CNT와 비교하여 그래핀 복합체를 사용하는 경우 경제적 측면의 장점은? | 반면에 CNT는 이를 처리하기 위해 일반적으로 표면개질2)을 요구한다. 또한 상대적으로 생산이 쉽고 저렴하며 CNT에 비해 인체에 덜 유해하다.22) 이러한 장점과 우수한 특성의 관점에서, 강화된 그래핀-세라믹 복합체는 큰 가능성을 가진다. | |
단일세라믹의 경우 사용이 제한되는 이유는? | 단일(monolithic) 세라믹은 높은 강성(stiffness), 강도, 고온안정성과 같은 매력적인 특성을 가지고 있으며 그 특성들은 생물의학, 전자, 자동차, 산업, 국방 및 우주 분야에 유용하게 사용되어지고 있다. 그러나 단일세라믹은 파괴인성이 취약한 경향이 있고, 따라서 기계적으로 신뢰성이 부족하며 전기전도성이 부족한 세라믹스는 사용이 제한된다. 이러한 특성의 개선을 위하여 섬유-세라믹복합체1)와 나노카본(그래핀, 탄소나노튜브)를 복합화한 구조세라믹스2)가개발되고 있다. | |
