Abstract:
The effect of addition of silica nanoparticles on thermal properties of acrylamide-styrene-maleic anhydride ‎terpolymer fabricated by in situ inverse micro emulsion polymerization method was investigated. For this ‎purpose, the terpolymer containing 1 wt. % weight percent silica nanoparticles was compared. First, by using ‎Fourier Transform Infrared Spectroscopy (FT-IR), the formation of terpolymer and the incorporation of silica ‎nanoparticles into the structure of the terpolymer were investigated. Then the morphology and particle size of ‎silica nanoparticles were studied using field emission scanning electron microscopic (FE-SEM). The thermal ‎properties including glass transition temperature (Tg), and thermal stability were tested by differential scanning ‎calorimetry (DSC) and thermogravimetric analysis (TGA). The result showed that the incorporation of silica ‎nanoparticle noticeably enhanced the thermal features of the terpolymer. The Tg of the nanocomposite shifted to ‎higher temperatures and the thermal degradation started at higher temperatures. Such results can be due to the ‎incorporation of nanoparticles on the polymer chains during the terpolymerization.‎
