摘　　要：纳米纤维素主要由纤维素纳米晶体(CNC)、纤维素纳米纤维(CNF)和纤维素长丝(CF)组成,一般通过机械法、化学法和生物化学法等方法制备。本实验室可以生产各种类型的纳米纤维素(CNC、CNF和CF),并已为许多研究机构和组织提供了纳米纤维素。而且为满足对产品的不同要求,还开发了高效的纳米纤维素制备工艺。我们主要探索了纳米纤维素在制浆造纸工业中的相关应用。如将CNF用于纸巾和毛巾制品,以提高吸水率[1];采用添加CNF方法,以改善纸页的湿强度,同时纸页的压榨性能稍有降低[2-3];开发纳米纤维素基锂离子电池隔膜,以改善隔膜的机械强度和孔隙率分布[4-5];采用添加纤维素长丝的方法对再造烟草薄片的机械强度进行改善,同时降低木浆纤维的添加量,从而改善再造烟草薄片的吸食口感[6-7]。Nanocellulose,mainly containing cellulose nan-ocrystals(CNC),cellulose nanofibers(CNF)and cellulose filaments(CF),is usually prepared by mechanical,chemical,and biochemical treatment.Various types of nanocellulose(CNC,CNF and CF)can be tailored produced in our lab,which have been provided for many research institutes and organizations.The efficient preparation processes of nanocellulose are developed to meet the different requirements of the products.Nanocellulose application in related pulp and paper industry is examined.CNF can be used in tissue and towel products to improve the water absorbance[1].Wet-web strength of the sheet can be improved by adding CNF,and the web pressability was decrased[2-3].Nanocellulsoe based lithium ion battery separator was also developed with improved strength and porosity distribution[4-5].CF was used to increase the strength of the reconstituted tobacco sheets and decrease the wood fiber content,thus improving the flavor of the reconstituted tobacco sheets[6-7].
