| Résumé : |
The high cost of polymer precursors, usage of organic solvents and/or energy consumption during carbonization post-processes has limited the use of carbon fiber systems for every day applications. Here, nonwoven nanofiber mats are developed utilizing the Forcespinning technology and subsequently exposed to acid vapor induced dehydration and low temperature carbonization (T < 800 °C) processes to produce multifunctional fine carbon fibers. This method allows for the production of highly porous nonwoven carbon cloths or yarns with micro- and mesoporosity. The fiber diameter can be tuned in the range of hundreds of nanometers to several microns. Thermophysical and microstructural characterization indicate graphitic formation due to carbonization that occurs during the chemical and heat treatment. The developed system shows high electrical conductivity, high surface area, thermal stability, hydrophobicity, and oleophilic behavior. |
