摘要
天然纤维素是一种自然界分布广、储量大的绿色材料。以纤维素为基体,采用冷冻干燥等技术制备的纤维素气凝胶不仅具有二氧化硅气凝胶的三维结构特征,同时还具有生物相容性、生物降解性、吸附性等优异特性。本文从纤维素气凝胶不同的原料及制备工艺出发,综述了纳米纤维素气凝胶、细菌纤维素气凝胶、再生纤维素气凝胶和纤维素衍生物气凝胶的特点、制备以及在吸附分离、生物医学、电学、载体材料等方面的应用,提出了当前纤维素气凝胶面临的问题,并对纤维素气凝胶材料的应用前景进行了展望。
Natural cellulose is a green material with wide distribution and large reserves in nature.Cellulose aerogels prepared by freeze-drying technology with cellulose as matrix have not only three-dimensional structural characteristics of silica aerogels,but also excellent properties such as biocompatibility,biodegradability and adsorbing capability.From the view point of raw materials and fabrication technology,characteristics,preparation and application of nano-cellulose aerogels,bacterial cellulose aerogels,regenerated cellulose aerogels and cellulose derivative aerogels are summarized in this article.The problems faced by cellulose aerogels are put forward and the application prospect of cellulose aerogels is prospected.
