Systematic understandings on the preparation andcharacterization of biomass containing polymer nanocomposites

对纤维素纳米纤维的制备方法和纳米纤维与聚烯烃的复合方法进行了不断的研究和系统的组织。对于前者，(1)适当的预处理或后处理结合水相纤维素悬浮液的超高压对抗处理，(2)纤维素的化学改性，(3)纤维素种类的选择，(4)纤维素水浆浓度的选择是主要因素。对于后者，发现(1)与聚烯烃的合成条件和(2)水溶性聚合物的共存是关键因素。

The preparation method for cellulose nanofibers and thecompositing method of the nanofibers and polyolefin have been continuously studiedand systematically organized. Concerning the former,(1) proper pre-or aftertreatments combining with the ultra high-pressure counter-collision treatment in anaqueous cellulosic suspension,(2) chemical modification of cellulose),(3) selectionof cellulose species,(4) selection of the concentration of aqueous cellulose slurrywere found to work as the main factors. Concerning the latter,(1) compositingconditions with polyolefin and(2) coexistence of hydrosoluble polymers were found tobe the critical factors.
