Investigation of electrostatic atomization of a conjugated polymer (poly[2-methoxy-5-(2′-ethylhexyloxy)-(p-phenylenevinylene)]) and its film characterization for organic diode applications

The study demonstrates the electrostatic atomization behavior of polymer based solution and the fabrication of the thin film of poly[2-methoxy-5-(2′-ethyl-hexyloxy)-1,4-phenylenevinylene] polymer using electrospray deposition technology. In this study, the polymer ink was developed and was subjected to electrostatic atomization. The ink behavior under the influence of electric field was investigated and the operating envelope of the ink was explored. The film deposited through electrospray was then characterized in physical as well as electrical aspect. Finally, the organic diode with electrosprayed polymer was fabricated. The performance of the diode device was investigated by current–voltage measurement and compared with a spin-coated device.
