, a few researches are on progress in the country. The purpose of researching supercritical emulsion is mainly focused on the non-polar supercritical carbon dioxide and enhancing its application with polar substances. In this article, we are aimed to promote the research foundation of supercritical emulsion by reviewing in detail the supercritical CO2-macro/microemulsion and by introducing preponderantly the researches about its application.
