Abstract
In the present work, the choice of the nano carbon black and optimum mixed ratio and effectiveness of the mixed carbon black to get a raw data for a manufacturing method of conductive complex board. Optimum mixed ratio of paper sludge & water was 1 : 2.5 for reformations. HB-41-Y was cheaper than Super-P with the single carbon black. Also electric conductivity of HB-41-Y($6.406{\times}10^{-2}\;{\Omega}cm^{-1}$) was about 6.5 times higher than Super-P($9.741{\times}10^{-3}\;{\Omega}cm^{-1}$) at 20 wt% carbon black. This time optimum mixture ratio of the paper sludge and the carbon black to be about 15 wt%, optimum mixed ratio HB-41Y and Graphite about 3:1 and its electric conductivity was $5.824{\times}10^{-2}\;{\Omega}cm^{-1}$.
