Research on New Method for Preparing Oleophilic Nano-copper Powder
On the basis of electrical explosion method for preparing nano-powder,a new kind of electrical explosion method for preparing oleophilic nano-powder was developed.The new methods enable the wire to infiltrate into the liquid oil in the moment of the wire explosion,and reduce the agglomeration.The research results show that the dispersion of the nano-powder obtained by oil conditions is better than the nano-copper powder prepared by traditional explosion.The prepared copper nanoparticles' average diameter is 30-50 nm,and the particle size decreases with increasing electrode voltage.
