溶液浸渍法制备镍金属布的研究

Preparation of Nickel Metal Cloth by Solution Dipping Process

以涤纶布和粘胶纤维布为基体,采用溶液浸渍法并在氢气气氛下还原烧结制备了镍金属布。用扫描电子显微镜、X射线衍射研究了不同工艺对镍金属布显微结构和相成分的影响,并通过TG-DTA分析研究了还原烧结过程中的反应机制。结果表明:选用粘胶纤维布作为基体,在NiCl2溶液中浸渍后,置于氢气气氛中900℃还原烧结,即可制备出连续、完整、柔韧性较好的镍金属布。

Polyester cloth and viscose fiber cloth used as precursors were treated by solution dipping process. After drying they were reduced and sintered in hydrogen atmosphere and finally nickel metal cloth was obtained. The effects of sintering systems on the microstructure and phases of the nickel metal cloth were studied by SEM and XRD. The reaction mechanism of the reduction sintering was investigated by TG-DTA analysis. The results show that the complete, continuous and flexible nickel metal cloth can be prepared when the viscose fiber cloth used as precursor is dipped in the NiCl2 solution and then sintered at 900 oC in hydrogen atmosphere.
