In this paper, we describe a novel method of silver nanowire (AgNW) synthesis. Silver nanoparticles (AgNPs) were synthesized under ambient conditions by a chitosan/chitin-based method. These crystalline AgNPs then served as seeds for the solid-state formation of AgNWs within a drop-cast chitosan/chitin thin film. To the best of our knowledge, this is the first report of AgNW growth on a bio-polymer thin film. Chemical analysis demonstrated that AgNPs and AgNWs produced by this synthetic process have distinct interactions with polysaccharide polymers, and unlike AgNWs produced by other methods, the AgNWs formed in the chitin/chitosan matrix display an irregular twisted morphology. The flexible AgNW/chitosan nanocomposite material is conductive, and we incorporate this new material into a peroxide sensor to demonstrate of its potential applications in chemical sensing devices.
在本文中，我们描述了一种合成银纳米线（AgNW）的新方法。通过基于壳聚糖/几丁质的方法在环境条件下合成了银纳米颗粒（AgNP）。然后，这些结晶AgNP作为种子，用于在滴铸的壳聚糖/几丁质薄膜内固态形成AgNW。据我们所知，这是关于在生物聚合物薄膜上生长AgNW的首次报道。化学分析表明，通过该合成过程产生的AgNP和AgNW与多糖聚合物具有不同的相互作用，并且与其他方法产生的AgNW不同，在几丁质/壳聚糖基质中形成的AgNW呈现不规则的扭曲形态。柔性AgNW/壳聚糖纳米复合材料具有导电性，我们将这种新材料整合到过氧化物传感器中，以证明其在化学传感装置中的潜在应用。
