Polymeric gas barrier films play a role in pharmaceuticals, flexible electronics (organic light-emitting diode, liquid–crystal display, solar cells), and food packaging industries. The use of synthetic polymers is ubiquitous in food packaging where they provide mechanical, chemical, and microbial protection from the environment and allow product display. Polymers most frequently used in food packaging are polyethylene, polypropylene, polystyrene, polyvinyl chloride (PVC), and polyethylene terephthalate (PET). But their gas barrier properties are poor; this disadvantage limits their application in food packaging. Enhancing these poor properties would be a challenge. In this work, we have tried to improve of barrier property by using the amine materials of other structure in the silane compound modified PVA polymer matrix. The polymer coating layer was prepared to reduce the oxygen affinity and the water affinity by cross-linking between modified PVA matrix and amine materials. |
