In order to achieve the acquirement of flexible displayer, such as e-paper and touch screen, and to reduce the cost of
conductive printing ink, the application of conductive polymer in printing ink is studied, and conductive flexible layer is
acquired. The effect of N, N-dimethylformamide, glycerol, deionizer water, and pH value on the performance of
water-based nano conductive polymer ink is studied by the second doping of conductive polymer nano suspension. The
effect of various polymers on the conductivity of printing ink is researched by adding various polymer resins. At last,
printing performance of the conductive polymer ink is tested by some printing methods, such as screen, and offset
printing. Conductive printing layer which can be compared with the traditional conductive ink in the conductivity is
acquired and the conductive layer is waterproof.
