Charge Transport in Conducting Polymers: Polyacetylene Nanofibres
The preparation of individual polyacetylene nanofibres has allowed a more probing investigation of the properties of polyacetylene. A significant discovery is that at low temperatures, polyacetylene nanofibres show temperature-independent Zener-type tunnelling, that we suggest is tunnelling of the conjugated-bond pattern along single polyacetylene chains. At higher temperatures, the current sho...
متن کاملBioceramic Nanofibres by Electrospinning
Nanoscale three-dimensional (3D) scaffolds offer great promise for improved tissue integration and regeneration by their physical and chemical property enhancements. Electrospinning is a versatile bottom-up technique for producing porous 3D nanofibrous scaffolds that could closely mimic the structure of extracellular matrix. Much work has been committed to the development of this process throug...
متن کاملModelling electrospinning of nanofibres
Electrospinning is based on so-called bending instability which results in an erratic spiralling motion of the liquid jet as it proceeds towards a collecting electrode, where it is eventually deposited as a mat of micro/nanosized fibres. Most electrospinning models formulated within the slender approximation rely, however, on an inconsistent description of electrostatic interactions which rende...
متن کاملPolymer Composite Nanofibres
It is known that carbon nanotubes have impressive mechanical properties and it is thought that one of the best ways to realize them is to incorporate nanotubes into composites. The highest levels of stiffness and strength are obtained for composites with the reinforcing fibers aligned in one direction. It has also been recognized that for any nanocomposite to realize its full potential in terms...
متن کاملSurface Oxidation of Carbon Nanofibres
Carbon nanofibres of the fishbone and parallel type were surface-oxidised by several methods. The untreated and oxidised fibres were studied with infrared spectroscopy, thermogravimetric analysis and XPS. Oxidation in a mixture of concentrated nitric and sulfuric acid turned out to be the most effective method for creating oxygen-containing surface groups. This treatment results not only in the...
