Abstract

The surface treatment of high modulus poly(p-phenylene-2,6-benzobisoxazole) (HMPBO) fibers was performed by using a solution of polyphosphoric acid (PPA)/absolute alcohol (EtOH) (1:1, vol:vol) under ultrasonic vibration. The chemical compositions, crystallinity, and surface morphologies of HMPBO fibers were characterized by contact angles, XRD, XPS, TGA, and SEM. Results showed that the hydrophilicity of treated HMPBO fibers was improved, and the contact angles between treated HMPBO fibers and water were decreased. The treated HMPBO fibers exhibited the slight reduction in the single fiber pull-out strength and crystallinity.
