摘要:

纳米纤维素是一种高透明度、高机械强度的材料,使用不同的方法如真空过滤法、溶液浇铸法等可将其制备成膜材料。通过对纳米纤维素进行改性或添加紫外屏蔽剂可以提高膜材料的紫外屏蔽性能,实现其在光敏材料覆膜、食品包装、紫外防护等领域的应用价值。首先介绍了紫外屏蔽剂作用机制,重点综述了改性纳米纤维素、纳米纤维素/无机氧化物、纳米纤维素/木质素及其他复合紫外屏蔽膜材料的研究进展,最后总结并展望了纳米纤维素基紫外屏蔽膜材料制备及应用所面临的机遇和挑战。

Abstract:

Nanocellulose is a natural material with high transparency and high mechanical strength, which could be prepared into films-forming materials using different methods such as vacuum filtration and solution casting. Modification of nanocellulose or addition of UV blocking agent could effectively improve the UV shielding performance of film materials, achieving its application value in the fields of photosensitive material coating, food packaging, UV protection and so on. In this paper, the mechanism of UV blocking agents was firstly introduced, then the research progress of the modified nanocellulose, nanocellulose/inorganic oxide and nanocellulose/lignin and other composite UV shielding film materials was mainly reviewed. Finally, the opportunities and challenges in the preparation and application of nanocellulose-based UV shielding films were summarized and prospected.

Key words: nanocellulose, ultraviolet shielding, chemical modification, inorganic oxide, lignin, composite film
