Controlling gas permeation through materials is a key technological issue in gas separation and storage, protective coatings, and packaging. Water vapor barriers are considerably important in food packaging, sealants in lightemitting diodes, and biomedical implants. One challenge for advanced water barrier materials is simultaneously achieving high light transmittance, flexibility, and good water barrier property. The primary purpose of packaging is to protect the product from the outside environment, such as the effects of gases, water(vapor), odors, micro-organisms, dust and etc. In this work, we have tried to improve of barrier properties using boric acid as crosslinking agent. The polymer coating layer was prepared to reduce the oxygen affinity and the water affinity by crosslinking between PVA matrix and boron. |
