Abstract: Ultrasonicassistant electroless copper plating of bamboo charcoal was investigated with a reduction method in which copper sulphate is used as a main salt and formaldehyde as a reducing agent. The structure and elements of copper plated bamboo charcoal surface were analyzed with SEM and EDS. Results showed that the excellent copper plated bamboo charcoal was obtained by using the small charcoal powder (particle size <0.08 mm) and loading ultrasonic after 5 min at the beginning of the plating. The copper plated charcoal showed a high copper weight percentage on the surface (32.3 %) and resistance (0.16 Ω·cm) under the optimum parameters: 15 g/L of copper sulphate, 25 mL/L of formaldehyde, pH=12, plating temperature 60 ℃, and ultrasonic time 20 min. Surface area of the charcoal was also reduced after the copper plating.
