Herein, we report on a transparent, water-stable, high oxygen barrier packaging film made from a combination of cellulose nanofiber (CNF) and a fluoropolymer (FP) coating. Nanofibrillation of the hardwood kraft pulp was carried out using succinic anhydride pretreatment and aqueous counter collision (ACC) technique to obtain ultrafine (5–7 nm) succinylated cellulose nanofibers (SCNF), which was readily fabricated into a thin coating (on PET film) as well as a self-standing film. Introducing the FP topcoat on SCNF enabled a synergistic enhancement of both oxygen barrier performance and stability against water-swelling.

透明的，水稳定的，基于纤维素纳米纤维的包装膜，具有低的氧渗透性。

本文中，我们报道了一种由纤维素纳米纤维（CNF）和含氟聚合物（FP）涂层组合而成的透明，水稳定，高氧阻隔性包装膜。硬木牛皮纸浆的纳米原纤化是使用琥珀酸酐预处理和水对撞（ACC）技术进行的，以获得超细（5-7 nm）的琥珀酰化纤维素纳米纤维（SCNF），该纤维很容易制成薄涂层（在PET薄膜上）以及一部独立电影。在SCNF上引入FP面漆可以协同增强氧气阻隔性能和抗水膨胀性。
