Laminated aluminum thin-films as low-cost opaque moisture ultra-barriers for flexible organic electronic devices

Stability of organic solar cells with PCDTBT donor polymer: An interlaboratory study

“…Here, we point to the device encapsulation as one of the key factors for the observed outdoor stability effects. Thus special care should be given to the implementation of ultra-low moisture permeation encapsulation with effective oxygen and humidity barriers, [60][61][62][63][64][65][66] as well as to the addition of stabilizing compounds that may alleviate the rapid degradation arising from the presence of reactive radical species. [67][68][69][70]…”

Toward Environmentally Robust Organic Electronics: Approaches and Applications

“…For example, the use of ultraviolet (UV) filters substantially reduces the photodegradation of organic electronic materials . However, the introduction of an encapsulation or lamination process increases fabrication costs and reduces the degree of freedom in the fabrication process . More importantly, this type of encapsulant is neither flexible nor stretchable (except polymer barriers, which exhibit poor performance).…”

Aged layered double hydroxide nanosheet–polyvinyl alcohol dispersions for enhanced gas barrier coating performance

“…However, due to difficulties in recycling and pollution, recyclable and eventually biodegradable gas barrier packaging materials that meet future requirements must be developed. For example, the flexible electronics industry requires a water vapour transmission rate 13 at the order of 10 -3 to 10 À6 g m À2 day À1 and the food industry requires an oxygen transmission rate at the order of 10 À1 cc m À2 day À1 . A well-recognised approach to improve the gas barrier properties of a polymeric film is to introduce a longer gas diffusion pathway, namely a tortuous pathway, 14,15 by aligning inorganic nanosheets.…”
