“…Some physical properties of SiO 2 nanoparticles are explored by some scholars according to MD. Liu et al [9] studied the effects of water molecular absorption in the epoxy resin on the interfacial bonding of SiO 2 nanoparticles. The results showed that the strong interfacial adhesion of hydrophilic SiO 2 nanoparticles in anion surfactant of ethylene oxide due to van der Waals, electrostatic, and hydrogen bond interactions [10].…”

The dispersion characteristic of nanoparticles is of more interest in some engineering applications, including polymer filling, foam stability, chemical catalysis, and materials surface package. In this paper, the surface modification of SiO 2 nanoparticles was carried out based on molecular dynamics simulation. The characteristics of aggregation and diffusion of SiO 2 nanoparticles were explained by the radial distribution function (RDF), concentration profile, length distribution, mean squared displacement (MSD), and microscopic testing (MT). The results showed that the orbital provided by the three types of atoms (H, O, and Si) corresponding to the different bandwidths caused the energy alternation of state density. According to the results of RDF, the H O bond energy mainly provided by the water molecules showed the maximum bond energy with 463 kJ/mol. The results indicated that the bonds breakage and formation were accompanied by changes in total energy, kinetic energy, non-bond energy, and potential energy. After the modification of SiO 2 nanoparticles, the concentration profile of the water molecules decreased first at 1-8.5 Å and then increased at 8.5-17.2 Å, but the length distribution climbed to 15.7 at 0.975 Å.When the temperature reached 398 K, the peak value of the length distribution declined to 13.6 Å and the relative concentration profile of water molecules fluctuated around 1.0. With the increase of salinity, the peak value of length distribution reached 15.7 at 0.975 Å, but the concentration profile of water molecules at 3.1-9 Å decreased quickly and then gradually increased. The results of MSD and MT about water molecules presented the largest diffusion coefficient appeared at 398 K and had the best dispersion effect owing to the average kinetic energy among the molecules. Conversely, the diffusion coefficient decreased with the incremental solution salinity because the inhabitation of sodium for the motion of water molecules resulted in the ion bridging and hydrogen bonding.
