| 中文摘要 | 本試驗成功製備出的鉬改質酚醛樹脂/氮化鋁複合材料(Mo-BPF/m-AlN),在製備過程中鉬酸鹽與酚醛樹脂(BPF)反應後形成具有Mo-O鍵結的低交聯度鉬酚醛樹脂(Mo-BPF),同時也製備出APTES表面處理的氮化鋁陶瓷材料(m-AlN),然後m-AlN與Mo-BPF混合後形成Mo-BPF/m-AlN複合材料。Mo-BPF/m-AlN、Mo-BPF、BPF藉由FTIR、DSC、DMA、TGA、SEM及彎曲破壞強度測試後,可觀察到Mo-BPF的熱性能及機械強度都有明顯高過於BPF樹脂。接著再把m-AlN微粒子混入到Mo-BPF中,由於m-AlN在Mo-BPF樹脂中顯現出良好的分散及黏結,因此能夠更加提升Mo-BPF的熱性能及機械強度。從Mo-BPF/m-AlN及BPF的測試比較後,Mo-BPF/m-AlN的玻璃轉移溫度達到245 oC(BPF:184 oC),熱裂解Td-5溫度達到428 oC(BPF:358 oC),以及彎曲破壞強度達到82.7 MPa(BPF:58.2 MPa)。 |
| 英文摘要 | Novolac-type bisphenol-F based molybdenum-phenolic resins/silane-modified aluminum nitride (Mo-BPF/m-AlN) composites were successfully prepared. In the preparation process, molybdate reacted with bisphenol-F based phenolic resins (BPF) to form a low cross-linked Mo-BPF with new Mo-O bonds. Simultaneously, a special silane-modified aluminum nitride (m-AlN) was prepared. Then, this m-AlN was fully mixed with Mo-BPF to form Mo-BPF/m-AlN. The structure and characterization of BPF, Mo-BPF and Mo-BPF/m-AlN were determined by using FTIR, DSC, DMA, TGA and SEM. The glass transition temperature, thermal resistance, flexural strength, and hardness of Mo-BPF are respectively higher than those of BPF. When the m-AlN was additionally incorporated into Mo-BPF, the well-dispersed and well-adhered m-AlN can further promote all the above-mentioned properties of the composites. Typically, the glass transition temperature, decomposition temperature at 5% weight loss and flexural strength of Mo-BPF/m-AlN are 245 oC, 428 oC and 82.7 MPa respectively, which are much higher than the corresponding values of 184 oC, 358 oC and 58.2 MPa for BPF. |
