PREPARATION OF MICRO-NANO METAL MATERIAL WITH BIOLIMITED FORMING TECHNOLOGY
生物约束成型与化学沉积制备Cu微米杆材料

Cu nano-particles and homogeneous Cu coating on Nocadia surface studied by microbiological method and surface analysis technology were prepared by electroless deposition method with appropriate surfactant. 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.
