已经开发出一种新的简便方法来合成银纳米线透明导电薄膜，该方法是通过还原作为前体制备的高长径比针状羧酸银，同时保持其形态。当以氧化银（I）和羧酸为起始原料时，通过超声辐照可简单地获得纳米线前体。在超声辐照之后进行微波辐照时，前体的长径比会增加。通过用肼气还原这些前体或用氩等离子体短时间辐照它们，可以很容易地获得银纳米线。所得纳米线的形态与已报道的典型纳米线不同。这些纳米线具有多孔形态，其中小纳米颗粒连接形成纳米珠线。由于其粗糙的形态，纳米珠线被认为可提高薄膜的透明度。这种新方法可以一步同时合成银纳米珠线并制备透明导电薄膜，从而可显著简化制造工艺。
A new facile process has been developed to synthesize silver nanowire transparent conductive films by reducing high‐aspect‐ratio, needle‐shaped silver carboxylates, prepared as the precursor, while retaining their morphology. Nanowire precursors are simply obtained by ultrasound irradiation when silver (I) oxide and carboxylic acids are used as starting materials. The aspect ratio of the precursors is increased when the ultrasound irradiation is followed by microwave irradiation. Silver nanowires can be easily obtained by reducing these precursors with hydrazine gas or irradiating them with Ar plasma for a short time. The morphology of the resulting nanowires is different from that of typical nanowires that have been reported. The nanowires have porous morphology, where small nanoparticles are connected to form nanobeadwire. The nanobeadwire is considered to increase the transparency of the film because of its rough morphology. This new method can synthesize silver nanobeadwires and fabricate the transparent conductive film simultaneously, in one‐step, so that it can significantly simplify manufacturing processes.
