Preparation of SiC nanoparticles from plastic wastes

By a simple carbothermal reduction method, β-SiC nanoparticles with different sizes were prepared from plastic wastes, water bottles and disposable boxes. These particles were characterized by X-ray diffraction, transmission electron microscopy, dynamic light scattering and so on. The SiC nanoparticles synthesized from water bottles mainly have dimensions in the range of 5–20 nm, while the nanoparticles synthesized from disposable boxes mainly have dimensions ranging from 30 to 70 nm. Compared with the large SiC nanoparticles, the SiC nanoparticles with smaller size have better reinforcement effect in epoxy resin composites.
