Activation behaviour and dielectric relaxation in polyvinyl alcohol and multiwall carbon nanotube composite films
The dc and ac electrical transport property of Polyvinyl Alcohol-Multiwall Carbon Nanotubes (PVA-MWNT) composites has been investigated within a temperature range 77≤T≤300K and in the frequency range 20Hz to 1MHz. The temperature variation of dc conductivity gives the presence of two different activation energies. The dielectric properties of the samples have been explained in terms of electric...
متن کاملDielectric relaxation of water inside a single-walled carbon nanotube
We report a molecular dynamics study of anisotropic dynamics and dielectric properties of water confined inside a single-walled carbon nanotube (SWNT) at room temperature. The model includes dynamics of an SWNT described by a realistic potential function. A comparison with simulations assuming a rigid nanotube demonstrates that the popular assumption severely overestimates the dielectric consta...
متن کاملEnzyme-carbon nanotube conjugates in room-temperature ionic liquids.
Room-temperature ionic liquids (RTILs) are intriguing solvents, which are recognized as "green" alternatives to volatile organics. Although RTILs are nonvolatile and can dissolve a wide range of charged, polar, and nonpolar organic and inorganic molecules, there remain substantial challenges in their use, not the least of which is the solvents' high viscosity that leads to potential mass transf...
متن کاملCarbon nanotube composites
Carbon nanotubes are molecular-scale tubes of graphitic carbon with outstanding properties. They are among the stiffest and strongest fibres known, with Young’s moduli as high as 1 TPa and tensile strengths of up to 63 GPa. They also have remarkable electronic properties and can be metallic or semiconducting depending on their structure and diameter. There is currently great interest in exploit...
متن کاملCarbon Nanotube Polymer Composites
Figure2 While there are limitless applications for these materials, we are interested in radiation shielding and radiation resistant materials for use in the space industry. Initially, we focused on optically transparent single wall nanotoube (SWNT) polymer composites (2-5). Three different in situ polymerization/sonication methods, heat, light and gamma radiation, were used to produce poly (me...
