Cellulose fiber reinforced thermoplastic composites: Processing and Product Charateristics
Steam exploded fibers from Yellow Poplar (Liriodendron tulipifera) wood were assessed in terms of (a) their impact on torque during melt processing of a thermoplastic cellulose ester (plasticized CAB); (b) their fiber incorporation and dispersion characteristics in a CAB-based composite by SEM and …

Cellulose fiber-reinforced thermoplastic composites: surface and adhesion characterization
… aimed at understanding the adhesion between wood fibers and thermoplastics. Direct applications include the development of better wood fiber composites and better paper coatings. The objectives of the study were two-fold. First, to quantify the effects of surface treatments on the surface …

Cellulose fiber dissolution in sodium hydroxide solution at low temperature: dissolution kinetics and solubility improvement
Sodium hydroxide can cause cellulose to swell and can even dissolve cellulose in a narrow range of the phase diagram. It was found that for cellulose with low to moderate degree of polymerization, the maximal solubility occurs with 8~10% soda solution. In recent years, researchers found that sodium …

Wetlaid Cellulose Fiber-Thermoplastic Hybrid Composites - Effects of Lyocell and Steam Exploded Wood Fiber Blends
Fiber hybridization involves the blending of high and low performance fibers in a common matrix to yield a composite with a balance of properties that cannot be achieved by using either fiber alone. In this study, the random wetlay process was used as a compounding method to investigate the effects …

Suspension, yielding, microstructure and applications of bacterial cellulose dispersion
… work examines the unique yielding of bacterial cellulose fiber networks using a new microrheology technique developed specifically for this purpose. The fiber gels exhibit a dynamic structural rearrangement response to applied stress that is shown to be advantageous in applications like particle …

Comparison Study Between Post-Fermentation Stillage and Pre-Fermentation Mash Utilizing Acidification and Steam Explosion Techniques for Cellulose Saccharification
<p>Pre-fermentation mash fiber and post-distillation stillage fiber were examined and compared using a variety of preparatory techniques to determine the better source for cellulose fiber saccharification. Once screened, dried, and diluted to a 10% solution, mash fiber and stillage fiber were …

Increased production of aligned cellulose nanofibrils using microfluidic mixture chambers
In this thesis, the production of cellulose macroscale fibers from cellulose nanofibrils using flow focusing in microfluidic mixture chambers is examined and tested. This process accomplishes the difficult task of aligning cellulose nanofibrils and gelling them together to create macroscale …

Lyocell Fiber-Reinforced Cellulose Ester Composites - Surface and Consolidation Considerations, and Properties
… the polymer composite system consisting of cellulose acetate butyrate (CAB) and high modulus, continuous, regenerated cellulose fiber (lyocell). Of particular concern were both the interfacial adhesion between the fiber and matrix and the consolidation process in the manufacture of these …

Modification of Wood Fiber with Thermoplastics by Reactive Steam-Explosion
… (polyethylene or polypropylene), form (pellet, fiber, or powder) and melt viscosity were studied along with oxygen gas content of the steam-explosion reactor vessel. Modification of co-processed wood fiber was characterized in four studies: microscopy analysis of dispersion of PO with wood …

Mineral Surface Catalyzed Polymerization Of Estrogen And Microbial Deactivation By Fe3+-Saturated Montmorillonite: A Potentially Low Cost Material For Water Decontamination
… montmorillonite was evenly dispersed over cellulose fiber surface. When filtering 50 mL and 200 mL water spiked with live Escherichia coli (E. coli) cells at 3.67×108 CFU/mL, Fe3+ -saturated montmorillonite impregnated paper with 50% mineral weight loading deactivated E. coli with 99% and …
