Investigation of sintering of silver lines on a heated plastic substrate in the dry aerosol jet printing

The study on dry aerosol jet printing with simultaneous sintering of deposited Ag nanoparticles 20-80 nm in size on a heated plastic substrate is presented. It is established that to achieve minimal electrical resistivity of microstructures produced of ∼200 μΩ·cm, the recommended temperature of the heated substrate is to be ∼200 °C. It is also found that when increasing the heated substrate temperature above 225 °C, formed microstructure electrical resistivity rises abruptly due to plastic substrate deformation. The result obtained is of interest in developing a one-step technology for producing electronic components on a plastic substrate. (paper)
