Abstract:

We report results on the conductivity of conductive ink based on copper phthalocyanine, which contain different organic solvents, i.e. dimethylsulfoxide (DMSO) or THF and with different percentage of copper phthalocyanine. Conductive inks were prepared from the copper phtaloyanine by dispersion of the conductive pigment in a screen printing paste. A Variety of patterns have been developed with different percentages of CuPc on a cotton substrate using the screen printing technique. Simultaneously, the presence of solvent residue in the printed pattern also resulted in poor control of the morphology and conductivity of the pattern. The solvent effect on copper phtalocyanine dispersion’s was studied by UV visible spectroscopy and the minimum sheet resistance of printed circuit board was reached at about 3% of CuPc in THF and DMSO with 1 M?cm and 1.8 M?cm respectively.
