表示很无奈,我也在做这个,发文章不容易呀。。。
作者来自于duke大学等,文章主要讲述了纳米铜线外包裹Ni,来达到防止氧化的目的。在已经制得的铜线上包裹Ni。测试其光学和电学性能。最终得到的结果是放置较长时间后,纳米铜线的电阻率变化较小。
Synthesis of Oxidation-Resistant Cupronickel Nanowires for Transparent Conducting Nanowire Networks
ABSTRACT: Nanowires of copper can be coated from liquids to create flexible,
transparent conducting films that can potentially replace the dominant transparent
conductor, indium tin oxide, in displays, solar cells, organic light-emitting diodes,
and electrochromic windows. One issue with these nanowire films is that copper is
prone to oxidation. It was hypothesized that the resistance to oxidation could be
improved by coating copper nanowires with nickel. This work demonstrates a
method for synthesizing copper nanowires with nickel shells as well as the
properties of cupronickel nanowires in transparent conducting films. Time- and
temperature-dependent sheet resistance measurements indicate that the sheet
resistance of copper and silver nanowire films will double after 3 and 36 months at
room temperature, respectively. In contrast, the sheet resistance of cupronickel
nanowires containing 20 mol % nickel will double in about 400 years. Coating
copper nanowires to a ratio of 2:1 Cu:Ni gave them a neutral gray color, making
them more suitable for use in displays and electrochromic windows. These properties, and the fact that copper and nickel are
1000 times more abundant than indium or silver, make cupronickel nanowires a promising alternative for the sustainable,
efficient production of transparent conductors.
