PREPARATION AND APPLICATION OF FLEXIBLE AND SELF-STANDING NON-WOVEN CARBON NANOFIBERS

摘要

The preparation of electrospun nanofiber mats is the first step to obtain high strength carbon nanofiber mats.The shape and mechanical properties of electrospun nanofiber mats play a decisive role in the final electrospinning of ultrafine carbon nanofiber mats.At the same time,pre-oxidationlE is also one of the important steps,which the structural change determines the structure and properties of the final carbon fiber to a great extent.As in previous studies,the stabilization process need a long time,this study found that by shortening the stabilization time,controlling the oxygen content during the stabilization process,the tensile strength of carbon nanofiber mats can be enhanced.
