Cellulose nanofibers are one class of natural fibers that have resulted in structures with remarkable mechanical properties. In this study, the cellulose nanofibers are used as reinforcements in the forms of layered films in a bio-derived resin. Assessment of swelling behavior is performed together with an assessment of the tension and fracture behavior. Crack resistance behavior is compared to...

Nano cellulose has the advantages of high degree polymerization, strength, degradability, and large specific surface area. The modifier is uniformly dispersed in matrix material to form a composite system containing nano-scale materials one phase. With regard above-mentioned competitive situation performance fibers, China should first strengthen research on engineering scale-up, focusing findin...

n,n-dichloropolystyrene sulfonamide as a decontaminant was synthesized in 5 steps from styrene monomer. styrene was first polymerized. then, sulfonation reaction was performed by h2so4 (c) followed by chlorination with pocl3 obtain chlorosulfonated polystyrene. amidification reaction was then applied to get sulfonamide resin. sulfonamide resin was treated with sodium hypochloride to obtain n,n-...

Cellulose nanofibers were isolated from softwood pulp by mechanical fibrillation process and were utilized to develop biobased nanocomposites for biomedical application. Different processing techniques were attempted to develop nanocomposites for use as artificial ligament or tendon and the composites mechanical properties at room conditions as well as at simulated body condition (37 °C and 98 ...

There is a need for polymeric hydrogen/air fuel-cell membranes that can efficiently conduct protons at moderate to high temperatures for wet and dry gas feeds. The US Department of Energy (DOE), for example, set an exceedingly stringent preliminary target for membrane conductivity, 0.10 Scm 1 at 120 8C and 50% relative humidity (RH). Herein, we describe the fabrication and basic properties of o...

background: the aim of this study was to fabricate the poly caprolactone (pcl) aligned nanofiber scaffold and to evaluate the survival, adhesion, proliferation, and differentiation of rat hair follicle stem cells (hfsc) in the graft material using electrospun pcl nanofiber scaffold for tissue engineering applications. methods: the bulge region of rat whisker was isolated and cultured in dmem: n...

Single suspended carbon nanofibers on carbon micro-structures were fabricated by directed electrospinning and subsequent pyrolysis at 900 C of carbon nanotube/polyacrylonitrile (CNT/PAN) composite material. The electrical conductivity of the nanofibers was measured at different weight fractions of CNTs. It was found that the conductivity increased almost two orders of magnitude upon adding 0.5 ...
