【摘要】：纳米银线(Ag NWs)因其拥有独特的性能而被广泛的应用于光电子学器件、化工生产催化剂、生物纳米传感器、微纳机器人以及太阳能电池板等诸多领域。在透明导电薄膜(TCFs)的应用方面,纳米银线具有重要的研究意义。本文就Ag基TCFs的制备采用了两种不同的工艺方法。其一,首先合成AgNWs,再采用分层刮涂及热压的方法将纳米银线固定在基底(玻璃或PET)表层,形成Ag基TCFs。其二,首先采用静电纺丝技术将含供Ag生长的晶种纺到基材(玻璃或PET)表面,然后经过化学选择性生长的方法,在纺丝线表面长出纳米银,形成Ag基TCFs。众多研究者通过大量的研究发现,高长径比的AgNWs对提高透明导电薄膜的光电性能有着重要的意义。本文采用乙二醇还原法合成纳米银线,在以Ag NO3为主体剂提供Ag+,以乙二醇(EG)当作反应当中的溶剂以及还原剂,PVP作为为诱导剂,FeCl3·6H2O作为控制剂,在温度为120℃,Ar气氛围下成功合成了长度为50μm,直径为60 nm的形貌均匀的纳米银线(AgNW)。之后,采用分层刮涂的办法,在以温度为100℃,压力为50 kg,时间为30 min的热压作用下,成功的制备出了平均表面电阻38Ω/sq,平均可见光透过率为86%的Ag基TCFs。采用静电纺丝技术制备Ag基TCFs。创造性提出并研究在纺丝液中使用聚丙烯腈-聚苯乙烯的共聚物(SAN)以络合Ag+形成供Ag生长的晶种,再通过Ag的选择性生长反应形成Ag基TCFs。探究纺丝液中SAN的含量,以及收集静电纺丝时间对Ag基TCFs的光电性能的影响作用。经探究最优化条件,成功制备出表面电阻为20Ω/sq,可见光透过率为85.5%的Ag基透明导电薄膜。光打印法制备Ag基电路图形是基于传统技术以及现阶段喷墨打印技术的缺点而创造性提出的,其实现是基于分层涂布法制备Ag基透明导电薄膜以及紫外激光对光敏树脂的选择性固化作用的相结合。在现有条件下制备了最小线宽为0.25 mm,电阻率为21×10-5Ω·cm的导电图形。为日后制备出大规模集成电路提供了一种快速、方便、可行的方法。
[Abstract]:Nanocrystalline silver wire (Ag NWs) has been widely used in many fields such as optoelectronic devices, chemical catalysts, biological nanosensors, micro / nano robots and solar panels because of its unique properties. Nanocrystalline silver wire is of great significance in the application of transparent conductive film (TCFs). In this paper, two different methods for the preparation of Ag-based TCFs have been adopted. First, AgNWs were synthesized firstly, then silver nanowires were fixed on the surface of substrate (glass or PET) by stratified scraping and hot pressing to form Ag based TCFs. Secondly, silver nanoparticles were grown on the surface of the spinning wire by electrospinning technique, and then Ag based TCFs were formed by the chemical selective growth method on the surface of the substrate (glass or PET). Many researchers have found that AgNWs with high aspect ratio plays an important role in improving the optoelectronic properties of transparent conductive films. In this paper, silver nanowires were synthesized by ethylene glycol reduction, Ag was provided with Ag NO3 as main agent, ethylene glycol (EG) was used as solvent in the reaction and NO3 was used as inducer, FeCl 3 6H2O as control agent. Silver nanowires (AgNW). With a length of 50 渭 m and a diameter of 60 nm were successfully synthesized at 120 鈩，
