Silver nanowires (AgNW) synthesized by a solvothermal method were incorporated into a polycarbonate matrix by a solution mixing procedure. Films with a thickness around 18 μm were obtained, showing a good distribution of the wires within the polymer matrix. The thermal stability of the polymer matrix increased significantly, with the main decomposition peak shifting up to 74 ° C for an AgNW loading of 4.35 wt%. The percolation threshold was obtained at very low AgNW content (0.04 wt%), and the composite electrical conductivity at the maximum loading (4.35 wt%) was 41.3 Ω cm. Excellent transparency was obtained at the percolation threshold, with negligible reduction in the transmittance of the polymer matrix (from 88.2 to 87.6% at 0.04 wt% loading of AgNW). In addition, the polymer matrix protected the silver nanowires from oxidation, as demonstrated by the XPS analysis.
采用溶剂热法合成的银纳米线（AgNW）通过溶液混合工艺掺入聚碳酸酯基质中。得到厚度约为 18 μm 的薄膜，其中纳米线在聚合物基质中具有良好的分布。聚合物基质的热稳定性显著提高，当 AgNW 负载量为 4.35wt%时，主要分解峰向上移动了 74°C。在非常低的 AgNW 含量（0.04wt%）下即可达到渗流阈值，在最大负载量（4.35wt%）时复合材料的电导率为 41.3Ωcm。在渗流阈值时获得了极好的透明度，聚合物基质的透光率几乎没有降低（在 0.04wt%AgNW 负载量时，透光率从 88.2%下降到 87.6%）。此外，XPS 分析表明，聚合物基质保护了银纳米线免受氧化。
