Controlling the Distribution and Agglomeration of Silver Nanoparticles on Polyamide Nanofibers

聚合物纳米纤维膜通常用于智能纺织品和服装，液体或水过滤，化学过程，空气过滤以及生物医学载体（例如生物医学载体）中。

Within specialized applications, fibers may be treated with antibacterial materials in order to provide additional benefits.

纳米胶体颗粒yabo214

纳米层颗粒最近已被证明具yabo214有抗真菌，抗菌，抗炎和抗病毒特性。这使它们特别适合改善聚合物纳米纤维膜中使用的纤维。

在此生产过程中，最常见的挑战包括有效控制银颗粒在纤维表面的分布，以及控制银颗粒本身的聚集。yabo214

Scanning Electron Microscope: TESCAN VEGA3

扫描电子显微镜（SEM）为该控制问题提供了一种这样的解决方案，因为反向散射的电子检测是“物质敏感的”。亚博网站下载与原子数较低的材料相比，原子数较高的材料将显得更明亮，这意味着在实践中，银颗粒看起来比纤维更明亮。yabo214

在下面介绍的SEM观察中，可以看到银的单个颗粒及其在纤维表面上的分布。yabo214

这一点尤其重要，如果可以有效地评估有关银颗粒的大小和团聚的信息，则可以相应地完善生产过程，从而改善。yabo214

These observations were performed with theTESCAN VEGA3 SEM在Pardam Nanotechnology Company提供的样本上。使用BSE检测器以10 kV获取这些SEM图像。
