Synthetic studies of nanocomposites containing gold nanoparticles attached onto wood or bacterial cellulosic fibres have been performed in situ in the presence of the fibres or by polyelectrolyte-assisted deposition. The optical properties of the final nanocomposites could be tailored not only by the starting Au nanoparticles characteristics but also by the preparative method associated to the type of cellulosic fibres used as the substrate. Thus, gold nanoparticles assembled or generated in situ within cellulosic fibres, are excellent components for long term optical and chemically stable nanocomposites, which appear particularly interesting for security paper applications.
已通过在纤维存在的情况下原位进行，或通过聚电解质辅助沉积，对含有附着在木材或细菌纤维素纤维上的金纳米颗粒的纳米复合材料进行了合成研究。最终纳米复合材料的光学性质不仅可以通过起始金纳米颗粒的特性来调整，还可以通过与用作基材的纤维素纤维类型相关的制备方法来调整。因此，在纤维素纤维中原位组装或生成的金纳米颗粒是用于长期光学和化学稳定的纳米复合材料的优异组分，这对于防伪纸应用显得特别有趣。
