Hemicelluloses, due to their hydrophilic nature, may tend to be overlooked as a component in water-resistant product applications. However, their domains of use can be greatly expanded by chemical derivatization. Research in which hydrophobic derivatives of hemicelluloses or combinations of hemicelluloses with hydrophobic materials are used with to prepare films and composites is considered herein. Isolation methods that have been used to separate hemicellulose from biomass are also reviewed. Finally, the most useful pathways to change the hydrophilic character of hemicelluloses to hydrophobic are reviewed. In this way, the water resistance can be increased and applications of targeted water-resistant hemicellulose developed. Several applications of these materials are discussed.
由于半纤维素具有亲水性，在防水产品应用中，它们可能容易被忽视。然而，通过化学衍生化，其应用领域可以得到极大扩展。本文考虑了使用半纤维素的疏水衍生物或将半纤维素与疏水材料结合来制备薄膜和复合材料的研究。还综述了用于从生物质中分离半纤维素的分离方法。最后，综述了将半纤维素的亲水性转变为疏水性的最有效途径。通过这种方式，可以提高其防水性，并开发出目标防水半纤维素的应用。讨论了这些材料的几种应用。
