Description

technical field [0001] The invention relates to the technical field of conductive thin films, in particular to a device and method for directly manufacturing conductive thin films at room temperature. Background technique [0002] Traditional printed circuit board and integrated circuit technology usually consume energy, water, consumables, complex processes, and cause environmental pollution. For this reason, in recent years, the realization of thin film circuits directly by printing has attracted great attention from all over the world. The key to this type of technology lies in printing patterns and electronic ink technology. So far, in the field of printed electronics, almost all methods still cannot achieve one-step molding, and often require the use of chemical reactions, high-temperature annealing and other steps to realize the manufacture of conductive films. However, we know that more and more electronic devices are developing in the direction of flexibility and u...
