摘　　要：将双酚A型苯并噁嗪(Ba)、双噁唑啉(1,3-PBO)和氧化石墨烯(GO)在室温下进行物理共混,再将共混物逐步升温热固化制备了GO/Ba/1,3-PBO树脂纳米复合材料。红外光谱证实Ba、1,3-PBO与GO之间已经发生反应,热重分析表明,随着GO含量增加,GO/Ba/1,3-PBO树脂纳米复合材料的热稳定性得到显著提高。GO的添加能明显增强苯并噁嗪-双噁唑啉树脂的力学性能,当仅添加0.3%的GO时,复合材料的弹性模量和拉伸强度较纯树脂分别增加了146.7%和127.8%。GO/Ba/1,3-PBO树脂纳米复合材料的吸潮率也显著降低。Bisphenol-A type benzoxazine(Ba), bisoxazoline(1,3-PBO) and graphene oxide(GO) were physically blended at room temperature. GO/Ba/1,3-PBO resin nanocomposites were obtained by step thermal curing of the mixture composed of Ba, 1,3-PBO and GO. FT-IR conforms that the reaction among GO, Ba and 1,3-PBO occurred. The results of TGA illustrate that the thermal stability could be improved with the increase of GO content. The addition of GO could obviously enhance the mechanical properties of benzoxazine-bisoxazoline resins. Comparing with pure resin, when the mass fraction of GO is only 0.3%, the elastic modulus and tensile strength of the composite are increased by 146.7% and 127.8%, respectively. The humidity absorption ratio of GO/Ba/1,3-PBO resin nanocomposites is also decreased significantly.
