| 中文摘要: |
| 聚对苯撑苯并二噁唑(PBO)纤维因其比强度高、比模量高、耐热性好、阻燃性好以及优异的介电性能，现已在安全防护、建筑汽车等领域得到广泛应用。由于PBO纤维表面光滑、化学惰性，导致其与基体树脂界面结合差，进一步影响复合材料的整体性能，这大大限制了PBO纤维优异综合性能的发挥，所以对PBO纤维表面进行改性处理显得尤为重要。介绍了近年来国内外针对PBO纤维不同表面改性方法及对应复合材料性能改善程度的研究进展，从PBO纤维改性方法的分类入手，阐述了各种方法的基本原理。通过对这些处理方法的比较，阐述了国内PBO纤维表面改性的研究进展，指出了国内外在PBO纤维表面改性处理上的差距，为未来的发展方向提供了参考。PBO纤维表面改性方法包括化学刻蚀法、等离子体处理、表面涂层法、化学接枝法、紫外刻蚀法、上浆剂处理等。各种改性技术各有利弊，在选择改性方法时，理应考虑达到工艺快捷有效、经济环保和无损纤维性能等指标。未来，在PBO纤维表面改性的处理方法领域，将逐步向绿色环保的上浆剂处理方向发展。 |
| 英文摘要: |
| PBO fiber has become the ultimate choice in many fields because of its high specific strength, high specific modulus, good heat resistance, good flame retardant and excellent dielectric properties, and has been widely used in aerospace, national defense weapons, safety protection, construction and automobile fields. Because the surface of PBO fiber is smooth and chemically inert, the interface between PBO fiber and matrix resin is poor, which further affects the overall performance of the composite material, and greatly limits the play of the excellent comprehensive performance of PBO fiber, so it is particularly important to modify the surface of PBO fiber. In this paper, the research progress of different surface modification methods of PBO fibers and the improvement of composite properties in recent years were reviewed. Surface modification was mainly made to change the chemical composition and structure of the surface, improve the number of polar groups and reactive groups; change the surface morphology, improve the roughness and specific surface area; increase the surface free energy and improve the surface wettability. All the above modification effects must minimize the negative effects on the bulk properties of fibers. Finally, it was pointed out that the current surface treatment methods of PBO fibers were still insufficient, and it was necessary and urgent to find a green and efficient modification method. In recent years, with the development of fiber surface modification technology, PBO fiber modification methods have been fully developed, and the corresponding application fields have been expanded. In this paper, the different surface modification methods of PBO fiber and the improvement of the properties of composite materials were introduced. Starting from the classification of PBO fiber modification methods, the basic principles of each method were expounded, and the advantages and disadvantages of each method and the scope of application were clarified. Based on six modification methods, the surface modification methods of PBO fiber at home and abroad were investigated. By comparing these treatment methods, the research progress of PBO fiber surface modification at home and abroad was confirmed, the gap between domestic and foreign PBO fiber surface modification treatment was clear, and the future development direction was pointed out. PBO fiber surface modification methods include chemical etching, plasma treatment, surface coating, chemical grafting, ultraviolet etching, and sizing agent treatment. Each modification technology has its own advantages and disadvantages. When selecting a modification method, it is required to consider the fast and effective process, economic and environmental protection and non-destructive fiber properties. The surface treatment method of sizing agent can meet the above requirements. In recent years, the introduction of active nanoparticles such as graphene oxide, carbon nanotubes and silica into sizing agents to improve interface adhesion has become a research focus. The prepared nanocomposites not only have stronger interface, but also show many attractive functions, such as photothermal conversion, interface self-healing, etc. In addition, as a non-damaging method, surface sizing is an ideal method to achieve uniform UV shielding or light absorption ability on the surface of PBO fiber, which can effectively reduce UV intensity and block UV irradiation. In the future, in surface modification treatment of PBO fiber, the direction of environmental protection sizing agent treatment will be gradually developed. |
