摘　　要：In this work, the surface modification of poly （1, 4-phenylene-cis-benzobisoxazole） （PBO） fibers by O 2 /Ar coaxial atmospheric dielectric barrier discharge was investigated, as well as the interfacial adhesion properties of modified PBO fibers/epoxy composites. The results indicated that the contact angle decreased remarkably from 84.7 to 63.5 after 3 min O 2 /Ar plasma treatment. SEM and AFM images showed that the surface of the treated PBO fibers became rather rough. In addition, XPS results suggested that the polar functional group （O=C- O） was introduced on the surface of the treated PBO fiber. The interfacial adhesion test showed that the interfacial shear strength （IFSS） and the interlaminar shear strength （ILSS） increased significantly by 63.54% and 130%, respectively. Moreover, the excellent tensile property of the PBO fibres was well preserved.In this work, the surface modification of poly （1, 4-phenylene-cis-benzobisoxazole） （PBO） fibers by O 2 /Ar coaxial atmospheric dielectric barrier discharge was investigated, as well as the interfacial adhesion properties of modified PBO fibers/epoxy composites.
