  • 탄소나노튜브의 전계방출 특성은 그 길이에 많은 영향을 받으며 길이가 균질 할수록 전계방출에 참여하는 탄소나노튜브의 수가 증가하여 전자방출의 균일도가 향상되고 수명도 증가할 것으로 기대되고 있다. 이 논문에서는 탄소나노튜브의 길이를 인위적으로 제어하여 균질하게 하기 위해 오존을 이용하여 길이가 긴 탄소나노튜브만 선택적으로 제거하는 방법을 사용하였다. 오존에 의해 처리한 시편은 전에 비해 높은 균일도를 나타내고 수명도 약 4배가량 크게 향상되었다.

  • Currently, nanotechnology is widely applied in various industrial fields and is rapidly emerging as a promising future technology. In food industries, nanotechnology is used to enhance food quality and safety. Numerous cutting-edge studies on the advantages of nanotechnology have been conducted in the fields of food processing, food ingredients and additives, food packaging, and food engineering for optimal health. The market for these areas of research has grown steadily, and is expected to continue to do so. Because of this, R&D for nanotechnology that can be used effectively in food industries is being performed by several companies, as well as in academic research institutions around the world. This review describes the recent global R&D trends that have been in progress for two key areas: food processing and food packaging.
