Clay-based nanocomposites have been studied for several decades, mainly focusing on clay-polymer nanocomposites. Here, we report on a simple wet chemical method to synthesize clay-APTES-Au (CAAu) nanocomposites, where 3-aminopropyltriethoxysilane (APTES) acts as the linkage. The silane terminal of APTES formed bonds with the clay surface, while the other -NH(2) terminal bonds to gold nanopartic...

Many attempts have been made to fabricate various types of inorganic nanoparticle-filled polymers (filler/polymer nanocomposites) by a mechanical or chemical approach. However, these approaches require modification of the nanofiller surfaces and/or complicated polymerization reactions, making them unsuitable for industrial-scale production of the nanocomposites. The author and coworkers have pr...

This paper reports the synthesis of CeO2/ZrO2 nanocomposite by wet chemical method using cationic surfactant (CTAB). The properties of the obtained nanocomposites were analysed by X-ray diffraction (XRD), Fourier transform infrared (FTIR), scanning electron microscoy (SEM), transmission electron microscopy (TEM), UV-Diffuse Reflectance Spectroscopy (UV-DRS) and photoluminescence (PL) spectrosco...

in this work firstly fe3o4 nanoparticles were synthesized via a sono-chemical method. at the second step magnesium hydroxide shell was synthesized on the magnetite-core under ultrasonic waves. for preparation fe3o4-mgo the product was calcinated at 400 ºc for 2h. properties of the product were examined by x-ray diffraction pattern (xrd), scanning electron microscope (sem) and fourier transform ...

Multifunctional core-shell nanocomposites with a magnetic core and a silica shell doped with lanthanide chelate have been prepared by a simple method. First, citric acid-modified magnetite nanoparticles were synthesized by a chemical coprecipitation method. Then the magnetite nanoparticles were coated with silica shells doped with terbium (Tb(3+)) complex by a modified Stöber method based on hy...

Here, we report a simple, cheap, and rapid synthesis method combined with physical and chemical routes for porous structured metal-based carbon nanocomposites, which can be applicable to anode materials for high performance Li-ion batteries.

We report on synthesis of two highly disperse nanoparticles viz. Fe2O3 & f-Fe2O3 using chemical reduction method. Reaction was initiated to mix solution A (i.e. Fecl3 6H2o) into solution B (i.e. Fecl24H2o) together under the presence of ammonium to develop nanoparticles. Mechanical properties of above mentioned nanoparticles filled with polyester polymer nanocomposites were fabricated to assess...

Of late, graphene has occupied the attention of almost all researchers working globally in the area of materials science. Graphene nanocomposites are the latest additions to the wonder applications of graphene. One of the promising applications of the graphene-oxide nanocomposites is chemical sensing which is useful for monitoring the toxicity, inflammability, and explosive nature of chemicals....
