纳米纤维素材料氧气与水蒸气阻隔性能的研究现状

Oxygen and Water Vapor Barrier Properties of Nanocellulose Materials: A Review

纳米纤维素主要来源于植物纤维,具有比表面积高、强度高、密度低、透明性高、热膨胀低等特点,其特有的形态结构和表面性能使得纳米纤维素材料可以形成致密的网络结构进而提供优良的阻隔性能。本综述就纯纳米纤维素膜、纳米纤维素复合材料以及纳米纤维素涂布纸基材料重点讨论了纳米纤维素材料氧气与水蒸气阻隔性能的研究现状,以探讨纳米纤维素应用于包装材料的可能性。

Nanocellulose is a plant-based environmentally friendly nanomaterials with high crystallinity,high strength and other properties,which can form a dense network structure that blocks the transmission of molecules and has the potential to be a green barrier packaging material.In this paper,the oxygen and water vapor barrier properties of nano-cellulosic materials are elaborated from three different application forms including nanocellulose films,nanocellulose composite materials and paper-based material coated with nanocellulose.
