The recent dramatic progress in the printed electronics and flexible electronics, due to the universality of the substrates including the foldable and stretchable substrates, has opened a new prospect in the field of future electronics. In this paper, silver nanospheres in large-scale are synthesized, the nanosilver ink with 63.88% silver content are prepared and a new type of highly conductive and far identify distance RFID tags are manufactured. Especially there are no resin and other additives containing in our conductive ink which satisfy the rheological characteristics and process of screen printing. The tags exhibit the best radiation performance own to there is no high temperature sintering in need. The surface resistance of the tags could be 80 mΩ/, and the identify distance reach to 6.0m.

Selection Of

Graphene has drawn a lot of attention as a promising material for a conductive ink due to its high electrical conductivity and abundant source. Selection of solvent for ink formulation is crucial to obtain the desired result. In this work, microcrystal cellulose solution is investigated as alternative solvent for conductive ink formulation. Although the viability of the microcrystal cellulose solution was already presented in other works, further thorough and systematic study is highly required. Cellulose solution was prepared using microcrystalline cellulose and sodium hydroxide aqueous solution. Dispersions with different graphite-to-cellulose ratio were prepared. The exfoliation process was for sonication times of 8, 16, 24 and 32 hours. For Raman spectroscopy and 4-point probe measurement, graphene thin film was formed by drop-casting 20μl dispersion on glossy paper. Sample with low graphite-to-cellulose ratio exhibited more significant reduction in unexfoliated graphite content over the sonication time. The sufficient amount of cellulose in the dispersion leads to more effective exfoliation process. According to analysis on the Raman spectra, the exfoliated graphite could be classified as few-layer graphene with low defect content. The drop-casted thin film from dispersion with ratio of 20:1 showed sheet resistance lesser than 100 Ω/sq. The obtained results confirmed the effectiveness of microcrystal cellulose as the agent for exfoliation process.

Ink Transfer

An ink transfer process from the printing roll to the moving web was investigated using a computational fluid dynamics technique for the roll-to-roll application in the area of printed electronics. Emphasis was made on the shape of the transferred ink pattern in a realistic configuration. The shear-thinning effect of the conductive ink was treated using a generalized non-Newtonian fluid model. That is, the coefficients of the Carreau model were determined using the fluid dynamic property information of the commercially available conductive ink used in the roll-to-roll process. Also, the web handling speed was matched with that of the typical roll-to-roll process applied in printed electronics. Computational results show that the spatial variation of the shear rate is quite significant in the present configuration; therefore, the Carreau model better predicts the shape of the measurement data than Newtonian fluid in the range of the line thickness of 100–500 µm. It is also noted that the non-uniformity of the transferred ink that is experimentally observed is better predicted by the non-Newtonian model. It is conjectured that the distortion of the shape and the non-uniform distribution of the transferred ink are the prime sources for deterioration in printing quality. However, the fact that web handling speeds of up to 30 mpm (=0.5 m/s) do not significantly aggravate the degree of distortion still supports the main advantage of a cost-effective, continuously running roll-to-roll process in this speed range.
