2、應(yīng)用前景。進一步對納米纖維素的結(jié)構(gòu)進行調(diào)控,在納米尺度操控纖維素超分子聚集體,進行結(jié)構(gòu)設(shè)計并組裝出穩(wěn)定的功能性纖維素基納米材料,即可以纖維素為原料構(gòu)建具有優(yōu)異性能的生物質(zhì)材料,這也正是目前生物質(zhì)材料和纖維素科學(xué)領(lǐng)域的研究熱點。概括了目前納米纖維素的主要制備方法:機械法、化學(xué)法和生物法,并對各種制備方法的優(yōu)缺點進行了討論,同時綜述了納米纖維素的應(yīng)用狀況,指出了納米纖維素的制備及應(yīng)用方面需要解決的主要問題及今后的發(fā)展方向。關(guān)鍵詞:納米纖維素;制備;納米材料;應(yīng)用中圖分類號:TQ353文獻標(biāo)志碼:A文章編
