通过分子设计制备合成了含叠氮及苯并咪唑双官能团的偶联剂 Azido-Benzimidazole(ABI),并考察了新型偶联剂对国产芳纶Ⅲ(DAF-Ⅲ)/聚三唑树脂(PTA)复合材料的界面增强作用。SEM、傅立叶变换衰减全反射红外光谱(ATR-FTIR)及 XPS分析表明,ABI通过分子结构中的苯并咪唑基团与 DAF-Ⅲ纤维形成分子间氢键,能够作用到DAF-Ⅲ上。FTIR及DSC分析表明,ABI中的叠氮基团与PTA树脂中的炔基发生反应,生成三唑环参与了PTA树脂的固化。经2.1 wt%ABI处理后,DAF-Ⅲ/PTA树脂复合材料层间剪切强度(ILSS)和弯曲强度分别较未处理时提高了62.0%和43.7%。
A new type of coupling agent Azido-Benzimidazole (ABI)containing benzimidazole and azide groups was designed and prepared in this study.And ABI was added into the domestic aramid fiber Ⅲ (DAF-Ⅲ)/polytriazole (PTA) composites to reinforce their interfacial properties. The results of SEM, Attenuated Total internal Reflectance Fourier Transform Infrared Spectroscopy (ATR-FTIR)and XPS show that ABI can bond with the fiber by intermolecular hydrogen;FTIR and DSC results indicate that the azide group in ABI can react with alkynyl in PTA and take part in the curing process synchronously.The mechanical performances of DAF-Ⅲ/PTA composite are improved greatly after ABI modification.The Inter Laminar Shear Strength (ILSS)and flexural strength increase by 62.0% and 43.7% respectively after 2.1wt% ABI treatment compared with those of untreated composites.
