项目摘要
In the present study, following three types of polymer electrodes were prepared electrochemically to develop new conductive polymer electrodes having unusual doping properties for energy conversion. These electrodes are applicable to secondary batteries and direct methanol fuel cells.1. Properties of polyanilines having oxyethylene units (negative electrode of secondary battery) Electrochemical behaviors and properties of poly-(N-3, 6, 9-trioxadecyl)-aniline (poly-NTDAn) were also studied and compared with those of Poly-N-(3, 6-dioxaheptyl) aniline . The reversibility of electrochemical n-type doping-undoping reaction was much improved for poly-NTDAn, which has three oxyethylene units at N position. The molecular weight of poly-NTDAn was high (1,100,000), and the conductivity value was 0.9 mS/cm.2. Properties of self-doped polyaniline composites (positive electrode of secondary battery) Electroactive poly-aniline-2, 5-disulfonic acid (poly-ADSA) was used as a bulky dopant of polyaniline (PAn) to develop highly electroactive polymer electrodes. PAn/poly-ADSA composite was prepared by dopant exchange. The redox charge of resulting composite increased up to 120% of the value of untreated PAn by the electrochemical doping of electroactive poly-ADSA.The specific capacity was determined to be 98 Ah/kg, which is comparable to that of PAn.3. Properties of Pt/polyaniline composite electrodes (negative electrode of fuel cell) Electrocatalytic oxidation of methanol on Pt modified polyaniline electrodes was investigated to develop highly active composite electrodes for direct methanol fuel cells. Pt/polyaniline modified carbon electrodes showed higher catalytic activity towards oxidation of methanol than Pt deposited carbon electrodes. The effect of kind of protonic acids used in the electrochemical preparation of polyaniline on the oxidation current of methanol was studied. Largest oxidation current was obtained for polyanilines prepared in sulfuric acid solutions.
在本研究中,按电化学制备了三种类型的聚合物电极,以开发具有与能量转化的异常掺杂特性的新的导电聚合物电极。这些电极适用于二级电池和直接甲醇燃料电池。1。还研究了和聚-N-(3,6-二甲基磷酸)苯胺的多苯胺的特性(二级电池的负电极)电化学行为和多种化学行为和多苯基单位(二氧化二烷基) - 苯胺(poly-ntdan)的特性和性能。对于聚-NTDAN,电化学N型掺杂反应的可逆性得到了巨大改善,Poly-Ntdan在N位置具有三个氧乙烯单元。聚-NTDAN的分子量高(1,100,000),电导率值为0.9 ms/cm.2。自载聚苯胺复合材料(二次电池的阳性电极)的特性,将电活性多氨基-2,5-二磺酸(Poly-ADSA)用作多苯胺(PAN)的笨重掺杂剂(PAN)来发展高度电活性的聚合物电极。 PAN/POLY-ADSA复合材料是通过掺杂剂交换制备的。通过电化学多ADSA的电化学掺杂,所产生的复合材料的氧化还原电荷增加了未经处理的锅的值的120%。确定特定能力为98 AH/kg,与pan.3相当3。研究了PT/聚苯胺复合电极(燃料电池的负电极)甲醇对PT修饰的聚苯胺电极的电催化氧化,以开发直接甲醇燃料电池的高活性复合电极。 PT/聚苯胺修饰的碳电极比PT沉积的碳电极表现出更高的催化活性对甲醇的氧化活性。研究了用于聚苯胺的电化学制备对甲醇氧化电流的电化学制备的影响。在硫酸溶液中制备的聚苯胺获得了最大的氧化电流。
