Presentation Abstract:

The blooming of printed electronics is promoting fashion electronic manufacture to flexible,
wearable, ultraintegrative, ultralight, transparent devices, and clean, efficient, mild
productions. Various materials were demonstrated adoption in printability. The critical
scientific challenges of the printing process are wettability manipulation and dynamics of
ink droplets. Based on the droplet drying process on the surfaces of different wettability,
controllable nanoparticles assembling and patterning could be achieved, through controlling
the movement of vapor-liquid-solid three phase contact lines. Highly precise self-assembly of
nanomaterials in the ink droplets along the vapor-solid-liquid three phase contact lines
could be accurately achieved. Significantly, the basic units (dot, line, plane and stereo
structures) via the printing technology can be precisely controlled. We achieved the silver
nanoparticles assembled conductive patterns with one nanoparticle (49±2 nm)
resolution. Our further work on assemble metal nanomaterials or graphene via feasible
printed process, patterned the various linear or curves 1D/2D morphologies and optimal
interconnects on diverse substrates. The desirable conductive patterns contribute the
remarkable application on sensitive electronical skin, transparent touch screen, multi-layer
circuits, ultra-integrated complex circuits and soft actuators. These achievements construct
the theoretical and technical system, Green Printing Technology.
