In this study, H2Ti2O5·H2O nanotubes (TNTs) prepared through hydrothermal synthesis and TiO2 used as a raw material were deposited on the surface of bamboo fibre materials through a layer-by-layer (LBL) self-assembly technique to reduce flammability. Scanning electron microscopy indicated that the TNTs were successfully loaded onto the bamboo surface, and their content was dependent on the number...
Catalysts play a key role in the production of cellulose acetate (CA). In this study, CA derived from bamboo cellulose (BC) was synthesized in a solution mixture of acetic acid and acetic anhydride that contains catalysts. The catalytic activities of three catalysts (i.e., sulfuric, methyl benzene sulfonic, and dodecyl benzene sulfonic acids) were investigated in terms of kinetics of acetylation,...
TiO2/cellulose composite aerogels were easily fabricated by the in situ synthesis of TiO2 nanoparticles in a cellulose matrix at a mild temperature (≤80 °C). The TiO2/cellulose aerogel structure and morphology were analyzed with scanning electron microscopy, transmission electron microscopy, X-ray diffraction, thermal gravimetric analysis, and nitrogen adsorption–desorption tests as well as tensile...
Plastics with good flame retardant and gas barrier properties have been widely applied in the electrical industry. On the basis of the affinity between clay and cellulose, cellulose/montmorillonite (MMT) biobased plastics were constructed via a simple hot pressing of cellulose/MMT hydrogels prepared from a mixture of the cellulose solution and MMT suspension solution. The results of Fourier transform...
Four species of delignified woodchips with about 1 % lignin content (Chlorite–Woodchips) and a series of softwood pulps with different lignin contents were prepared by sodium chlorite delignification. After mechanical defibration, some Chlorite–Woodchips were directly subjected to dissolution treatment in NaOH/urea solvent; the others were first treated with NaOH solution to remove the hemicellulose...
In this work, we developed a strategy for Ag3PO4/cellulose nanocomposite hydrogels via in situ reduction and oxidation of Ag3PO4 nanoparticles in a cellulose matrix. The results of FT-IR, X-ray diffraction and X-ray photoelectron spectroscopy proved that the Ag3PO4 nanoparticles were successfully synthesized in situ in the cellulose hydrogels. Moreover, scanning electron microscopy and transmission...
Cellulose multi-filament fibers have been spun successfully on a pilot plant scale, from a cellulose dope in 7 wt% NaOH/12 wt% urea aqueous solution pre-cooled to −12 °C. Coagulation was accomplished in a bath with 10 wt% H2SO4/12 wt% Na2SO4 and then 5 wt% H2SO4 aqueous solution. By using different finishing oil, including H2O, 4% glycerol aqueous solution, 2% polyvinyl alcohol (PVA) aqueous solution,...
The morphology and structure of the regenerated cellulose membranes prepared from its NaOH–urea aqueous solution by coagulating with 5 wt% H2SO4–10 wt% Na2SO4 aqueous solution with different temperatures and times were investigated. The pore size, water permeability and physical properties of the membranes were measured with scanning electron micrograph (SEM), wide X-ray diffraction (WXRD), Fourier...
