dispersion of zinc oxide nanoparticles sem images

Dispersion Techniques of Nanoparticles

Fig 1 SEM micrographs of cryofractured surface of 20 wt% CNF/PEI nanocomposites obtained without (a) and with (b) ultrasonic treatment However with ultrasonic assisted it shows good dispersion of CNFs in PEI matrix There are two factors that influence the dispersion which are the screw rotation speed and ultrasonic amplitude [9] The effect of ultrasonic treatment time on
