High Gas Barrier Materials with Multilayer Morphology for Packaging Applications
Multilayer films are widely used in packaging industry to fulfil different applications. It is well known that multilayer structure is essential for high gas barrier packaging using EVOH, because moisture has negative effects on EVOH’s barrier properties [1, 2]. In order to effectively use EVOH in barrier applications, usually a moisture barrier layer and a tie layer are required [3, 4]. In thi...
متن کاملHigh Gas Barrier Adhesives as Encapsulation for Flexible OLED
For the several decade years, organic light-emitting diodes (OLEDs) have been intensively studied because of their potential applicability to large-size flat panel displays, and more recently also solid-state lighting [1-4]. However, the lifetimes of the organic electronic devices are one of the most matters for the practical use of such devices, because of the ambient moisture and oxygen immed...
متن کاملGas barrier properties of bio-inspired Laponite-LC polymer hybrid films.
Bio-inspired Laponite (clay)-liquid crystal (LC) polymer composite materials with high clay fractions (>80%) and a high level of orientation of the clay platelets, i.e. with structural features similar to the ones found in natural nacre, have been shown to exhibit a promising behavior in the context of reduced oxygen transmission. Key characteristics of these bio-inspired composite materials ar...
متن کاملPolymer Nanocomposite Technology, Fundamentals of Barrier
The term “nanocomposite” is widely employed to describe an extremely broad range of materials, where one of the components has a dimension in the sub-micron scale. A better –and far more restrictive– definition would require that a true nanocomposite should be a fundamentally new material (hybrid) in which the nanometer scale component or structure gives rise to intrinsically new properties, wh...
متن کاملBarrier crossing of a semiflexible ring polymer.
Motivated by the dynamics of a membrane in response to an external force, we study the thermally activated crossing of a semiflexible ring polymer over a potential barrier. For the bistable potential of Kramers type smoothly varying over a long length scale, we calculate the crossing rate using the multidimensional Kramers' rate theory and the functional integral method. We find that, due to it...
