项目摘要

Powdery materials are available in many industrial materials and products. In order to develop the more attractive powdery materials, surface modification of powdery materials is one of the useful method. However, the conventional method was only the wet process which has some problem such as disposal of waste solution, and limiting of the modified materials. Therefore, a new RF sputtering system installed with a hexagonal-barrel was developed for modifying the surfaces of powdery materials in dry process, named as barrel-sputtering system.The validity of this system was examined for surface coating of metal, ceramics, polymer and ionic crystal powders with different grain shapes and sizes. It was found that the surfaces of powder grains could be uniformly coated with metal, alloys and oxides layers, regardless of their shapes. In addition, the size of powder grains was applicable from several centimeters to several hundred nanometers. Moreover, the form of coating materials was controlled between a thin layer and the nanoparticles.For example to develop the functional powdery materials, the electrochemical catalyst as the usage in the polymer electrolyte fuel cell was prepared by using the system. The carbon black powder modified with Pt-Ru nanoparticles showed the excellent performance in comparison with the catalysts prepared by the conventional wet process.

粉状材料可用于许多工业材料和产品中。为了开发更有吸引力的粉体材料，对粉体材料进行表面改性是一种有效的方法。然而，传统的方法仅是湿法，存在废液处理和改性材料有限等问题。为此，研制了一种用于粉末材料表面干法改性的六角筒式射频溅射系统，即筒式溅射系统，并对金属、陶瓷、聚合物和离子晶体等不同颗粒形状和尺寸的粉末进行了表面改性实验。研究发现，无论粉末颗粒的形状如何，其表面都可以均匀地覆盖金属、合金和氧化物层。此外，粉末颗粒的尺寸适用于从几厘米到几百纳米。此外，涂层材料的形态控制在薄层和纳米颗粒之间。例如，为了开发功能性粉末材料，利用该系统制备了用于聚合物电解质燃料电池的电化学催化剂。与传统湿法制备的催化剂相比，Pt-Ru纳米粒子改性炭黑的催化性能优异。
