Abstract

Abstract:

With the rapid development of science, technology and the economy, more and more particles in the air pose a serious threat to the atmospheric environment as well as human health. Therefore, it is crucial to utilize air filtration systems to purify the air and thus improve air quality. Cellulose is the most abundant, renewable and biodegradable polymer material in the world, and because cellulose also has the characteristics of surface modification, it has a wide range of applications in the field of filtration material preparation. In this paper, the properties and preparation methods of cellulose based air filter paper, such as pure cellulose, surface functionalized cellulose and cellulose composite materials, were briefly described. At the same time, the filtration mechanism of cellulose based air filter paper was summarized, and it was proposed that ionic liquid or metal organic framework was used to modify cellulose based air filter paper, improve the adsorption capacity of specific organic volatiles, and further oxidize and decompose under ultraviolet or visible light irradiation, so as to solve the problem of environmental pollution in a real sense.

Key words: cellulose, filter paper, modification

摘要：

随着科技与经济的飞速发展，空气中的颗粒物和气体污染物对大气环境以及人类健康带来严重的威胁，因此利用空气过滤系统对空气进行净化从而改善空气质量至关重要。纤维素是世界上含量最丰富、可再生、可生物降解的高分子材料，并且由于还具有多孔性和表面可改性的特征，因此在过滤材料制备领域有广泛的应用前景。本文简述了纯纤维素、表面功能化纤维素以及纤维素复合材料等多种纤维素基空气滤纸的性能和制备方法，并对不同种类的纤维素基空气滤纸的应用场景进行了对比与分类。同时也对纤维素基空气滤纸的过滤机理进行了归纳与总结，并提出采用离子液体或者有机金属框架对纤维素基空气滤纸改性，可提高对特定有机挥发物的吸附能力，进一步在紫外光或者可见光的照射下氧化分解，达到真正意义上解决环境污染问题。
