Abstract

Recently, elastomer-nanocomposites reinforced with low volume fraction of nanofillers have attracted great interest due to their fascinating properties. The incorporation of nanofillers, such as, layered silicate clays, carbon nanotubes, nanofibers, calcium carbonate, metal oxides or silica nanoparticles into elastomers improves significantly their mechanical, thermal, dynamic mechanical, barrier properties, flame retardancy, etc. The properties of nanocomposites depend greatly on the chemistry of polymer matrices, nature of nanofillers, and the method in which they are prepared. The uniform dispersion of nanofillers in elastomer matrices is a general prerequisite for achieving desired mechanical and physical characteristics. In this paper, current developments in the field of elastomer nanocomposites reinforced with layered silicates, silica, carbon nanotubes, nanofibers and various other nanoparticles have been addressed.

최근에 나노충전제를 낮은 부피 분율로 보강한 엘라스토머-나노복합체는 흥미 있는 물성 때문에 관심을 크게 불러 일으켰다. 특히 층화 규산염 클레이(clay), 카본 나노튜브(carbon nanotube), 나노섬유, 탄산칼슘, 금속 산화물 또는 실리카 나노입자 등과 같은 나노충전제를 탄성체에 혼입하면 기계적 물성, 내열성, 동적 기계적 물성, 화염지연성, 차단성 등이 크게 향상된다. 나노복합체의 물성은 크게 고분자 기질, 나노충전제의 성질과 이들의 혼입 방법에 좌우한다. 탄성체 기질 내에 나노충전제들의 균일한 분산은 원하는 물리적 특성과 기계적 특성을 얻기 위한 일반적 필수조건이다. 본 논문은 층화 규산염, 실리카(silica), 카본 나노튜브(carbon nanotube), 나노섬유와 여러 가지 다른 나노입자로 보강된 탄성체 나노복합체의 현재 개발 현황을 소개하였다.
