Thermal and mechanical characterization of alumina modified multifunctional novolac epoxy nanocomposites

چکیده
The multifunctional novolac epoxy/Al 2 O 3 nanocomposites were fabricated by high-speed mechanical mixing of epoxy resin with varying concentration nano Al (0–5 wt%) particle size 13 nm for 30 min, followed curing triethylenetetramine (TETA) at 110°C 1 h and post-curing 80°C 5 h. nanocomposite samples characterized properties (viz., tensile strength, elongation-at-break, impact toughness, hardness shore D), thermal stability, fire retardancy. It was observed that the wt% nano-Al containing sample showed significant enhancement in D, retardancy compared to neat sample. Differential Scanning calorimetry (DSC) confirmed 3-D reaction between TETA nano-alumina modified samples. reactivity effect alumina towards investigated Fourier Transform Infrared (FTIR) spectroscopy. morphological studies Electron Microscopy (SEM) justify via dispersion nanoparticles.

Mechanical and Thermal Properties of Chemically Modified Epoxy Resin
Diglycidyl ether of bisphenol-A (DGEBA), having number average molecular weight (Mn) 375, was modified by incorporating the hydroxyl terminated polybutadiene (HTPB) based prepolymer using isophorone diisocyanate as a coupling agent. To increase the compatibility between the epoxy resin and HTPB part, polar groups were introduced in the later to achieve physical and chemical interactions between...

متن کاملThermal Stability of Imidazolium Modified Clay and Tgddm-based Epoxy Nanocomposites
High performance epoxy resin (tetra-glycidyl-4,4’diamino-diphenyl methane-TGDDM) is brittle and is sensitive to moisture absorption and thermooxidative effects. An approach to mitigate polymer sensitivity towards moisture and thermal effects is to add clay. The addition of clay to resin systems (e.g. diglycidyl ether bisphenol A-DGEBA) has often yielded an overall improvement in properties of t...
