ResonantAcoustic® Mixing Blending Nano and Micron Sized Particles Background Resodyn Acoustic Mixers has developed a novel mixer product line that uses low-frequency, highintensity sound energy for mixing. The mixer technology, trademarked under the name ResonantAcoustic®, is applicable to a broad range of mixing classes that include gases, liquids, solids and powders systems. Highlighted here is just one of many applications: Blending Nanoparticles with Micron Sized Particles. Starting Materials Nanoparticle Blending A micron-sized polymer powder was blended with a nano-sized oxide powder in a dry state. The images on the right, taken with a scanning electron microscope, show the starting materials in the first column and the mixed powders in the second. The Micron-sized polymer powder average diameters of the shown at 500X magnification. polymer particles and the oxide agglomerates were 40 microns and 30 microns respectively, whereas the individual nanoparticles had an average diameter of 50 nm. After only ten minutes of mixing the two materials were thoroughly blended and the surface of the Iron oxide nanopowder agglompolymer powder was uniformly erates at 500X magnification and coated with the nano-sized inset at 10 000X magnification. oxide.
