摘要
作为地球上含量最丰富的天然高分子,纤维素具有来源多样、环境友好和天然可再生等优点,主要应用在造纸、纺织和化工等领域。但其分子结构中数量大、密度高的氢键不利于纤维素的溶解、提取和纯化。传统的纤维素溶解方法存在成本较高、产物不稳定和环境污染等问题,研究和开发新的纤维素溶解体系显得尤为重要。本文介绍了传统的纤维素溶解体系及其应用和近年来新的研究进展,提出了纤维素溶解中亟待解决的问题和未来的发展趋势。
As the most abundant natural polymer on the earth,cellulose is mainly utilized in the fields of paper,textile and chemical industry for its varied sources,environment-friendly and renewable property.However,the large number and high density of hydrogen bonds in the molecular structure hinder the dissolution,extraction and purification of cellulose.Due to the high cost,poor stability and environmental pollution of traditional dissolution methods,it is particularly important to research and develop new cellulose dissolution systems.In this paper,the development history,dissolution mechanism,utilization and recent progress of cellulose dissolution system are introduced,and the urgent problems and trend of development are also mentioned.
