  This review reports recent advances in the field of polymerlayered silicate nano composites. Thesematerials have attracted both academic and industrial attention because they exhibit dramaticimprovement in properties at very low filler contents. Herein, the structure, preparation andproperties of polymerlayered silicate nanocomposites are discussed in general, and finally the effectof clay nanoparticles on optical and Rheological properties of polymeric products were alsodiscussed. پرونده مقاله

  AbstractThermal and antimicrobial properties of hybrid synthesized compounds were evaluated in the present study. Hybrid structures were synthesized via two main organic and inorganic components, namely: 2-Mercaptobenzothiazole (MBT) and sodium Montmorillonite clay (Na+-MMT). The synthesis process took place in a direct reaction, intercalation; and the resulting material was characterized. Results of scanning electron microscope (SEM), Energy dispersive X-ray spectroscopy (EDS), transmission electron microscope (TEM), small-angle X-ray scattering (SAXS) and Fourier transform infrared spectroscopy (FTIR) confirmed MBT penetration of particles into the inner space of the clay layers and interaction between the two organic and inorganic phases. Also, thermal properties of the resulting compounds were evaluated by thermo gravimetric analysis (TGA) and differential thermal gravimetric (DTG). It was found that while MBT sample had relatively low degradation temperature (about 250°C), the MBT-modified clay compound showed superior thermal stability, and in high temperatures, less weight loss as compared to MBT. Antimicrobial properties of the hybrid nanocompound against five types of bacteria, two types of fungus and one type of yeast were examined using well diffusion agar method and minimum inhibitory concentration (MIC). The diameter of inhibition zone was measured and their antimicrobial potential was compared with two common antibiotics: gentamicin and rifampin. The concentration of about 1000 μg/mL of MBT-MMT showed antibacterial performance equal to 250 μg/mL of rifampin. Also, 1000 μg/mL of this material was required to inhibit the growth for important bacteria. پرونده مقاله
