摘要：
Composite films, consisting of poly-(vinyl alcohol) (PVA) and Zostera flakes, were prepared via film casting and their properties were investigated using a variety of techniques. The composites exhibit better mechanical and thermal properties than pure PVA, while the optimum algal content is about 20% w/w. Although the water sorption capacity of the films is similar, the measurements of mass transport properties on composites reveal improved gas barrier behavior. This can be attributed to the resistance in flow, caused by impermeable algal particles. Based on their potential biodegradability and their low cost, it can be concluded that the produced samples may offer a very promising bio-composite material for packaging applications.
