Understanding the effect of adding nanoclays into epoxies

摘要: Different preparation methods and formulations of epoxy nanocomposites have been examined. The effects each parameter, such as different types clay, curing agent, processing conditions (temperature, time, speed), on dispersion the clay particles were evaluated using means, field emission gun scanning electron microscopy (FEGSEM), X-ray diffraction (XRD), transmission (TEM), viscometer. Curing behavior was studied by differential calorimetry (DSC) Fourier transform infrared spectroscopy (FTIR). Thermal properties thermogravimetric analysis (TGA), limiting oxygen index (LOI). Dynamic mechanical dynamic (DMA). Tensile, flexural, compression, impact, surface hardness fracture toughness also A new method to disperse organoclay into without solvent, high speed mixing (TS), is proposed. results obtained from this study provide a good understanding relationship between formulation, performance. Significant improvement in stiffness storage modulus observed formulated with better TS. However, extent nanocomposites' performance depends type agent. In addition, great final nanocomposites.
