Xylan-based films have great potential to replace petroleum-based polymers used for packaging and coatings due to their excellent biocompatibility, biodegradability, and good gas barrier properties. However, fabricating a xylan-based film with flexible, transparent, water-proof, and excellent mechanical properties is an enormous challenge. Herein, we manufactured a series of degradable films with adjustable properties via solution-casting using a water-soluble xylan derivative. This is the first report of a pure xylan-based film with high performance, requiring no additives. The tensile strength of the xylan-based film could be controlled by adjusting the aldehyde content, which varied from 105.0 to 132.6 MPa. The smallest initial water contact angle of the xylan-based films is 93.26°, indicating that these films are hydrophobic. This work shows a simple and viable route toward manufacturing xylan-based films with high tensile strength, flexibility, and transparency, which can be used for packaging materials and coatings.

构建具有柔韧性、透明性和高强度的新型木聚糖基薄膜

木聚糖基薄膜由于其优异的生物相容性、生物降解性和良好的气体阻隔性，具有替代用于包装和涂料的石油基聚合物的巨大潜力。然而，制造具有柔韧、透明、防水和优异机械性能的木聚糖基薄膜是一个巨大的挑战。在此，我们使用水溶性木聚糖衍生物通过溶液浇铸制造了一系列具有可调性能的可降解薄膜。这是第一份关于无需添加剂的高性能纯木聚糖基薄膜的报告。木聚糖基薄膜的拉伸强度可以通过调节醛含量来控制，从 105.0 到 132.6 MPa。木聚糖基薄膜的最小初始水接触角为 93.26°，表明这些薄膜是疏水的。
