Enhanced mechanical and thermal properties of regenerated cellulose/graphene composite fibers
In this study, a wet spinning method was applied to fabricate regenerated cellulose fibers filled with low graphene loading which was systematically characterized by SEM, TEM, FTIR and XRD techniques. Subsequently, the mechanical and thermal properties of the resulting fibers were investigated. With only 0.2 wt% loading of graphene, a ～50% improvement of tensile strength and 25% enhancement of Yo...

Barium sulfate/regenerated cellulose composite fiber with X-ray radiation resistance
In this article, submicron barium sulfate particles, as the radiation-resistant component, were incorporated into regenerated cellulose spinning solution. Then a series of X-ray radiation-resistant fibers were fabricated via a primarily industrialized wet-spinning trail, and the resultant fibers were knitted into fabrics by knitting loom. The morphology and structure of the fibers were studied wit...

A dandelion-like carbon microsphere/MnO2 nanosheets composite for supercapacitors
This article reported the electrochemical performance of a novel cabon microsphere/MnO2 nanosheets (CMS/MnO2) composite prepared by a in situ self-limiting deposition method under hydrothermal condition. The results of scanning electron microscopy (SEM) and transmission electron microscopy (TEM) revealed that MnO2 nanosheets homogeneously grew onto the surface of CMS to form a loose-packed ...

Preparation of amphiphilic superparamagnetic composite particles with tumor targeted MRI contrast agent
he Pluronic F127-folic acid conjugates were prepared via esterification reaction. Then Fe3O4 NPs were wrapped with Pluronic F127-folic acid to result in the
superparamagnetic composite particles with well dispersion and
biocompatibility. The size of most superparamagnetic composite particles was
less than 200 nm and the size of Fe3O4 core was 10-20 nm from the observation of transmission elec...

Nano-composite of poly(L-lactide) and surface grafted hydroxyapatite: Mechanical properties and biocompatibility
[Abstract]: In order to improve the bonding between hydroxyapatite (HAP) particles and poly(L-lactide) (PLLA), and hence to increase mechanical properties of the PLLA/HAP composite as potential bone substitute material, the HAP nano-particles were surface-grafted with PLLA and further blended with PLLA. The structure and properties of the composites were subsequently investigated by the mec...

Anti-fogging and icing-delay properties on composite micro- and nanostructured surfaces
A composite micro-/nanostrucutred (MN) surface is designed by using
Polyvinylidenedifluoride (PVDF) polymer combining ZnO materials via heat pattern
transfer and crystal growth techniques. The surface composed of ZnO nanohairs over
PVDF micro-ratchets (i.e., ZP-MN) displays excellent anti-fogging and icing delay
properties. The water condensed droplets can be shed off easily from ZP-MN surface
at ...

The effect of graphene dispersion on the mechanical properties of graphene/epoxy composite
The effect of dispersion state of graphene on mechanical properties of graphene/epoxy composites was investigated. The graphene sheets were exfoliated from graphite oxide(GO) via thermal reduction (thermally reduced GO, RGO). Different dispersions of RGO sheets were prepared with and without ball mill mixing. It was found that the composites with highly dispersed RGO showed higher glass ...

Biodegradable nano-composite polymer scaffolds for bone tissue engineering
Although hydroxyapatite (HA) ceramics has good osteoconductivity and osteoinductivity, the brittleness and fatigue failure in the body limit their clinical applications. Recent development of biodegradable polymers, mainly polyesters such as poly(L-lactic acid ) (PLLA), poly(glycolic acid) (PGA) and their copolymers (PLGA), is an attractive approach for tissue engineering with a wide rang...
