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 کاملGas and Water Vapor Barrier Properties of Edible Films from Protein and Cellulosic Materials
Edible films were made from proteins (corn-zein and wheat gluten) and celluloses (methyl cellulose and hydroxypropyl cellulose), and tested fog permeability of gases. Oxygen and carbon dioxide permeabilities of edible films were generally lower than those of plastic films. However, water vapor permeabilities of edible films were higher than those of plastic films. The concentration of plasticiz...
متن کاملBarrier Membranes — Materials Review Part II
In part one of this two-part series on barrier membrane materials, a review of different types of barrier membranes was discussed, along with a breakdown of various features of each barrier material type and a discussion of the clinical applications best suited to each. As discussed in last month’s issue, the restoration of structure and function of bone and peridontium has been aided significa...
متن کاملGreen Barrier Materials from Cellulose Nano Fibers
In this study we prepared high grammage, robust, and structurally dense CNF (Cellulose nano fibrils) films with and without wet strength crosslinker KymeneTM (PAE, a polyamide-epichlorohydrin resin). Both selfcrosslink of PAE network and hetero crosslink between cellulose and PAE were formed at elevated temperature. Besides expected wet strength improvement, we also discovered unique stress-str...
متن کاملPhotoinduced Schottky barrier in photorefractive materials.
We report on the first experimental evidence of a Schottky barrier effect produced by the action of light in an otherwise purely Ohmic contact between a nominally undoped photorefractive titanosillenite Bi12TiO20 crystal and a transparent conductive SnO2 electrode. The photorefractive crystal is sandwiched between two transparent electrodes and a Schottky barrier is built up in the illuminated ...
