Study on Process of Preoxidation and Carbonization for PAN-based Electrospinning Carbon Nanofiber Mat

The PANis electrospun to nanofiber mat,and the mat is stabilized and carbonized in order to get carbon nanofiber mat.Thermogravi metric analyzer,electronic universal testing machine,field emission-scanning electron microscope,infrared spectrometer and X-ray diffraction meter are employed to characterize the nanofiber mat,the stabilized nanofiber mat and carbonized nanofiber mat.Based on the above characterization,weight loss and chan-ges of mechanical properties and structural changes during thermal treat ment process are discussed.
