纤维素纳米纤维气凝胶的制备方法及应用进展

Preparation and Application of Cellulose Nanofiber Aerogel

纤维素气凝胶作为继无机气凝胶和聚合物气凝胶之后的第三代气凝胶,在兼具第一、二代气凝胶共性的同时融入自身优异的特性,如绿色可再生性、生物相容性和降解性。纤维素气凝胶中的天然纳米纤维素气凝胶由于其优良的柔韧性和抗压缩性而备受研究者的青睐。本文综述了近年来纤维素纳米纤维(NFC)气凝胶的制备方法及其在隔热、储能和吸附等领域的功能化应用进展。最后,本文对NFC气凝胶的未来发展趋势进行了展望。

Cellulose aerogels are the third generation aerogels after inorganic aerogels and polymer aerogels,which combination the excellent characteristics of the first and the second generation aerogels in common with their own excellent features,such as renewable,good biocompatibility,easy degradation,excellent flexibility and compression resistance.These features make them promissing environmentally friendly materials.Among the cellulose aerogels,In this paper,recent researches on nanofibrillated cellulose(NFC)aerogels,including the preparation and applications in the fields of heat insulation,energy storage and adsorption applications are reviewed.Finally,the future development trend of NFC arogel is prospected.
