奈米含能材料研究聚焦於燃料、氧化劑與界面結構如何影響點火與反應傳播,並以可控制程與可重現量測建立材料—反應關係。Nanoenergetics research focuses on how fuel, oxidizer, and interfacial structure influence ignition and reaction propagation, using controlled fabrication and reproducible diagnostics to build material–reaction relationships.
在 Al/CuO、Al/MoO₃ 等鋁基奈米熱劑中,顆粒尺度、原生氧化層、燃料—氧化劑界面結構與組裝方式共同決定點火、反應傳播與壓力生成。本方向以保護層、配位分子或含氟官能化處理改質鋁顆粒表面,系統比較其對氧化層結構、儲存穩定性與反應路徑的影響,並以電泳沉積、可印刷熱劑漿料等技術將熱劑組裝於金屬網格、銅線與微通道上,朝兼顧穩定性與反應性能、可應用於焊接與小尺度反應元件的設計原則推進。In aluminum-based nanothermites such as Al/CuO and Al/MoO₃, particle size, native oxide layer, fuel–oxidizer interfacial structure, and assembly method jointly determine ignition, reaction propagation, and pressure generation. The work modifies aluminum surfaces with protective layers, coordinating molecules, or fluorinated functionalization, comparing their effects on oxide structure, storage stability, and reaction pathways, and assembles thermites onto metal meshes, copper wires, and microchannels by electrophoretic deposition and printable pastes — building toward design principles that balance stability and reactivity for welding and small-scale reactive components.
以 Al/CuO、Al/MoO₃ 為主要系統,系統改變顆粒尺度、表面改質配方(如三苯基膦、三氟乙酸鹽)、燃料—氧化劑當量比與組裝形式(鬆散粉末、銅網格、微通道、可印刷漿料);樣品以濕式化學合成與表面包覆、電泳沉積及 CuO 奈米線基板生長製備。以 TGA/DSC、高速影像、壓力量測與 SEM 萃取點火與反應起始溫度、燃速、熱釋放、壓力上升速率與殘留物形貌,並連結製程與界面結構,判讀氧傳輸、界面反應、保護層分解或產物層形成等限制步驟。With Al/CuO and Al/MoO₃ as the primary systems, the work varies particle size, surface-modification chemistry (e.g., triphenylphosphine, trifluoroacetate), fuel-to-oxidizer ratio, and assembly form (loose powder, copper mesh, microchannel, printable paste), preparing samples by wet-chemistry synthesis and surface coating, electrophoretic deposition, and CuO-nanowire substrate growth. TGA/DSC, high-speed imaging, pressure measurement, and SEM yield ignition and onset temperatures, burn rate, heat release, pressure-rise rate, and residue morphology, which are linked back to processing and interfacial structure to identify the rate-limiting step — oxygen transport, interfacial reaction, protective-layer decomposition, or product-layer formation.
