使用配备有六边形桶的射频溅射系统，用铂对三种不同尺寸（直径为50、12和5μm）的球形聚合物微粒的表面进行修饰。研究发现，无论颗粒大小如何，颗粒表面都可以均匀地涂覆铂层。应当注意的是，本系统可以在直径为1μm的聚合物颗粒上形成均匀的Pt层。 Pt 涂层样品的循环伏安图 (CV) 与大块 Pt 的 CV 相同，表明 Pt 层的电化学特性与 Pt 金属的电化学特性相同。 (c) 2005 Elsevier B.V. 保留所有权利。
Surfaces of spherical polymer microparticles with three different sizes (50, 12 and 5 mu m in diameter) were modified with platinum using the hexagonal barrel equipped RF sputtering system. It was found that the surfaces of particles could be uniformly coated with Pt layers, regardless of their sizes. It should be noticed that the present system made it possible to form a uniform Pt-layer over a polymer particle of 1 mu m diameter. Cyclic voltammograms (CVs) of the Pt-coated samples gave the same CV as that of bulky Pt, indicating that electrochemical characteristics of the Pt-layers are identical with those of Pt metal.
