Summary: This study evaluates the lifetime of OLEDs using barrier films and/or thin film encapsulations. The results show that B2D encapsulation offers better barrier performance compared to B2B encapsulation. Additionally, the L50 values for G2B and G2D encapsulations are 54% and 82% of that for G2G encapsulation.

Summary: Silicon carbonitride (SiCN) films have attracted considerable interest due to their outstanding characteristics, and the composition and properties of the films can be changed by tailoring the deposition approach and synthesis conditions. This review provides a detailed overview of the deposition process of SiCN films using volatile organosilicon compounds as single-source precursors, and discusses the correlations between the chemical structure and properties of the films.

Summary: The production of traditional packaging materials has caused significant pollution, hence Edible/Biodegradable/Compostable (EBC) films may serve as sustainable alternatives. Bovine gelatin, a major protein group in EBC materials, requires knowledge and control of barrier properties for potential industrial use. However, lack of experimental standardization in existing literature hindered comparison of gelatin barrier properties, indicating a need for further research with standardized units.

Summary: The study investigated amorphous SiCN thin films deposited by remote plasma atomic layer deposition using different deposition temperatures and plasma powers. It was found that the carbon content and dielectric constant of the film can be controlled by varying these parameters, impacting the chemical composition and wet etch rate.

Summary: Starch and gelatin are natural biopolymers that can be used as alternatives for synthetic polymers in packaging films. The addition of food colors and plasticizers to gelatin films improved moisture blocking effect and mechanical properties. The developed films have the potential to be used for packaging in various industries.

Summary: Poly(butylene adipate-co-terephthalate) (PBAT) was improved in terms of oxygen and water vapor barrier properties by incorporating poly(ethylene-co-vinyl alcohol) (EVOH). The addition of 50 wt% EVOH resulted in a 77% reduction in OTR and a 40% reduction in WVTR. The compatibility between PBAT and EVOH limited the elongation at break of the blends, with a decrease observed after 20 wt% EVOH. FTIR analysis confirmed limited hydrogen bonding between PBAT and EVOH. EVOH accelerated the hydrolytic degradation of PBAT but had no effect on biodegradation in soil.

Summary: This study investigated the properties of SiCN films deposited via PECVD for dental implant coatings. The results showed that an increase in NH3 flow rate led to higher deposition rates and the formation of N-Si bonds. Films with higher nitrogen content exhibited lower refractive indices. The contact angle of SiCN films had minimal differences, while the corrosion rate was dependent on the pH of the environment. These findings contribute to a better understanding of the properties and potential applications of SiCN films for use in dental implants.

Summary: This study presents a thin film barrier with a self-wrinkling morphology, which is composed of composites of amorphous alumina and polycrystalline zinc oxide. The experimental results show that the composite structure can significantly improve the water-resistance performance, and the self-wrinkling morphology further enhances the barrier property.

Summary: Nanocelluloses are potential high gas barrier materials for biobased food packaging, with high oxygen barrier properties. A multilayer material architecture with a biobased tie layer was developed to protect nanocellulose films from water. Coated PLA(CNC) films showed the best oxygen barrier performance due to thicker layers, and the oxygen barrier properties remained constant in different relative humidity conditions.

Summary: PBAT-based nanocomposite films with ultra-high oxygen barrier were prepared by exfoliating Na-montmorillonite in a sulfonated PBAT copolyester matrix. The films showed highly oriented MMT at certain MMT volume percentage and network-like MMT morphology at higher MMT loadings. The nanocomposite film with 32 vol% MMT exhibited significantly improved oxygen barrier compared to PBAT.
