Inkjet priting of manufacturing printed circuit board(PCB) have attracted a great interest of low-cost, environmental friendly and simple process. We focused on the preparation of conductive ink containing copper nanoparticles that are inexpensive material and have high conductivity. But copper is easily oxidized. Cu nanoparticles(5~20nm) were synthesized using capping agents based on amine or thiol and sintered at 200 ℃ under hydrogen atmosphere for 2h. The sintered Cu nanoparticles were obtained in a 20 μΩcm specific resistance and characterized by TGA, SEM, TEM, EDX, and XPS. |
