Electrochemical and electrochromic behaviors of polyaniline-graphene oxide composites on the glass substrate/Ag nano-film electrodes prepared by vertical target pulsed laser deposition

Charge transport mechanism of thermally reduced graphene oxide and their fabrication for high performance shield against electromagnetic pollution

“…Along with graphene, reduced graphene oxide has also gained tremendous attention due to its superior mechanical, electrical, optical, chemical and thermal properties [4,13,14]. Due to these superior properties, it is a promising candidate for many potential applications such as supercapacitor [21], non-volatile memory devices [22], electrochemical and electrochromic devices [23], gas sensors [24] and solar cell devices [25]. Along with these applications, the excellent electrical properties and high surface area [4,13,14] can make reduced graphene oxide a potential material for the electromagnetic shield to absorb incident EM waves.…”

Covalent Bonding of PANI and p‐Phenylenediamine‐Functionalized GO Using N,N′‐Dicyclohexylcarbodiimide as Dehydrating Agent for Electrochromic Applications

“…At the same time, electrochromic behaviors of graphene/PANI nanocomposites have caused some researchers attention. Ji Y used Czochralski method to fabricate PANI‐GO composites film. The obtained PANI‐GO shows more remarkable characteristic peak shift and lower redox potential than the undoped PANI.…”

Photoresponsive Smart Coloration Electrochromic Supercapacitor

“…

systems do not show photoresponsive coloration, resulting in lack of adaptive modulation of sunlight, i.e., "smart color tuning." [8][9][10][11] In addition, the high electrical resistance of current collectors in electrochromic devices, which causes deceleration of coloration by slowing down the electrons to cause delays in electrochromic-colorswitch time, and the lack of transparency in the conventional current-collector materials are also problematic.As a solution to the aforementioned challenges in development of electrochromic system for a flexible, wearable system, a flexible electrochromic device can be integrated together with a flexible supercapacitor that can first eliminate the problem associated with the need for an external power source. Electrochromic systems to be applied in wearable and portable electronics should be able to demonstrate efficient and reversible electrochromic coloration while retaining its performance, even throughout repeated mechanical straining.

In development of electrochromic devices suitable for wearable, portable electronics, there are several obstacles to overcome.
