Study on Process of Preoxidation and Carbonization for PAN-based Electrospinning Carbon Nanofiber Mat
2009
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.
