Physical and Mechanical Properties of Epoxy-Nanoparticulate Composite Adhesive

Abstract

The effect of type of nanoparticles on morphology, thermal and mechanical properties of epoxy-nanoparticulate composite adhesive produced via ultrasonic vibration process has been investigated. The morphology, thermal and mechanical properties of epoxy-nanoparticulate composite adhesive was measured with FESEM/AFM, DTA/TGA, and Hounsfield respectively. The FESEM/AFM images of the epoxy-nanoparticulate composite adhesive reveals significantly fine dispersion of nanoparticles. The incorporation TiO2 nanoparticles in epoxy adhesive results in improved glass transition temperature (Tg), thermal stability and tensile properties of the nanocomposite. But, the incorporation of comparatively finer size Al2O3 nanoparticles leads to decrease in the Tg, thermal stability and tensile properties of the nanocomposite.
