Summary

Nanocellulose is a novel type of cellulose nanomaterials that mainly synthesized by trees, cotton, or other higher plants. Owing to the intrinsic nanofiber structure and the advantageous mechanical, thermal, and optical properties, nanocellulose has become a star nanomaterial in recent material science field. Various nanofibrillaltion, modification and assemble strategies were developed for extracting nanocellulose from renewable materials, adjusting the nanocellulose surface physical/chemistry properties, and constructing advanced functional materials/devices. The Special Issue "Nanocellulose and Nanocellulose-Derived Functional Materials" covers research in fundamental and applied science of nanocellulose research. It focuses on recent progress and research studies of nanocellulose related to nanocellulose fabrication, nanocellulose modification, nanocellulose-derived functional materials and the application of nanocellulose and nanocellulose-derived materials in various fields. The scope of interests includes but is not limited to the following topics:
● Nanocellulose fabrication
● Nanocellulose smulation and characterization
● Nanocellulose modification
● Nanocellulose-derived films/nanopapers
● Nanocellulose-derived foams/aerogels
● Application of nanocellulose-derived materials

  • Preparation of Cellulose Nanofibrils by Multi-Site Regioselective Oxidation
  • Abstract Cellulose nanofibrils (CNFs) are promising sustainable materials that can be applied to nanocomposites, as well as medical and life-sciences devices. However, methods for the preparation of these important materials are energy intensive because heating and mechanical disintegration are required to produce cellulose fibers below 100 nm in size. In this study, CNFs were prepared through the multi-site regioselective oxidation of cellulose with 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) and periodate at room temperature (20–25°C), without any mechanical-disintegration treatment. Transmission electron microscopy (TEM) revealed that the CNFs had the average widths of 14.1, 55.4, and 81.9 nm for three different treatments. Fourier-transform infrared spectroscopy revealed… More

  • Preparation of Dicarboxyl Cellulose Nanocrystals from Agricultural Wastes by Sequential Periodate-Chlorite Oxidation
  • Abstract Agricultural waste straw is the renewable resource with the highest annual yield in the world. In value-added applications of agricultural waste, dicarboxyl cellulose nanocrystals (DCCs) are prepared from rice, wheat, and corn straw by sequential periodate-chlorite oxidation. In this study, DCCs from rice, wheat, and corn straw were characterized by transmission electron microscopy (TEM), Fourier transform infrared spectrometer, X-ray diffractometer (XRD), and thermal gravimetric analysis (TGA). The carboxyl content of the DCCs was also investigated. XRD results show that the crystallinity index decreased after sequential periodate-chlorite oxidation; however, the cellulose I structure was maintained. TEM results show that rod-shaped DCCs… More

  • Rapid Microwave-Assisted Ionothermal Dissolution of Cellulose and Its Regeneration Properties
  • Abstract Introduction of the strategy of anhydrous calcium carbonate protection incorporated with the drop by drop reaction, high-purity 1-butyl-3-methylimidazolium chloride ([Bmim] Cl) was prepared at reaction temperature of 80°C for only 10 h. Cellulose samples from different biomass sources (with different degree of polymerization characteristic) could be rapidly (no more than 10 minutes) and completely dissolved in the [Bmim] Cl using a microwave-assisted ionothermal route. Homogeneous cellulosic regenerates with high degree of polymerization and thermal stability characteristics were obtained through a coagulation process in water. Furthermore, the dissolved celluloses were readily regenerated into solid products such as casting films and spinning… More
