Interface between the constituents plays an important role in the non-destructive detection of smart piezoelectric/piezomagnetic devices. The propagation of SH waves in nano-sized cylindrically multiferroic composites consisting of a piezoelectric layer and a piezomagnetic central cylinder is investigated, and the size-dependent dispersion relation with interface effect is derived. The general solutions...
Polyamide 11 (PA11) and its nanocomposites with different organoclay loadings were prepared by melt-compounding and subsequent pelletizing. The crystal phase transitions of PA11 and its clay nanocomposites were investigated by variable-temperature X-ray diffraction. It was found that the Brill transition of the nanocomposite was 20 K higher than that of the neat PA11 for both heating and cooling processes...
Poly(vinylidene fluoride) (PVDF) nanocomposites with different content of nanoclay were prepared by melt-intercalation method. The tribological behaviors of the PVDF/clay nanocomposites against 45 # carbon steel ring were evaluated on a block-on-ring type (M-2000) wear tester. Transmission electron microscopy (TEM) observation showed the dispersion of nanoclay in PVDF matrix. X-ray diffraction...
Nano-sized antimony trioxide (Sb 2 O 3 ) particles were modified by in-situ methyl methacrylate (MMA)/Sb 2 O 3 polymerization. Subsequently, these modified nanoparticles were compounded with poly(vinyl chloride) (PVC) to prepare PVC/Sb 2 O 3 nanocomposites. In-situ MMA/Sb 2 O 3 polymerization kinetics shows that nano-Sb 2 O ...
