摘  要:介绍了纳米纤维素的分类及性质,纳米纤维素分为纳米纤维素晶体(NCC)、微纤化纤维素(MFC)和细菌纳米纤维素(BNC)。NCC呈棒状晶须结构,结晶度高且具有高的力学性能;MFC呈纤丝状,具有宽的尺寸范围和更大的长径比,比表面积大,成氢键能力强;BNC呈超细网络状纤维结构,化学纯度和聚合度高,保水能力强。综述了纳米纤维素在纸基增强材料、纸基抗菌材料、纸基过滤材料、纸基导电材料、纸基发光材料、纸基绝缘材料、纸基疏水材料和纸基传感器材料领域的应用现状,并对其在纸基功能材料未来发展方向进行了展望。The classification and properties of nano-cellulose were introduced. The nano-cellulose was divided into nano-cellulose crystal(NCC), microfibrillated cellulose(MFC) and bacterial nano-cellulose(BNC). NCC has a rod-like whisker structure with high crystallinity and high mechanical properties. MFC is filamentous, with wide size range and larger aspect ratio, large specific surface area and strong hydrogen bonding ability. BNC has ultrafine network structure with high degree of chemical purity and polymerization, and strong water retention ability. The application status of nano-cellulose in paper-based reinforced materials, paper-based antimicrobial materials, paper-based filter materials, paper-based conductive materials, paper-based luminescent materials, paper-based insulating materials, paper-based hydrophobic materials and paper-based sensor materials was reviewed. The future development of nano-cellulose in paper-based functional materials was also prospected.
