In order to solve the problem that low cost cop per-based conductive ink is easily to be oxidized while sintering in air or at low temperature, which limits its wide application in flexible electronic devices, the influence of sintering process on its conductivity is studied. Conductive ink is prepared by dissolving micron-sized copper flake into mixed organic solvent. The pattern is prepared by the method of brush writing and easily operated by infrared sintering in the air. Then the conductivity and applicability of conductive pattern are further improved by the method of spraying ascorbic acid (Vc) aqueous solution on its surface several times and hot pressing to enhance its adhesion and density. Confirmed by XRT) that conductive patterns are pure copper peak both before and after sintering. The resistivity testing results show that with the increasing number of Vc aqueous solution spraying, the resistivity is on a downward trend. After 45 minutes of sintering, the pattern's resistivity greatly decreases from 3.7X10² Q • cm to 1.2X10-5 Q • cm. Tt shows good antioxidant capacity as well in the subsequent sintering process without spraying Vc. The mechanism of the action of Vc in aqueous solution has been confirmed at the sintering temperature of 50 °C and pH of 4.0. The pattern resistivity gradually decreases and maintains good stability, which proving that Vc provides a good reducing environment. Confirmed by SEM that the copper plates are more tightly bonded when the conductive pattern is offered with Vc sintering and hot pressing treatment, which contributes to the further improvement of electrical conductivity and adhesion. Tn room temperature and air, Vc aqueous solution sintering and hot pressing can effectively reduce the resistivity and greatly improve the compactness of the sintered copper based conductive ink patterns, which can be widely used in the field of flexible electronic devices.

Silver nanoparticles with nanometer size effect can improve the low temperature sintering properties, rheological properties and conductive performance of conductive paste. The addition of silver nanoparticles in the conductive paste become the hotspot of research and development for conductive paste. Tn this paper, the preparation method of silver nanoparticles was summarized, including physical method, chemical method, and biological method. The application in the solar cell conductive silver paste, conductive adhesive of electronic components connection and conductive ink was described. With the flexible printing electronic technology development as well as the heterojunction and thin film solar cells development, the nano conductive powder of silver would be the trend of the conductive paste.

With the rapid development of printing and electronic industry, it has become a hot research topic to find conductive ink that can meet requirements of products as many as possible, simplify the process and control the cost. Graphene, with its excellent conductivity, thermodynamics, optics and mechanical properties, endows flexible electronic products with higher flexibility and easy processing, which ensures the conductivity and reduces the cost. In this paper, the preparation methods of graphene ink, and the various means of graphene conductive ink adhering to substrate, as well as the existing problems were briefly introduced. The new development of graphene and its related derivative-based conductive inks were emphatically introduced. [ABSTRACT FROM AUTHOR]

The aqueous acrylic resin, aqueous acrylic emulsion, the auxiliary agent and deionized water are uniformly mixed in a certain ratio, then the prepared AgNWs/PVP(silver nanowires/Polyvinylpyrrolidone) composite is added with certain amount of water and ethanol, finally a AgNWs/aqueous acrylic conductive ink is obtained after grinding. The effect of different conditions on the ink performance is explored. The mixture of 15% AgNWs, 25% acrylic resin and 60% other materials is ground for 15 min and coated on coated paper, then dried at 150 °C for 30 s, it is found that the square resistance is as low as 0. 176 Ω/□ and the coated surface is flat. While the sintering temperature is ranging from 100 °C to 150 °C, the conductive coating still has good conductivity after 2 000 times of rubbing, or 40 times of tearing, or 1 000 times of bending resistance.
