Overview |
Description |
Nano-copper colloidal particles are widely used in catalysis, magnetic fluid, lubrication and other fields because of their specific physical and chemical properties. Nano copper powder and colloidal copper are prepared by variable current laser ion beam gas phase method, which has large industrial output, spherical shape, uniform particle size, high crystallinity, high product purity, high surface activity, easy to disperse and industrial application. |

In the field of printed electronics, copper nanoparticle (Cu NPs) ink is the most promising cost-effective candidate to replace silver ink. In addition, the sintering process can be greatly accelerated through photonic sintering technology of copper-based conductive inks, while local high temperatures can be achieved in printed circuits without affecting the plastic substrate. Photonic sintering under optimized conditions led to high electrical conductivities (20% of the bulk Cu value), combined with a good adhesion to the substrate.
Performance evaluation of Cu NPs ink
· The inks were tested on different rigid and flexible substrates, namely: borosilicate glass and soda lime glass, polyethylene naphthalate (PEN) foil, and polyethylene terephthalate (PET) foil.
· Surface modification upon different substrates was performed using a UV-ozone setup PR100 e Ultra Violet Products (UVP) for 5 min. Nitrogen plasma treatments were performed using a PVA TePla 300 Microwave Plasma System for 2 min at 600 W, 2.54 GHz and under reduced pressure (0.6 mbar). The inkjet printing performances of the three inks were tested using a DMP 2830 Materials Printer.
· Sintering was performed in a two-step approach: The first step was a fast thermal pre-treatment in a Memmert hot air oven for 10 min at 80 °C or 5 min at 100 °C in air. Under these conditions, well dried samples were obtained, which were subjected to the second step, photonic flash sintering.
