在电爆法制备纳米粉基础上,开发了一种新的电爆制备亲油纳米粉体法,它能使金属丝在爆炸的瞬间,浸润到液体油中,减少纳米粉体的团聚。研究表明,油浸润条件下所制得的纳米粉的分散性优于传统电爆法所制的纳米粉;制备的纳米铜粉平均粒径为30～50 nm,随电极电压升高,粒径有减小趋势。 On the basis of electrical explosion method to prepare nano-powder, a new kind of oil-explosive nano-powder method was developed, which can make the metal wire infiltrate into liquid oil at the moment of explosion and reduce the agglomeration of nano-powder. The results show that the nano-powder prepared under oil immersion condition has better dispersivity than the nano-powder prepared by the traditional electric explosion method. The average particle size of nano-copper powder prepared is 30-50 nm. With the increase of electrode voltage, There is a tendency to decrease.
