Effects of layer stacking sequence on temperature response of multi-layer composite materials under dynamic conditions
Individual slabs of different types are used to form composites with either 2- or 3-layer of various stacking sequences so as to examine whether stacking order has any influence on the thermal response of the composite samples under dynamic conditions. The excess temperature profile θ(x, t) of a laminated composite slab is first derived by Green’s function (GF) method so that the adiabatic surfa...

Robust ultraviolet shielding and enhanced mechanical properties of graphene oxide/sodium alginate composite films
To enhance the mechanical performance and ultraviolet shielding property, graphene oxide was incorporated as the functional nanofiller into a sodium alginate matrix to form a composite film via a solvent-casting method. The as-obtained films were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, and thermal gravimetric; their mechanical and ...

【Compos Sci Technol】Preparation, morphology, and mechanical properties of carbon nanotube anchored polymer nanofiber composite
Carbon nanotubes (CNTs) were anchored onto electrospun nanofibers under the assistance of ultrasonication. During ultrasonication, CNTs in the dispersion medium were driven to hit the nanofibers intensively and could be uniformly embedded onto nanofiber surface. The interaction between CNTs and dispersion medium played a vital role in determining CNT decoration. Good dispersion of CNTs in the disp...

A comparative study on the in vivo degradation of poly(L-lactide) based composite implants for bone fracture fixation.
Abstract Composite of nano-hydroxyapatite (n-HAP) surface grafted with poly(L-lactide) (PLLA) (g-HAP) showed improved interface compatibility and mechanical property for bone fracture fixation. In this paper, in vivo degradation of n-HAP/PLLA and g-HAP/PLLA composite implants was investigated. The mechanical properties, molecular weight, thermal properties as well as crystallin...

Assembly of an unbalanced charged polyampholyte onto Nafion to produce high-performance composite membranes
A novel SPES-NH2–GA-Nafions composite membrane with higher proton conductivity and lower methanol permeability was fabricated by covalent crosslinking layer-by-layer self-assembly of an unbalanced charged polyampholyte (SPES-NH2) and glutaraldehyde (GA) with controllable free sulfonic acid content.

Polylactide Composite Foams Containing Carbon Nanotubes and Carbon Black: Synergistic Effect of Filler on Electrical Conductivity
Carbon, 2015, 95C, 380-387
ABSTRACT:
Two kinds of
carbonaceous particles, carbon black (CB) and carbon nanotubes (CNTs) were used
as the filler to prepare biodegradable polylactide (PLA) composites for the
study of synergistic effect of fillers on the electrical conductivity. The
results reveal that the CB particles and CNTs are loosely entangled with each
other in PLA matrix, inste...

145. Combination of Magnetic and Enhanced Mechanical Properties for Copolymer-Grafted Magnetite Composite Thermoplastic Elastomers
Composite thermoplastic elastomers (CTPEs) of magnetic copolymer-grafted nanoparticles (magnetite, Fe3O4) were synthesized and characterized to generate magnetic CTPEs, which combined the magnetic property of Fe3O4 nanoparticles and the thermoplastic elasticity of the grafted amorphous polymer matrix. Fe3O4 nanoparticles served as stiff, multiple physical cross-linking points homogeneously dispe...

Natural polysaccharides promote chondrocyte adhesion and proliferation on magnetic nanoparticle/PVA composite hydrogels
This paper aims to investigate the synergistic effects of
natural polysaccharides and inorganic nanoparticles on cell adhesion and growth
on intrinsically cell non-adhesive polyvinyl alcohol (PVA) hydrogels. Previously, we have demonstrated
that Fe2O3 and hydroxyapatite (nHAP) nanoparticles are
effective in increasing osteoblast growth on PVA hydrogels. Herein, we blended
hyaluronic acid (HA) a...

Effect of Chemical Treatments on Transverse Thermal Conductivity of Unidirectional Abaca Fiber/Epoxy Composite
Present paper investigated the effect of mercerization and silane treatments on the transverse thermal
conduction properties of unidirectional abaca fiber–epoxy composite fabricated by resin transfer molding.
As indicated by FTIR, XRD and SEM, the changes in chemical composition, crystalline and lumen
structure of abaca fibers were introduced by chemical treatments. Transverse tensile test showed...

Insights into the surface property and blood compatibility of polyethersulfone/polyvinylpyrrolidone composite membranes: toward high-performance hemodialyzer
Applications of blood purificationmembranes are fuelled by diverse clinical needs, such as hemodialysis, hemodiafiltration, hemofiltration, plasmapheresis, and plasma collection. For clinical usage, the adding of polyvinylpyrrolidone (PVP) is the general protocol for the design of antifouling and antithrombotic properties integrated artificial membranes. In the present work, to insigh...
