Specific Surface Area Increase during Cellulose Nanofiber Manufacturing Related to Energy Input
Softwood fibers pretreated with a monocomponent endoglucanase were used to prepare a series of cellulose nanofiber qualities using a microfluidizer and 2 to 34 MWh ton of energy input. The specific surface area was determined for the series using critical point drying and gas adsorption. Although the specific surface area reached a maximum of 430 m g at 11 MWh ton, the nanofiber yield and trans...
متن کاملStructural Characterization and Modifications of Surface-oxidized Cellulose Nanofiber
Plant cellulose has a hierarchical structure with hemicelluloses and lignin in cell walls, forming natural composites at the nanometer/micrometer levels. The smallest elements next to cellulose molecules are cellulose microfibrils ~3 nm and several microns in width and length, respectively (Fig. 1). Each cellulose microfibril consists of 30-40 fully extended cellulose chains, and forms crystall...
متن کاملTHE EFFECT OF GRINDING TIME ON THE SPECIFIC SURFACE AREA DURING INTENSIVE GRINDING OF MINERAL POWDERS
Abstract: the changes of BET surface area of a mineral substance during intensive grinding process. Validity of the proposedmodel was tested by the experiments performed using a natural chalcopyrite mineral as well as the published data. Itwas shown that the model can predict the experimental results with a very good accuracy and can be used to predictwhat may happen under the similar experimen...
متن کاملReusable photocatalytic titanium dioxide–cellulose nanofiber films
Titanium dioxide (TiO2) is a well-studied photocatalyst that is known to break down organic molecules upon ultraviolet (UV) irradiation. Cellulose nanofibers (CNFs) act as an attractive matrix material for the suspension of photocatalytic particles due to their desirable mechanical and optical properties. In this work, TiO2–CNF composite films were fabricated and evaluated for photocatalytic ac...
