About the Journal :
Experimental and Theoretical NANOTECHNOLOGY (ETN) abbreviated as Exp. Theo. NANOTECHNOLOGY is a multidisciplinary peer-reviewed and open access journal. It includes specialized research papers, short communications, reviews and selected conference papers in special issues on the characterization, synthesis, processing, structure and properties of different principles and applications of nanotechnology with focus on advantageous achievements and applications for the specialists in engineering, chemistry, physics, materials science and medicine. ETN covers and publishes all aspects of fundamental and applied researches of experimental and theoretical nanoscale technology dealing with materials synthesis, processing, nanofabrication, nanoprobes, spectroscopy, properties, biological systems, nanostructures, nanoelectronics, nano-optics, nano-mechanics, nanodevices, nanobiotechnology, nanomedicine, nanotoxicology within the scope of the journal. ETN aims to acquire the recent and outstanding researches for the benefit of the human being.
Two main groups of samples were prepared. The first one was poly (vinyl chloride) (PVC) loaded with different concentrations of as received single walled carbon nanotubes (SWCNTs), while the second was PVC loaded with different concentrations of single walled carbon nanotubes functionalized with three-hydroxy-2- -HNA) at a concentration of 0.04wt%. The dc electrical conductivity and its temperature dependence of theses samples were investigated. Also, the tensile, rheological as well as the dynamical mechanical properties of -HNA was found to enhance the dc electrical conductivity, elastic modulus, tensile strength, complex viscosity, storage modulus and the glass transition temperature. The dc electrical conductivity had a percolation behavior with a percolation threshold concentration of 0.35 and 0.22wt% of un-functionalized and functionalized CNTs, respectively. The enhancement of the electrical and mechanical parameters with functionalized SWCNTs indicated well dispersion of CNTs due to formation of side functional groups on their sides.
