“…In the development of cover encapsulation technologies in OLEDs, some researchers focused on optimization of the single element such as adhesive, substrate, cover material coupled with getter. [ 209–214 ] The others combined two elements such as adhesive/substrate together for investigation. In the following section, the advancement of single element and multi‐elements in cover encapsulation technique is reviewed, respectively.…”

“…prepared graphene oxide (GO)/poly‐diallyl dimethyl ammonium chloride (PDDA) multilayer film on polyethylene glycol terephthalate (PET) substrate by the layer‐by‐layer method. [ 213 ] Graphene was used as inorganic material deposited on polymer plastic, while the traditional UV‐epoxy and glass were still applied in adhesive and substrate. Graphene has excellent barrier properties for the permeability of any gas molecule.…”

Organic light emitting diodes (OLEDs) employing organic thin‐film based emitters have attracted tremendous attention due to their widespread applications in lighting and as displays in mobile devices and televisions. The novel thin‐film photovoltaic techniques using organic or organic–inorganic hybrid materials such as organic photovoltaics (OPVs) and perovskite solar cells (PSCs) have become emerging competitive candidates with regard to the traditional photovoltaic techniques on account of high‐efficiency, low‐cost, and simple manufacturing processing properties. However, OLEDs, OPVs, and PSCs are vulnerable to the undesired degradation induced by moisture and oxygen. To afford long‐term stability, a robust encapsulation technique by employing materials and structures that possess high barrier performance against oxygen and moisture must be explored and employed to protect these devices. Herein, the recent progress on specific encapsulation materials and techniques for three types of devices on the basis of fundamental understanding of device stability is reviewed. First, their degradation mechanisms, as well as, influencing factors are discussed. Then, the encapsulation technologies and materials are classified and discussed. Moreover, the advantages and disadvantages of various encapsulation technologies and materials coupled with their encapsulation applications in different devices are compared. Finally, the ongoing challenges and future perspectives of encapsulation frontier are provided.

“…The feasible package effect of rGO films on OPVs was also investigated. The lifetime of the devices with a layer of rGO coating was improved by about 20% compared with those without encapsulation over a period of 50 h. Jeon et al used GO and poly(diallyldimethylammonium chloride) (PDDA) composites to encapsulate OLEDs, and the water vapor transmittance rate could be reduced by three orders of magnitude . These results indicate that rGO and related composites are excellent barrier materials that are suitable for a wide range of encapsulation applications, including several organic electronics that are easily degraded in air.…”

Two-dimensional materials provide an ideal platform for studying the fundamental properties of atomic-level thickness systems, and are appropriate for lots of engineering applications in various fields. Although 2D materials are the thinnest membranes, they have been revealed to have high impermeability even to the smallest molecule. By the virtue of this high impermeability of the 2D materials in combination with their other unique properties, 2D materials open up a variety of applications that are impossible for conventional membranes. In this review, the latest applications based on high impermeability and selective permeation of these 2D material membranes are overviewed for different fields, including environmental control, chemical engineering, electronic devices, and biosensors. The working mechanism for each kind of application is described in detail. A summary and outlook is then provided on the challenges and new directions in this emerging research field.

Organic light emitting diodes (OLEDs) have been well known for their potential usage in the lighting and display industry. The device efficiency and lifetime have improved considerably in the last three decades. However, for commercial applications, operational lifetime still lies as one of the looming challenges. In this review paper, an in-depth description of the various factors which affect OLED lifetime, and the related solutions is attempted to be consolidated. Notably, all the known intrinsic and extrinsic degradation phenomena and failure mechanisms, which include the presence of dark spot, high heat during device operation, substrate fracture, downgrading luminance, moisture attack, oxidation, corrosion, electron induced migrations, photochemical degradation, electrochemical degradation, electric breakdown, thermomechanical failures, thermal breakdown/degradation, and presence of impurities within the materials and evaporator chamber are reviewed. Light is also shed on the materials and device structures which are developed in order to obtain along with developed materials and device structures to obtain stable devices. It is believed that the theme of this report, summarizing the knowledge of mechanisms allied with OLED degradation, would be contributory in developing better-quality OLED materials and, accordingly, longer lifespan devices.
