Abstract
Description
도 2a는 키토산/CNT 하이브리드 필름 사진이다.
도 2b는 키토산으로 코팅된 탄소나노튜브 원통형 복합체들이 수소결합을 통해 서로 네트워크를 형성하고 있는 SEM 이미지이다. 이때 모든 가닥 가닥 사이에서 나노 단위의 크기를 갖는 수많은 기공들이 존재함을 확인할 수 있다.
도 3은 탄소나노튜브와 키토산이 결합된 탄소나노튜브-버키페이퍼를 변형(strain)시킬 때의 응력(stress)의 변화를 나타낸다.
도 4는 키토산-탄소나노튜브-버키페이퍼 (chit-CNT 50) 샘플 중 chit-CNT 50의 온도 변화에 따른 중량 변화를 나타내는 열중량분석기(TGA)의 데이터이다.
도 5는 키토산-탄소나노튜브-버키페이퍼 샘플 중 chit-CNT 50의 FT-IR 스펙트럼이다.
