چکیده مقاله
Polyacrylonitrile PAN fibers with unique properties are becoming increasingly crucial as precursors for the fabrication of carbon fibers Here, we recommend providing PAN fiber to improve the homogeneity and thermal stability of the fibers Adding a prearranged amount of water 4 vol % as nonsolvent to the PAN solution, followed by wet spinning, has prepared precursor fiber with high thermal properties and unique graphitic order Differential scanning calorimetry DSC and Thermogravimetric analysis TGA results illustrate that PAN/H2O precursor fiber has higher thermal decomposition temperature, enhanced residual weight, and diminished heat release rate, a promising precursor for the evolution of high performance composite fibers
