摘要:

現(xiàn)代工業(yè)的快速發(fā)展，石油基聚合物過(guò)度消耗引發(fā)了非再生資源短缺和環(huán)境污染雙重危機(jī)，同時(shí)也激發(fā)人類利用天然高分子材料創(chuàng)造綠色新材料。纖維素作為地球上當(dāng)今自然界中儲(chǔ)量最大天然高分子原材料，由于其極強(qiáng)的可再生性，廣泛的應(yīng)用，低廉的成本，良好的生物相容性和易降解性備受關(guān)注。與此同時(shí)，纖維素氣凝膠作為繼無(wú)機(jī)氣凝膠及雜化聚合物氣凝膠之后逐漸興起的第三代氣凝膠材料，在兼具傳統(tǒng)氣凝膠高比表面積、高孔隙率、低密度性質(zhì)基礎(chǔ)上融入纖維素材料可重復(fù)再生、易降解、相容性好等特性，同時(shí)還具備了良好的機(jī)械性能和延展性，在隔熱、吸附、催化、電磁、生物醫(yī)藥等領(lǐng)域具有廣泛的應(yīng)用前景，成為了新材料研究的熱點(diǎn)之一。本文從纖維素的溶解及纖維素基氣凝膠材料的制備與改性入手，介紹了纖維素基氣凝膠的性能提升及功能性開(kāi)發(fā)最新研究結(jié)果，綜述了纖維素基氣凝膠材料在不同領(lǐng)域應(yīng)用進(jìn)展，并對(duì)纖維素基氣凝膠材料的未來(lái)發(fā)展進(jìn)行展望。
 

Abstract:

With the rapid development of modern industry, the dual threats of the depletion of nonrenewable energy and environmental pollution caused by petroleum-based polymers motivate utilization of naturally occurring polymers to create new “green” materials. Cellulose, as the most abundant natural polymer on earth, has attracted attention due to its renewability, wide availability, low-cost, biocompatibility and biodegradability, etc. Meanwhile, Cellulose aerogel, as the new generation succeeding the inorganic and hybrid polymer-based aerogel, has attracted extensive interest from both academia and industry attribute to the combination of the advantages of highly porous materials and the the characteristics of natural- polymer materials. It possesses a high surface area, high porosity and extremely low density as same as previous aerogel, but also shows some unique properties such as renewability, easy degradability and biocompatibility, good mechanical properties and ductility, which give it potential value in the field of heat insulation, adsorption, catalysis, electricity and magnetism, biomaterial and pharmaceutical, etc. This review aims to describe new research progress of cellulose aerogel on the performance and functionality, and summarize the recent development of cellulose-based aerogel in various regions based on dissolving cellulose, preparation and modification.
