Abstract

$V_2O_5$ nanowire / polyvinyl alcohol (PVA) polymer composite fibers were fabricated by a new simple method. The reaction of PVA and acetone facilitates the formation of the polymer membrane which can be used to make the fiber. Composite fiber is percolative in the conductance because of the low percolation threshold in $V_2O_5$ nanowire networks. The fiber composite can be applied to the electromagnetic shielding originating from the conductive nature.

$V_2O_5$ 나노선/폴리비닐 알코올(PVA) 고분자 복합체를 나일론 제조법을 응용하여 제작하였고 전기적 특성을 연구하였다. PVA가 아세톤, 에탄올, 메탄올 등의 벤젠기와 반응하여 얇은 막을 형성하는 것을 이용하여 나일론 섬유 제작방법과 유사하게 실타래를 감아올려 나노선 섬유가 섞인 폴리머 섬유를 만들었다. 폴리머-나노선 복합체는 내부에서 전도성이 있는 $V_2O_5$나노선 다발이 네트워크를 형성하기 때문에 전자기장을 차폐할 수 있는 고분자 섬유 등에 적용할 수 있다.
