Some of the important thermo-mechanical characteristics of Boehmite-polyamide-6 nanocomposites are presented. Two different types of Boehmite (γ-AlOOH) are investigated, which are unmodified and surface-modified using a titanate-coupling agent. Since use-temperature range is one of the most important parameters for engineering polymers, heat distortion temperature (HDT) and glass transition temperature...
Nematic phase behavior of titanate-treated Boehmite rods in a polyamide-6 matrix is reported. Optical polarization microscopy (OPM) and wide-angle X-ray scattering (WAXS) performed during heating and cooling cycles, are used to provide information on the level of orientation of Boehmite rods and polyamide-6 crystallites. The nematic orientation of Boehmite is clearly indicated by the permanent birefringence...
This work reports the use of titanate-modified Boehmite particles in making polyamide-6 nanocomposites complementary to our previous work, which discussed the use of unmodified Boehmite. A new method for the surface modification of Boehmite has been applied. The characterization methods include transmission electron microscopy (TEM), atomic absorption spectroscopy (AAS), thermogravimetric analysis...
Colloidal boehmite particles have been included into a polyamide-6 matrix by in situ polymerization. The particles have been used without any surface modification. Characterization of the nanocomposites has been carried out using transmission electron microscopy (TEM), dynamical mechanical analysis (DMA) and differential scanning calorimetry (DSC). TEM images indicate that the particles have been...
