      • Abstract
    • The processing technology of electroless copper plating on graphite powders by iron powder method and formaldehyde method were studied and evaluated.The iron powder method could produce highly covered copper/graphite powders with 25%-75% copper under processing following conditions:graphite powders being pretreated by complex surfactants,plating solution added slowly,graphite and iron powders agitated at 40-60 ℃,electroless copper plated for 15-20 minutes at 1.5-2.0 pH and dried at 50 ℃.Sensitization and activation processes were very important stages in formaldehyde method.Because of the expensive reagent and low covering rate of copper/graphite powders and poisonous by-product in the formaldehyde method,the iron powder method is recommended.
