Abstract
Practical use of nanomaterials has drawn significant attention of researchers in the fields of nanoscience and technology. However, the control and processing of nanomaterials are still challenging especially for device applications.In this report, we prepared conducting thin films using silver nanowires (AgNW) and poly(acrylic acid) (PAA) via layerby- layer (LbL) assembly methods. The AgNW/PAA LbL assembled films exhibited typical adsorption behaviors with a linear increase in the UV-Vis absorbance at the maximum absorbed wavelength with increasing number of bilayers. We utilized X-ray photoelectron spectroscopy (XPS) to investigate the adsorption mechanism. The results revealed that both hydrogen bonding and coordination bonding were engaged in the assembly process. The sheet resistances of AgNW/PAA LbL assembled films were measured within the range of 4.2±0.6 Ω/sq to 14±2 Ω/sq, indicating their potential use as thin film conductors for the fabrication of opto-electronic devices.최근 나노물질을 실제 응용소자에 활용하고자 하는 시도가 많이 이루어지고 있다. 본 연구에서는 layer-bylayer( LbL) 자기조립 방법을 이용하여 은 나노와이어와 poly(acrylic acid)(PAA)를 전도성 박막으로 제조하였다. LbL 자기조립 과정을 관찰한 결과, 은 나노와이어와 PAA로 이루어진 이중층의 수가 증가함에 따라 최대 흡광도 값이선형적으로 증가하는 것을 알 수 있었다. 또한 X-ray photoelectron spectroscopy(XPS)를 통해 흡착 과정에는 수소결합과 배위결합 모두 관여한다는 것을 밝혀 내었다. 면저항 수치는 4.2±0.6 Ω/sq에서 14±2 Ω/sq 범위의 값을 가지는것으로 측정되었으며, 이는 본 연구에서 제안한 전도성 박막 제조방법이 광전자 소자의 전극제조에 활용될 수 있다는 가능성을 보여준다.
