叠氮苯并咪唑偶联剂增强国产芳纶Ⅲ/聚三唑树脂复合材料界面
|
Abstract:
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2.1wt% 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. 特种功能高分子材料及相关技术教育部重点试验室（B类）开放基金上海市重点学科项目编号（B502）
