Abstract

The invention relates to the manufacturing method of a PEDOT:PSS@ ionic liquid gel composite self-supporting flexible transparent electrode. The manufacturing method comprises the following steps of compositing a conductive polymer PEDOT:PSS and an ionic liquid monomer through an electrostatic interaction; and under light and heat conditions, carrying out polymerization crosslinking and acquiringthe PEDOT:PSS@ ionic liquid gel composite self-supporting flexible transparent electrode. The composite flexible transparent electrode has good stability and an excellent mechanical property. Shedding, fracture and other problems between the flexible transparent electrode and a substrate are overcome. The electrode has characteristics that a manufacturing process is simple; cost is low; and the electrode is stable and has good flexibility. The transparent electrode is suitable for manufacturing wearable electronic equipment, a flexible touch screen, a flexible solar cell and a flexible organicEL panel.

Description

technical field [0001] The invention belongs to the field of preparation and application of electronic devices, and relates to a method for preparing a high-performance flexible transparent electrode by compounding a PEDOT:PSS film and an ionic liquid gel. Background technique [0002] Flexible transparent electrodes play a pivotal role in the development of electronics and optoelectronics industries, and are indispensable optoelectronic functional materials for the preparation of many electronic and optoelectronic components. At present, flexible transparent electrodes are mainly prepared by chemical vapor deposition, sol-gel method, vacuum evaporation deposition and other methods on transparent organic polymer substrates (reference: J.A.Lewis et al.Science,323,1590-1593(2009 ); R.B. Kaner et al. Science, 335, 1326-1330 (2012); D.B. Janes et al. Nature Nanotech, 2, 378-384 (2007); Y. Cui et al. Nature Nanotech, 8, 421-425 (2013)). However, the flexible transparent electrod...
