Cs0.32WO3 Nanoparticles Applied for Thermal Insulation Dispersion

Some experts used transmission electron microscopy (TEM) to observe the microstructure and particle size distribution of Cs0.32WO3 nanoparticles for thermal insulation dispersion. The sample preparation method is to take a solid content of cesium tungsten bronze nano aqueous phase dispersion and mix with a certain amount of ethanol. After ultrasonic for 5 minutes, take 1-2 drops on a copper mesh covered with 300 mesh carbon film with a plastic dropper, tested after drying naturally.

The so-called TEM refers to the case where electron beams are projected on sample with small thickness to collide with atoms in the sample, thereby causing changes in the direction of the electron, and causing a scattering phenomenon related to the thickness and density of the sample, and therefore obtaining images of different samples. In general, ultrastructures of less than 0.2 microns can be observed under transmission electron microscopy, which is generally not visible under optical microscopy. At the same time, the size of individual particles can be directly measured, and the measurement range of the transmission electron microscope is 1μm-5μm.
