It was found that surfactant A was superior to some other kind surfactant under the same other conditions. Nocadia dispersed in pre-processes solutions and electroless plating solutions in the synergistic action of surfactant A and agitation. Cu particles with the size of 20nm deposited on Nocadia surface successfully and formed homogeneous Cu coating with the thickness of 200nm. Nocadia remained their original rod shape after Cu nano-particles deposition. Micro-rod metal material formed of Cu nano-particels was obtained. Key words： biolimited forming technology    micro-nano material    Nocadia 收稿日期: 2006-09-06      ZTFLH:  O641   服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 刘建华 梁馨 李松梅 44.8K 链接本文: https://www.ams.org.cn/CN/Y2007/V43/I5/557 [1] Zhang D Y, Li Y Q.
