Enhanced UV Stability of PBO Fibers by Using Benzotriazole UV Absorber

Abstract:

In the present research, a sizing agent containing benzotriazole UV absorber was used as coating to enhance the UV stability of PBO fibers. The sizing coating was characterized by XPS and SEM. The effect of UV absorber on UV stability of PBO fibers was studied by an accelerated photo-aging method. The experimental results show that UV stability of coated PBO fibers was obviously improved compare to uncoated PBO fibers. After 480 h of UV exposure, the tensile strength retention and intrinsic viscosity retention of coated PBO fibers was higher than that of original PBO fibers. SEM photograph shows that no significant change of surface morphologies, meanwhile some latitudinal crack appeared on the original PBO fiber surface.
