Abstract

Here we present a new method to treat cellulose with a sulfamic acid-urea-choline chloride (ternary deep eutectic solvent) system, which can realize both swelling and sulfation of cellulose. This can greatly reduce the energy consumption in the process of cellulose nanoization, and use it to successfully prepare food packaging films for eliminating odors. We hope that due its simplicity and resource-efficiency, this method will have a widespread influence on currently used (nano) cellulose modification protocols.

摘要

在此，我们提出了一种用氨基磺酸-尿素-氯化胆碱（三元低共熔溶剂）体系处理纤维素的新方法，该方法可实现纤维素的溶胀和硫酸化。这能够大幅降低纤维素纳米化过程中的能耗，并成功用于制备消除异味的食品包装薄膜。我们希望，由于其简单性和资源高效性，该方法将对当前使用的（纳米）纤维素改性方案产生广泛影响。
