A programmable macroscale electrical field self-assembly array device for diverse thin film applications

For a programmable mask-less patterning, we develop the novel electrophoretic deposition (EPD) method by a macroscale programmable patterning system, which has a large matrix EPD array device (2.5 x 2.5 mm(2) electrodes with 10 mu m gap; 20 by 20 electrodes pattern) and printed circuit board controllers. We demonstrate programmed diverse micro/nano size (20 nm-10 mu m) polystyrene beads pattern onto our 400 sites wafer scale chip, which carry out that individually penetrate electrical fields at each electrode. To pattern diverse materials onto non-conductive other substrate, 200 nm nano-porous nitrocellulose membrane is laid onto the system. Cy3 17 bases DNA and 40 nm biotin-coated beads with fluorophore are patterned onto nitrocellulose substrate. Furthermore, we demonstrate that 7-15 nm diameters and 0.5-10 mu m lengths carbon nanotubes (CNT) are patterned onto the nitrocellulose substrate by the system. The CNT pattern films are simply lift off from the system. Also, CNT, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) and (6,6)-phenyl-C-61-butyric acide methyl ester and poly(3-hexylthiophene) are locally patterned, through the multi layering process by the system. The multi-layered polymer device is assembled with indium tin oxide onto polyethylene terephthalate as photodetector The polymer photodetector is demonstrated by light on (2.5 x 10(-5) A at 3 V)/off condition. (3.5 x 10(-5) A at 3 V). Finally, we demonstrate the fabrication of energy storage device, which is patterned LiCoO2 (LCO)/CNT mixtures/CNT and graphite/CNT as a cathode and anode of secondary battery. The half-cell of 143.7 mu m deposited LCO mixtures is successfully operated with 112 mA/g capacity for 3 times charging/discharging cycles. (C) 2020 The Author(s). Published by Elsevier B.V.
