Abstract To improve the oxidation resistance of carbon fibers, a series of carborane-containing polymer-based coatings were prepared. The oxidation resistance and microstructure of the coatings were investigated. According to XPS, FT-IR and XRD analysis, the high oxidation resistance of the polymer-based coatings was attributed to the boron oxide protective layer formed from the oxidation of carborane groups in the coating. Ceramic coatings were prepared from heat treatment of polymer-based coatings under argon at 1300 °C for 2 h. The great oxidation resistance of the ceramic coating was attributed to the existence of boron carbide in coating.

含碳硼烷聚合物对碳纤维的氧化保护

摘要 为提高碳纤维的抗氧化性，制备了一系列含碳硼烷的聚合物基涂层。研究了涂层的抗氧化性和微观结构。根据XPS、FT-IR和XRD分析，聚合物基涂层的高抗氧化性归因于涂层中碳硼烷基团氧化形成的氧化硼保护层。陶瓷涂层是由聚合物基涂层在氩气下在 1300°C 下热处理 2 小时制备的。陶瓷涂层的良好抗氧化性归因于涂层中碳化硼的存在。
