Abstract

Recently supramolecular network thermo-reversible crosslinking elastomer having flexibility, various functionality, and advantages of thermoplastic elastomer (TPE) such as recycle and easy processbility is introduced. Although thermo-reversible bonds such as hydrogen bond and ionic cluster is recognized as a common technology since 1990, control technology of bonding and dissociation of crosslink in supramolecular network is a recent technology. In this review, characteristics of thermo-reversible crosslinking elastomer having rheological properties of TPE and reinforcing behaviors of thermoset elastomer are summarized.

최근에 기존 고무의 장점인 유연성과 충전제에 의한 다양한 기능성과 열가소성 고무의 장점인 리싸이틀 및 성형의 용이성을 동시에 갖춘 초분자 네트워크형 열가역성 가교 탄성체가 소개되고 있다. 수소 결합과 이온 클러스터간의 결합력과 같은 열가역성 결합은 1990년부터 소개되었지만, 초분자 네트워크에서 가교 구조의 결합과 절단을 조절할 수 있는 기술이 시도된 것은 최근의 기술적 성과이다. 본 보문에서는 열가소성 탄성체의 용융 특성과 가교 탄성체의 보강 거동을 가지는 열가역성 가교 탄성체의 특징들을 정리하였다.
