초록
자기치유재료란 장기간 사용에 의한 기계적 충격에 의해 발생된 손상을 치료할 수 있는 능력을 발휘하도록 구조적, 화학적으로 개질시킨 스마트 재료의 하나이다. 사용에 손상이 일어난 부위를 본질적으로 치유할 수 있는 재료(고분자, 세라믹, 금속 등)를 사용함으로써 부품의 수명을 길게 할 수 있고, 장기간 사용에 의한 분해로 야기되는 효율의 감소를 막을 수 있으며, 재료의 파괴에 의한 비용지출을 막을 수 있어 여러 산업 공정의 생산단가를 낮출 수 있다. 최근 차량용 자기치유 페인트가 가능하다는 니싼의 발표 이후 재료의 자기치유능력에 대한 관심이 고조되고 있다. 본 총설에서는 앞서 발표한 자기치유 유 기재료에 이어 금속, 세라믹, 콘크리트 등 무기 재료의 자기치유 방법에 대해서 알아보고, 향후의 방향을 제시하고자 한다.
Self-healing materials are a class of smart materials that have the structurally incorporated ability to repair damage caused by mechanical usage over time. A material (polymers, ceramics, metals, etc.) that can intrinsically correct damage caused by normal usage could lower production costs of a number of different industrial processes through longer part lifetime, reduction of inefficiency over time caused by degradation, as well as prevent costs incurred by material failure. The recent announcement from Nissan on the commercial release of scratch healing paints for use on car bodies has gained public interest on such a wonderful property of materials. This article is a second part of healing materials dealing with inorganic engineering materials such as metals, ceramics, and concrete. The healing mechanisms developed for the inorganic materials are to be discussed with the future prospect.
