“…The bands at 2920 and 2855 cm -1 are generally assigned to stretching vibration modes (v) of CH 3 in (OC 2 H 5 ) and CH 2 in (CH = CH 2 ) [48], respectively, while the band at 2920 cm -1 is also attributed to stretching vibration modes of CH 3 in (OCH 3 ) [49,50]. However, these two bands at 2920 and 2855 cm -1 are also faintly observable in the spectrum of pristine Al 2 Mo 3 O 12 and are attributed to [51].…”

Recently, polymer composites reinforced with low fractions of thermomiotic nanoceramics have triggered a lot of research. The efforts have been focused on achieving considerable reduction of the coefficient of thermal expansion (CTE) of polymeric materials without deterioration of other physical properties. In this context, polyethylene (PE) composites reinforced with different loads of Al 2 Mo 3 O 12 nanofillers (0.5-4 mass %) were fabricated by micro-compounding. To enhance the interfacial interaction between the two components, chemical functionalization of Al 2 Mo 3 O 12 was performed with vinyltrimethoxysilane (VTMS) prior to micro-compounding. Infrared spectroscopy and thermogravimetry demonstrated the successful grafting of VTMS on the Al 2 Mo 3 O 12 surface. The composites showed strongly decreased CTEs, up to 46 % reduction for loadings of 4 mass % compared with neat PE, suggesting intimate filler-matrix interactions. The variation of CTEs of the composites in terms of the filler fraction was successfully described by Turner's model allowing calculation of the bulk modulus of monoclinic Al 2 Mo 3 O 12 (13.6 ± 2.6 GPa), in agreement with the value obtained by an ultrasonic method. The thermal stability of the composites was improved, although the addition of functionalized fillers decreased the degree of crystallinity of the PE to a small extent. The Young's modulus and yield strength of the composites increased from 6.6 to 19.1 % and 4.0-6.0 %, respectively, supporting the existence of strong filler-matrix interactions, contributing to an efficient load transfer.

Polyethylene/TiO 2 membranes were fabricated via thermally induced phase separation (TIPS) method. A set of characterization tests including FE-SEM, EDX, XRD, DSC, TGA, DMA, mechanical test and relative pure water flux for characterization of membranes were carried out to investigate the effect of TiO 2 nanoparticles on membrane properties. The results of EDX, XRD and TGA analyses confirmed the presence of TiO 2 nanoparticles in the polymer matrix. The results of DSC analysis revealed that the melting point as well as the crystallinity of the membranes increased slightly with increasing TiO 2 content. However, the glass transition temperature of the membranes was not affected by the presence of particles. Addition of nanoparticles also increased storage modulus, loss modulus and tensile strength at break of the membranes due to the stiffness improvement effect of inorganic TiO 2 . Finally, it was observed that incorporation of the nanoparticles improved pure water flux of the membranes.

“…It is well known that the addition of nanosized materials into the polymer alters its mechanical properties [32]. The influence of nanoparticles (Fe 2 O 3, ZnO and TiO 2 ) on the mechanical properties of PS was investigated by tensile strength, the elongation at break (Eb) and Young's modules of the film.…”

REPARAT ION of nano metal oxides (Fe2O3, ZnO and T iO2) and nano …… sphere polystyrene (PS) has been done in micellar solution. Nanocomposite films have been prepared by doping nano polystyrene with different ratios of nano metal oxide ranged from 0.25 up to 3 wt%. T hese nanocomposites were characterized using transmission electron microscopy (T EM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT IR).Thermo gravimetric analysis (T GA) and mechanical properties have also been investigated. By comparison with the values obtained for the PS, it was observed that the thermal stability is higher for the nanocompoistes and increases with increasing the nano metal oxides concentration in these samples. T he results indicate that the tensile strength, elongation at break and Young's modulus of all the nanocomposites enhanced with the addition of metal oxides nanoparticles compared with the pure PS.
