전기방사 기술이란? | 이러한 가운데 나노소재 분야에서는 나노기술의 전성기를 맞이하면서 나노재료의 제조법, 분석법, 그리고 나노소재의 융복합화에 관한 연구가 학계와 산업계 전반적으로 이루어지고 있다. 현재까지 다양한 구조와 물성을 갖춘 나노재료를 제조하는 방법이 소개되고 있는데 그 중에서도 전기방사 기술은 고분자, 세라믹, 복합물질 등 다양한 재료를 사용하여 연속적인 나노섬유를 제조할 수 있는 가장 일반적인 방법으로, 효율적이고, 비용이 저렴하며, 수 마이크로미터에서 수십 나노미터 정도의 극세섬유를 제조할 수 있는 기술이다(Bhattarai et al., 2005; Deitzel et al. | |
전기방사를 통해 제조된 섬유의 특징은? | , 2002). 전기방사를 통해 제조된 섬유는 매우 가는 직경을 가진 섬유로 단위 질량당 표면적이 매우 크고 유연하며 섬유 간 발생하는 미세공간이 많아서 타 소재와의 혼화가 가능하며 외부의 응력에 대한 분산이 큰 특징을 가지고 있다(Kim & Yeum, 2011; Sirin et al., 2013; Zhuo et al. | |
향나무 추출물 함유한 나노섬유의 전기방사 제조 후 구조적, 열적 특성과 항균특성의 결과는? | 향나무 추출물을 함유하는 폴리우레탄 복합 나노섬유를 전기방사를 통하여 제조한 후, 구조적, 열적 특성과 항균특성을 살펴본 결과, 다음과 같은 결론을 얻었다. 향나무 추출물을 함유하는 PU 나노섬유의 FT-IR 스펙트럼을 살펴본 결과, 향나무 추출물로 기인한 스펙트럼이 복합 나노섬유의 밴드에서 겹치는 것으로 나타났으며, 이로써 향나무 성분이 PU matrix 내에 균일하게 분산되었다는 것을 확인할 수 있었다. |
