Looking back, the Chinese ink has had a long history, making its presence through paintings and played a crucial role in the Chinese culture. Investigation studies on Chinese ink have shown that the Carbon black particles within is known to have a conductive effect on Chinese ink. In this study, a special conductive ink is formulated by using Chinese ink as a raw material and the addition of Carbon Nanotube (CNT) powder into a mixture. As such, a comparison of dispersion techniques of CNTs was carried out and it was revealed that a good dispersion of CNTs can be achieved through a simple approach of manual mortar pestle milling. Further experimentation on percolation threshold revealed that the percolation values for the different paper based MWCNT-composites are 0.01wt% and 0.07wt% for filter paper and commercial A4 paper respectively.
