AAO 템플레이트을 이용한 균일한 공액고분자 나노와이어
Fabrication and Characterization of Conjugated Polymer Nanowires with Uniformed Size
본 논문에서는 유기전자소자의 반도체 물질로 많이 사용되는 poly(9,9-dioctylflurorene) (PFO), poly(9,9-dioctylfluoreneco-benthiadiazole) (F8BT), (regioregular poly(3-hexylthiophene) (P3HT)를 기반으로 하는 균일한 크기와 특성을 가지는 고분자 나노와이어를 AAO 템플레이트를 이용하여 대량으로 제작하였다. 제작된 나노와이어는 결점이 없이 깨끗한 표면을 보였으며, 약 250~300 nm의 지름과 ~30 μm의 일정한 길이를 가지고 있었다. 나노와이어들은 스프레이 분사 방법을 통하여 유리 기판 위에 균일하게 분사할 수 있었으며, PFO와 F8BT 나노와이어의 경우 UV 빛의 조사하에 각각 나노와이어의 전체에 걸쳐서 왜곡없이 밝은 yellow와 blue luminescence를 보였다.
Here, we reported mass-produced organic nanowires with uniform sizes based on poly(9,9-dioctylflurorene) (PFO), poly(9,9-dioctylfluorene-co-benzothiadiazole) (F8BT), (regioregular poly(3-hexylthiophene) (P3HT) which are well known as organic semiconductors for opto/electronics applications, using a melt-assisted wetting method with anodic alumina membrane. The conjugated polymer nanowires showed uniformed diameters (D=250~300 nm) and lengths (L
=~30 μm) with defect free smooth surface regardless of a kinds of semiconductors. In addition, the nanowires were uniformly deposited onto glass substrates by spray-coating method. Under the UV light irradiation, PFO and F8BT nanowires showed blue and yellow emissions, respectively.
