Abstract
PFI mill was used to prepare PBO fibrils from PBO fiber. With the help of the observation of SEM and the measure of water retention value as well as the analysis of specific surface area, it was found that the milling parameters, including the beating rotation number, beating spacing, beating pressure and beating concentration, influenced the fibrillation of PBO fiber. The processing parameters were studied. The optimal milling conditions were obtained: beating rotation number of 40000-50000r, spacing of 2.4mm, pressure of 4.89N/mm, and concentration of 7.5%. The prepared PBO fibrillar fiber has high specific surface area of 5.001m2/g, while the original PBO fiber has only a specific surface area of 0.476m2/g.
