CONTROLLED GROWTH OF CARBON NANOCONES ON CARBON FIBERS (S)/ FABRIC AND METHOD AND SYNTHESIS THEREOF

摘要

The present invention relates to a process for uniform coating of carbon nanocones (CNCs) on long/short carbon fiber(s)/fabric using various transition metal catalyst(s) i.e., iron (Fe), cobalt (Co), nickel (Ni), ruthenium (Ru), rhodium (Rh), palladium (Pd), iridium (Ir), platinum (Pt), chromium (Cr), tungsten (W) and mixed gases. A method for coating of carbon fiber(s)/fabrics includes combining of nanomaterials(s) made up of transition metal(s) and/or carbon nanocone materials and a fiber material made up of a carbon material, forms a coated carbon fiber through chemical vapour deposition (CVD) technique at elevated temperature. The carbon nanocone (CNC) coated carbon fiber is characterized through surface area, scanning electron microscopy (SEM), transmission electron microscopy (TEM), voltage-vs-current characteristics (V-I), thermogravimetric analysis (TGA), X-ray diffraction studies, energy dispersive X-ray analysis (EDAX), etc. The present invention also discloses various conditions used to coat transition metal catalyst(s) and carbon nanocones on the surface of long/short carbon fiber(s)/fabrics. The CNC coated carbon fiber/fabric is used to make a novel polymer based hybrid nanocomposites to see its performance in structural applications. The performance of CNC coated carbon fiber is compared with as-received carbon fiber (uncoated fiber).
