Polymeric composite films with a high loading of nano-size silicates can hardly meet the increasingly stringent fireproof and smoke-free requirements during burning. Thus, it is desirable to prepare pure clay films that can block air, heat, and flame. Here we report an organic-free clay film capable of both flame- and heat-shielding. The film was prepared from the self-assembly of nanometer-thi...

BACKGROUND Nowadays significant attention is to nanocomposite compounds in water cleaning. In this article the synthesis and characterization of conductive polyaniline/clay (PANI/clay) as a hybrid nanocomposite with extended chain conformation and its application for water purification are presented. METHODS Clay samples were obtained from the central plain of Abhar region, Abhar, Zanjan Prov...

In order to study the influence of nano-clay on crack resistance cement-based materials, two kinds nano-metakaolin (NMK) and nano-attapulgite clay (NMA) were considered. The early cracking process mechanical properties cement mortar (NCM) was studied by using a plate knife-edge constraint test. Based fractal theory, distribution characteristics NCM surface cracks revealed, calculation method fo...

nano-encapsulated iron oxide in zirconium oxide-coated mica pigments are thermally stable,innocuous to human health, non-combustible, and they do not conduct electricity. they could beapplied in several industries such as thermoplastics, cosmetics, food packaging, children toys, paints,automobiles coating, security purposes, and banknotes. nowadays, they are highly desirable inceramic decoratio...

In this research, the corrosion effect has been investigated on high-cycle fatigue lifetime and fracture behavior for heat-treated aluminum-matrix nano-clay-composite piston aluminum alloys. For objective, after fabricating stir-casted nano-clay-composite, standard samples were machined rotary bending tests performed. To study effect, some specimens corroded in 0.00235 % H2SO4 solution 200 h th...

The usage of clay polymer composites has increased in the past few decades. Due to extensive availability, wide surface areas, and good adsorption efficiency polymers are gaining popularity amongst researchers remove range organic as well inorganic pollutants from effluents. This book chapter sheds light on characteristics, occurrence, types synthesis minerals used for preparing nano-clay compo...

nanocomposites based on vinyl ester resin (derakane 470-300) and nano clay (cloisite 30b) were prepared. the effect of clay content of 1, 3 and 5% (by weight) on the morphology, mechanical properties and water absorption of vinyl ester resin nanocomposites were studied. the nanocomposites were characterized  using  small-angle x-ray  scattering  (saxs),  feld  emission  scanning electron micros...

The dielectric dispersion behaviour of montmorillonite (MMT) clay nanoparticles colloidal suspension in poly(vinyl pyrrolidone)-ethylene glycol (PVP-EG) blends were investigated over the frequency range 20 Hz to 1 MHz at 30°C. The 0, 1, 2, 3, 5 and 10 wt% MMT clay concentration of the weight of total solute (MMT+PVP) were prepared in PVP-EG blends using EG as solvent. The complex relative diele...
