Composite films of Polyvinyl alcohol (PVA) and hybrid materials based on salicylic acid –layered zinc hydroxide acetate (ZHA-SA) using zinc hydroxide acetate (ZHA) as host matrix were obtained by the casting method. The resulting composite films were characterized by FT-IR, X-ray diffraction, scanning electron microscopy (SEM) and atomic force microscopy (AFM) evidencing the incorporation of the layered materials in PVA matrix with relatively smooth and orderly surfaces. A significant reduction in the crystallinity of neat PVA film and a slight increase in transport coefficients of oxygen through the composite films have been observed. This behaviour has been attributed to a high compatibility and adhesion between the fillers and polymeric matrix. Evaluation of the mechanical properties, in terms of stress, revealed that a low content of fillers (1.0 wt %) were able to increase the response of PVA composites by ~63% with the addition of ZHA, and ~45% with ZHA-SA. The results demonstrated the potential application of ZHA and ZHA-derived hybrid material in the preparation of multifunctional polymer composites to be used in packaging food systems.

通过流延法获得了以醋酸锌（ZHA）为基质的聚乙烯醇（PVA）和基于水杨酸层状醋酸锌（ZHA-SA）的杂化材料复合膜。通过FT-IR，X射线衍射，扫描电子显微镜（SEM）和原子力显微镜（AFM）表征所得复合膜，证明层状材料掺入具有相对光滑和有序表面的PVA基质中。观察到纯PVA膜的结晶度显着降低，并且氧通过复合膜的传输系数略有增加。该行为归因于填料与聚合物基质之间的高相容性和粘合性。根据应力评估机械性能，揭示了低含量的填料（1.0重量％）能够通过添加ZHA将PVA复合材料的响应提高约63％，将ZHA-SA增强约45％。结果证明了ZHA和ZHA衍生的杂化材料在制备用于包装食品系统的多功能聚合物复合材料中的潜在应用。
