Abstract:
In nanocomposite materials fabrication, nanopowders are commonly used to obtain the desired properties. However, the drawbacks of nanopowders are agglomeration and poor handling ability. To overcome these issues, one solution is to fabricate composite granules using electrostatic integrated granulation of aqueous nanopowder suspension. By adjusting the surface charge potential of the nanopowders, electrostatic integration during the granulation process enabled the fabrication of monodispersed spherical composite granules, exhibiting good homogeneity of raw nanoparticles and improved handling ability. In this study, the parameters for composite granules formation using electrostatic integrated assembly method were investigated. From the results obtained, a process map, which enables the prediction of the granule’s formation is also proposed.
