纳米材料分析

来自微小颗粒的重大发现

纳米材料被定义为至少有一维的尺寸经测量为 100 纳米或更小的材料,鉴于 1 纳米是 1 毫米的百万分之一,所以必须使用特殊的工具才能在该级别上研究材料。

在纳米技术中,研究人员检测混合了有机化合物和无机化合物的材料,例如 OLED。适用于纳米材料分析的两大有力工具是拉曼光谱法和 X 射线光电子能谱,这两者都能探测无机和有机材料层。

XPS 是薄膜和超薄薄膜分析的主要技术。它对于表征纳米颗粒的单层涂层十分有用。通过加入团簇离子源溅射,它还可以用于表征聚合材料和金属材料层。

拉曼光谱法是表征材料空间分布和相位均匀性以及晶体结构和分子取向的有用工具。它特别适用于诸如石墨烯之类的碳材料的分析。

双螺杆挤出机提供了一种混合、共混和加工粘性材料的完善方法。设备具有高度灵活性,可针对诸如小规模实验室挤出机的特殊任务进行轻松定制,在分析珍贵或昂贵的成分时减少废物的排放。

发现石墨烯潜在的用途仅仅是开始

石墨烯,一种以蜂巢形式排列的碳原子薄单层,是近六年来才被分离和探寻到的一种新型材料。这种神奇新型材料的很多潜在价值仍未被开发出来。

石墨烯:

  • 比钢铁更坚固
  • 几乎透明
  • 极好的导热体和导电体
  • 极薄,被认为是二维结构
石墨烯的潜在用途

在创建新的石墨烯器件的所有步骤中均要求良好的材料表征,从引导初始石墨烯合成、转移至所需的基底,到成品器件的化学改性和分析。采用拉曼光谱法和 X 射线光电子能谱 (XPS) 的多技术方法,能够应对这些步骤中所要面临的挑战。

拉曼光谱法和 XPS 可以作为以石墨烯为基础的样品全面表征的互补技术。拉曼光谱法提供分子结构、形态学和薄膜质量、应力以及层厚的相关信息。XPS 可提供化学定量分析、杂质鉴别、层厚度以及深度组成变化的相关信息。
