Abstract

Titania nanoparticle dispersion and its effect on thermal properties of epoxy-based nanocomposite were examined by producing it via ultrasonic vibration process. Atomic force microscope images of the epoxy/TiO₂ nanocomposite revealed a good dispersion of nanoparticle up to an optimum level of loading (10 wt%), which results in its improved glass transition temperature and thermal stability. But, a higher particle loading in epoxy reflects decrease in the glass transition temperature and thermal stability of the nanocomposite, which may be attributed to the significant increase in clustering of the nanoparticles.
