Abstract
|
An efficient approach has been applied to assemble MgAl layered double hydroxide onto pristine carbon nanotubes using sodium dodecylsulfate. The assembling process and formation of such hybrid nanostructures were established using X-ray diffraction, Fourier transform infrared spectroscopy, field emission scanning electron microscopy and high-resolution transmission electron microscopy. Subsequently, the hybrid was used as nanofiller in the development of high-performance thermoplastic polyurethane/acrylonitrile butadiene rubber (1:1 w/w) blend nanocomposites. Measurements of mechanical and dynamic mechanical properties show that tensile strength, elongation at break and storage modulus improve significantly by 171%, 1.8 times and 241% in a blend with 0.50 wt% loading of hybrid filler. Thermogravimetric analysis shows that the thermal stability of the blend with 0.50 wt% hybrid filler compared to neat material is maximally improved by 20 °C determined at 50% weight loss. Differential scanning calorimetry shows the maximum enhancement in melting temperature (7 °C) and crystallization temperature (31 °C) due to significant nucleation efficiency of the filler, homogeneous dispersion and strong interfacial interaction between polymer matrix and filler. © 2015 Society of Chemical Industry
