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°C（BPF：184°C），熱裂解Td-5溫度達到428°C（BPF：358°C），以及彎曲破壞強度達到82.7 MPa（BPF：58.2 MPa）。

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°C, 428°C and 82.7 MPa respectively, which are much higher than the corresponding values of 184°C, 358°C and 58.2 MPa for BPF.
