| titleOfInvention | Polyparaphenylene benzo dioxazole fiber containing fluorine on surface and preparation method thereof |
| abstract | The invention discloses a polyparaphenylene benzo dioxazole fiber containing fluorine on surface, which is prepared through the following steps: the body of the polyparaphenylene benzo dioxazole fiber is treated by using a hydrogen fluoride gas, then is mixed by using fluorine/oxygen/inert gas, is subjected to fluoridation for 10 seconds to 2 hours at 5-150 DEG C, and finally is stored in air atmosphere for at least one hour. A contact angle between the surface of the obtained fiber and water is 60-90 degrees, the interlaminar shear strength of a composite material prepared from the fiber and epoxy resin is 30-45MPa, the tensile strength of an impregnated filament is 5.0-5.3GPa, and the tensile modulus is 264-280GPa. The polyparaphenylene benzo dioxazole fiber containing fluorine on surface is high in surface activity, interfacial interaction between the fiber and matrix resin is strong, the interlaminar shear strength of the composite material prepared by using the fiber can be improved by 50-125%, the tensile strength of the impregnated filament is improved by 4-10%, and the modulus is improved by 10-16%. According to the invention, the fluorination rate is high, the treatment time is short, the process is simple and controllable, the cost is relatively low, and the fiber has relatively strong application prospect. |
