摘要：

A gravure offset printing process has been developed for Ag-filled polymer conductor ink. Pad printing and roller type printing have been used. Curing and electrical properties have been studied. A roller type of gravure offset printing has been used to evaluate the printing process and pad printing to print on the non-planar substrates. Based on differential scanning calorimetry (DSC) and resistivity measurements during ink curing, it was found that the ink had an optimum curing temperature of 140 degreesC. Square resistance of 300 and 150 mum wide lines can be as low as 20 and 28 mOmega/sq., respectively, for 7-8.5 mum thick line. The minimum line width was 70 mum. This minimum line width can be reduced with different ink solvents, but in this case the line thickness suffers and the square resistance increases, respectively. (C) 2003 Elsevier B.V.
