在这里，我们描述了在银纳米线存在下，氨基端低甘氨酸肽不寻常的自组装成扩展的二维薄片。通过x射线光电子能谱的电荷转移相互作用证明，所得到的析聚物薄片对纳米线具有很强的亲和力。我们表明，金属肽杂交体的扩展组装提供了额外的增强功能；例如，结构聚合物片在本质上是疏水性的，当暴露在大气条件下时，它可以作为保护层防止纳米线的氧化和降解。此外，对于银纳米线渗透网络，肽的存在通过机械挤压网络中的导线结显着增加了总体导电性。肽-金属界面可以通过pH刺激来控制，因此可能为银纳米线组件用于从抗菌涂层到生物传感器的透明电极提供新的方向。
Here, we describe the unusual self-assembly of amine-terminated oligoglycine peptides into extended two-dimensional sheets in the presence of silver nanowires. The resulting tectomer sheets are shown to have a strong affinity for the nanowires through a charge-transfer interaction as evidenced by X-ray photoelectron spectroscopy. We show that extended assemblies of metal–peptide hybrids offer additional augmentative functionalities; for instance, the tectomer sheets are hydrophobic in nature and act as a protective layer preventing oxidation and degradation of the nanowires when exposed to atmospheric conditions. Moreover, for silver nanowire percolating networks the presence of the peptide markedly increases the overall electrical conductivity through mechanical squeezing of wire–wire junctions in the network. The peptide–metal interface can be controlled by pH stimulus thus potentially offering new directions where silver nanowire assemblies are used for transparent electrodes ranging from antimicrobial coatings to biosensors.
