3.2. Dispersion of SiO2 by ultrasonic
Dispersion of SiO2 by Ultrasonic in the UFP
Transmission electron micrographs (TEM) of
dispersion of SiO2 in UFP are shown in Fig. 1. As
the nano-surface interaction energy intensity, nanomaterials
are easy to aggregate to formation of
double ormultiple structures. It showed the particle
size of the aggregate structure was more than 500
n in the nano-UFP system. Transmission electron
micrographs (TEM) of dispersion by Ultrasonic for
10 min of SiO2 are shown in Fig 2. The multiple
structures were dispersed after 10min ultrasonic
dispersion. High surface energy of nano-particles
are interaction with e-cloud of UFP which with high
reactivity unsaturatedmolecular group, in that case
the surface activity of nanoparticles is reduced and
enhanced the stability of the nano-UFP system.
Therefore,UFPcan playa role in the nano-materials
