This technology is a process for modifying the surface chemistry of commercially available silicon dioxide (SiO2) nanoparticles without causing agglomeration, which can be utilized for the fabrication of high-performance nanocomposite materials.
The addition of nanoparticles to bulk polymers to upgrade their mechanical, optical, and electrical properties is desirable for a variety of applications ranging from consumer electronics to automotive tires. The performance of these nanocomposite materials is highly dependent on the dispersion of the nanoparticles within the bulk material to achieve a high surface area-to-volume ratio. However, controlling the dispersion of nanoparticles in polymers is a major challenge, as nearly all nanoparticles agglomerate into larger structures when added to polymers, compromising the mechanical properties.
The method modifies the particle surface with hydrophobic trimethylsilyl groups to enable dispersion in organic solvents. Mixture with the desired polymer and evaporation of the solvent results in a polymer nanocomposite with highly disperse nanoparticles, leading to improved mechanical properties. This technology can be utilized for the fabrication of high-performance nanocomposite materials for a wide range of industries.
