本研究探討了超奈米鑽石和碳氮化硼複合於碳布上作為超級電容器之應用，並探討退火之後處理對此結構之影響。內文將分為兩個部分，第一部分致力於透過各種不同製程及組成原料做出被視作結構類似於石墨半導體材料的碳氮化硼(Boron Carbon Nitride, BCN)於碳布上之結構影響，並探討不同製程及組成原料對碳氮化硼於碳布上之作為超級電容器之特性，以及探討不同生長時間之超奈米鑽石(Ultra-nanocrystalline diamond, UNCD)於碳布上之均勻性與密度。第二部分旨在致力於探討碳氮化硼複合超奈米鑽石於碳布作為超級電容器之特性，並研究不同結構及不同退火條件對此種新型複合結構之影響，藉此提升超級電容器之電容值。
研究發現，以硼酸(Boric acid)、葡萄糖(glucose) 、氰胺 (Cyanamide)為原材料，並使用化學氣相沉積系統 (Chemical vapor deposition, CVD) 直接成長碳氮化硼於碳布基板上，其作為超級電容器之重量比電容值為最佳――推測是其ID / IG比值在此系列參數中具有最小值，因此得知此參數所成長碳氮化硼於碳布基板上結晶品質為最佳。
此外，研究亦發現BCN / UNCD / CC複合結構在經過退火之後處理其重量比電容值會大幅增加，並且其循環穩定性也會因此有所提升。值得一提的是，經過大氣退火後處理之樣品，其重量比電容值從原先之118.95F/g上升至121.45 F/g，循環穩定性為102.1％，有著令人驚豔的良好循環穩定性，甚至整體有著上升之趨勢。表明此種BCN / UNCD / CC新型複合結構在經過大氣退火後具有優異之循環穩定性。

This study investigates the application of Ultra-nanocrystalline diamond (UNCD) and boron carbon nitride (BCN) composites on carbon cloth for supercapacitor usage, as well as the impact of post-annealing treatment on this structure. The content is divided into two parts.The first part focuses on fabricating BCN structures on carbon cloth using various processes and composition materials, resembling a semiconductor-like material similar to graphite. The study explores the influence of different fabrication processes and composition materials on the supercapacitor properties of BCN on carbon cloth. Additionally, it investigates the uniformity and density of ultra-nanocrystalline diamond (UNCD) grown on carbon cloth with different growth times.The second part aims to examine the characteristics of BCN composite with ultra-nanocrystalline diamond on carbon cloth as a supercapacitor. It also investigates the effects of different structures and annealing conditions on this novel composite structure to enhance the capacitance of the supercapacitor.

The research findings indicate that growing BCN directly on the carbon cloth substrate using boric acid, glucose, and cyanamide as source materials through chemical vapor deposition (CVD) yields the best specific capacitance for supercapacitor applications. This is likely due to the minimum ID/IG ratio in this parameter series, indicating optimal crystalline quality of BCN grown on the carbon cloth substrate.

Furthermore, the study reveals that the specific capacitance of BCN/UNCD/CC composite structures significantly increases after annealing treatment, leading to improved cyclic stability. Notably, the specific capacitance of the samples subjected to atmospheric annealing treatment increases from the original 118.95 F/g to 121.45 F/g, with a cyclic stability of 102.1%. This demonstrates remarkable cyclic stability improvement after atmospheric annealing treatment for the BCN/UNCD/CC composite structure, even showing an overall upward .In conclusion, this novel BCN/UNCD/CC composite structure exhibits excellent cyclic stability after atmospheric annealing treatment, making it a promising candidate for enhancing supercapacitor performance.
