Description
DESCRIPTION
A SILICA/CARBON NANOFIBER COMPOSITE NONWOVEN SURFACE Field of the Invention
The present invention relates to nonwoven surfaces comprised of silica/carbon composite nanofibers obtained by electro spinning method and carbonization process.
Background of the Invention
Many studies have been conducted on use of composite materials comprised of carbon nanofibers obtained by electro spinning method in lithium-ion batteries and as electrode material in super capacitors due to the fact that they have high electrical conductivity and high surface area.
For this purpose, polyacrylonitrile (PAN) polymer is firstly dissolved in DMF solvent thereby preparing a viscose solution and then a nonwoven surface comprised of PAN nanofibers is obtained from this solution by electro spinning method. The obtained PAN nonwoven surface is subjected to carbonization process thereby enabling conversion of PAN nanofibers into carbon nanofibers. However, flexibility of the obtained carbon nanofiber nonwoven surfaces is very low due to the fragile structure of the carbon nanofibers. Use of these fragile fibers in this state in batteries and super capacitors, which will be produced for flexible or foldable electronic devices, is not possible.
In this study, nonwoven surfaces, which are comprised of silica-carbon composite nanofibers obtained by electro spinning method and carbonization process, are produced. By means of the nanosized silica component doped to the nanofiber
structure, the carbon nanofibers obtained by electrospinning method are obtained with high degree of flexibility.
