Abstract

Sample preparation is significantly important to the high-resolution transmission electron microscopy (HRTEM) characterization of nanomaterials. However, many general organic solvents can dissolve the necessary organic polymer support layer in TEM grid, which causes it difficult to obtain high-quality samples of oil-soluble nanomaterials. In this study, a new sample preparation method for oil-soluble nanomaterials has been developed by using the sublimable material as a transition layer. Experiments also show that there is no damage to TEM grids and high-quality HRTEM images can be obtained via this method. This approach paves the way to applicable HRTEM sample preparation of oil-soluble nanomaterials.

摘要

样品制备对于纳米材料的高分辨率透射电子显微镜（HRTEM）表征至关重要。然而，许多常见的有机溶剂会溶解TEM网格中必要的有机聚合物支撑层，这使得难以获得油溶性纳米材料的高质量样品。在本研究中，通过使用可升华材料作为过渡层，开发了一种用于油溶性纳米材料的新样品制备方法。实验还表明，该方法对TEM网格没有损害，并且可以通过该方法获得高质量的HRTEM图像。这种方法为油溶性纳米材料的适用HRTEM样品制备铺平了道路。
