“…Recently, Lee et al demonstrated the application of SPG thin film assembled with oppositely charged rGO as a transparent, conducting electrode for an organic light emitting diode, however, the performance was found to be inferior to ITO [48]. R s of 2.5 k /sq is obtained at Tr of 75%.…”

“…This precisely controlled deposition of ingredients has already been used to generate superior gas barrier films. LBL film properties providing high transparency and gas barrier properties can be precisely controlled by tailoring concentration, temperature, and pH of the polyelectrolyte solution [12][13][14][15].…”

In this study, we present a facile method of fabricating graphene oxide (GO) films on the surface of polyimide (PI) via layer-by-layer (LBL) assembly of charged GO. The positively charged amino-phenyl functionalized GO (APGO) is alternatively complexed with the negatively charged GO through an electrostatic LBL assembly process. Furthermore, we investigated the water vapor transmission rate and oxygen transmission rate of the prepared (reduced GO [rGO]/rAPGO) 10 deposited PI film (rGO/rAPGO/PI) and pure PI film. The water vapor transmission rate of the GO and APGO-coated PI composite film was increased due to the intrinsically hydrophilic property of the charged composite films. However, the oxygen transmission rate was decreased from 220 to 78 cm 3 /m 2 ·day·atm, due to the barrier effect of the graphene films on the PI surface. Since the proposed method allows for large-scale production of graphene films, it is considered to have potential for utilization in various applications.

“…1.). The chemical structure of AgGO nanocomposite consist of negatively charged functional groups such as hydroxyl and carboxyl group, delocalized π electrons within the aromatic ring and oxygen containing group [33,34]. The adsorption mechanism can be explained by different types of interaction such as hydrogen bonding, electrostatic interactions and electron donor-acceptor (EDA) interaction.…”
