Kneading process is used to prepare high-viscosity slurries, however, the optimal kneading conditions are still unclear. In this study, we discussed the effect of the kneading process parameters, such as the gap and the rotation speed of the rolls, and the pass number, on the particles dispersion in the slurry for the conductive adhesive. The flow behavior of the conductive adhesive slurry and the volume resistivity of its dried film were investigated. It was found that as the yield stress of the slurry increased, the volume resistivity of the dried film also decreased due to forming an effective conductive network of carbon particles sufficiently. When the shear stress applied to the slurry increased by decreasing the rolls gap, the standard deviations of the slurry apparent viscosity and the volume resistivity of the film decreased while the volume resistivity itself increased. Thus, it can be concluded that the gap and the rotation speed of rolls must be controlled properly in order to adjust the shear stress applied to the slurry for both low electric resistance and small standard deviation.
