Article history: Received March 26, 2013 Received in Revised form June 27, 2013 Accepted 28 June 2013 Available online 2 July 2013 A new durable antibacterial cotton fabric was successfully prepared by free-radical graft copolymerization of acrylic acid (AA) and itaconic acid (IA) onto a cotton fabric in an aqueous medium. Ammonium persulfate (APS) was used as the initiator in the presence of a...

polymer nanocomposites containing metals have been used in a wide range of applications due to their versatility, and tunable characteristics including physical, chemical, biological and mechanical properties. in this research work polystyrene-silver nanocomposite has been produced using polymerization of a w/o microemulsion system. styrene monomer was used as the oil or continues phase of the ...

Silver nanoparticles/MoS2 nanosheets (AgNPs/MoS2) nanocomposites were prepared by a hierarchical assembly procedure. The functional 0D/2D nanocomposite will be a good candidate in many application fields, such as catalysis, antibacterial activity, energy storage, chemical and biological sensing. The obtained nanocomposites were characterized using X-ray powder diffraction (XRD), transmission el...

silver-polyaniline (ag-pani) nanocomposites were prepared by in-situ oxidative polymerization of aniline monomer in sodium bis(2-ethylhexyl) sulfosuccinate (aot) solution as an emulsifier. the synthesis of silver-polyaniline nanocomposites was investigated as a function of several parameters such as aniline concentration, concentration of emulsifier (aot), concentration of oxidation agent and c...

Herein, we report for the first time, synthesis of silver nanoparticles-nitrogen doped graphene oxide-chitosan nanocomposite (SGC) from aqueous leaf extract Curcuma caesia plant and explored bacterial toxicology behavior SGC via agar disc diffusion method. is a medicinal herb utilized as reducing agent reduction silver-to-silver ions. Graphene oxide significant two-dimensional carbon nanomateri...

This research is reports the fungicidal properties of nano-size silver/chitosan nanoformulations (NFs) used as an agent for antifungal treatment of various seed borne plant pathogens. Fungal phytopathogens, especially seed borne disease causing species, Rhizoctonia solani, Aspergillus flavus, Alternaria alterneta were isolated form chickpea seeds. Differences were observed in the antifungal act...

Potentiometric sensor based on commercial pencil graphite electrodes coated with polyaniline (PAni) composite with Eosin Y (EY) termed as PGE/PAni-EY have been developed for potentiometric determination of silver ion. The electrode exhibited linear response with Nernstian slope of 57.6±0.8 mV per decade within the range of 1.0×10 to 1.0×10 M with limit of detection 6.5×10 M silver ion. Fast and...

tumor growth is characterized by uncontrolled cell division. for centuries, silver kushta powder, composed of nano and submicro silver particles, has been used in traditional iranian and pakistani medicine for the treatment of melanoma and breast cancer. we have found that these nanocomposite particles are similar to silver nanoparticles (agnps) in size and shape and that there are so differenc...

Sol-gel method has been used to fabricate nanocomposite films on glass substrates composed halloysite clay mineral and nanocrystalline TiO2. The methodology for the synthesis involves a simple chemistry method utilized nonionic surfactant molecule as pore directing agent along with the acetic acid-based solgel route with the absence of water molecules. The thermal treatment of composite films a...
