Abstract:

Based on the research of the droplet drying process on surfaces with different wettability, controllable nanoparticles assembling, and stereo structures patterning were achieved. [1] By controlling the droplet spinning motion and the movement of the vapor-solid-liquid three-phase contact lines, the basic units from 0D to 3D structures (dot, line, plane, and stereo structures) via the printing technology can be precisely fabricated. [2] Accordingly, the functional nanoparticles are assembled into desired patterns with single nanoparticle resolution. With the assembly of metal nanomaterials via the printing process, patterned linear or curved 1D/2D structures on diverse substrates are achieved.[3] The desirable patterns contribute remarkable applications in sensitive electronic skin, multi-layer circuits, ultra-integrated complex circuits, solar cells, soft actuators and biological chip.[4] These achievements are benefited from the fundamental research in interfacial wettability manipulation, morphology control of drying droplets, as well as functional nanomaterial fabrication, which found the theoretical and technical system of Green Printing Technology.
