中文摘要
製備奈米物質的技術目前十分熱門,其中具有特殊結構的奈米物質其製作方法更是繁複,本篇欲以簡易、不昂貴的方法製備奈米物質,因此採用模版製作的方法,選取具等向性圓柱狀孔洞的高分子膜,採用無電鍍法,經去除薄膜後,即可輕易的製做出具等向性的介孔管狀材料,並且此一方法頗具再現性。
本研究所製做出的鎳磷管狀電極,經熱處理後,其結晶結構會由微晶相與非晶向的混和轉變為立方晶系Ni3P與Ni兩個穩定相,其中XRD的peak間的相對強度與一般的鎳磷鍍層不同,呈相反的趨勢,當熱處理溫度由400℃增加到500℃時,Ni的(200)峰強度也隨之增加,其它則未變動,此一有趣的現象因時間因素而不做後續深入的探討,有待後人去完成。由SEM圖計算出的理論面積為平板的9倍左右,電化學特性的測試結果也與此值相近,其電化學特性與平板狀的鍍層亦十分相似。其能量密度與雙層電容雖不甚優越,但利用此一等向性的鎳磷管狀電極進行再一次的加工,如披覆活性物質,或是利用其空管中的空隙製作奈米物質都是可以更進一步的研究方向。
Abstract
Technologies of manufacturing nanomaterial are very hot now, especially the nanomaterials which have special structure. In his study, we wanted to use uncomplicated and inexpensive method fabricating nanomaterial. Therefore, we taked ‘template synthesis’ method and chosen the polymer membrane that has isotropic and cylindrical pores. Combined with electroless method, after dissolved the template membrane, we could obtained the isotropic mesopore material.
After heat treatment, the Ni-P tubular electrode in this research, its crystalline structure would change from the mixture of microcrystalline and amorphous to the Ni3P and Ni stable phases. Generally, the cubic phase Ni has the stronger peak at (111), but our Ni-P electrode has opposite phenomenon that the stronger peak is at (200). And this peak intensity became greater when heat treatment temperature increased. Because of time reason, this interesting phenomenon would be explored completely by successor. From the calculation of SEM figures, the theory area is nine times about plane electrode and the results of electrochemical characteristics tests were conformed to this value. Its electrochemical characteristics were more like plane one. Although their energy density and double capacitance were not very good for using directly, but we could use this Ni-P mesopore electrode to do another processing, such as active material mantled, fabricating nanometerial in their tubular interval, they are all the further investigate aspect about this.
