树脂包埋在透射电子显微镜测试中的应用

在环氧树脂包埋样品的过程中，部分样品易漂浮于树脂中而不易定位，因而影响了技术人员超薄切片的效率及样品在透射电子显微镜下的观察效果.对易漂浮于环氧树脂中的样品进行多次包埋定位，再通过修块、切片等步骤制备透射电子显微镜截面样品，特别适用于快速高效地制备纳米线、棒等截面样品.多次包埋方法操作简单、实用性强，经超薄切片后制备出的样品截面更清晰、更完整.

Application of Resin Embedding in Transmission Electron Microscopy

In the process of embedding samples in epoxy resin, some samples are easy to float in the resin and not easy to be in fixed position, thus affecting the efficiency of ultrathin sections and the observation effect of the samples under transmission electron microscope. It is especially suitable for the rapid and efficient preparation of nanowires, rods and other cross section samples by embedding and positioning the samples easily floating in epoxy resin for many times, and then preparing the cross section samples for transmission electron microscopy through the steps of block modification and section. The method of multiple embedding is simple and practical, and the sample section prepared by ultrathin section is clearer and more complete.
