연구분야

연구개요
고분자는 반도체, 전자, 자동차, 섬유, 통신, 건축부품 등 우리의 실생활에서 매우 광범위하게 사용되고있다. 본 실험실에서는 신규 엔지니어링 플라스틱 중합공정과 에틸렌 공중합 고분자 생산공정 개발을 위해 고분자용액의 상거동을 연구한다. 또한 여러가지 고분자와 유/무기소재 (nano입자 등)를 compounding하여 새로운 복합소재를 개발한다

연구과제

• 신규 엔지니어링 플라스틱 중합공정
• 에틸렌 공중합 고분자공정
• 고분자 용액의 고압 상거동
• 초임계유체를 이용한 고분자의 분자량 및 조성에 따른 분리/정제
