Influence of functionalized graphene by grafted phosphorus containing flame retardant on the flammability of carbon fiber/epoxy resin (CF/ER) composite
In this paper, the graphite oxide was prepared by modified Hummers method, and 9,10-dihydro-9-oxa-phosphaphenanthrene-10-oxide (DOPO) was grafting on the graphene by acylating chlorination method to prevent aggregate and gain synergistic flame retardancy. GrapheneeDOPO was characterized by fourier transform infrared spectroscopy (FTIR), Raman spectroscopy and X-ray photoelectron spectroscopy (XPS)...

Multi-walled carbon nanotubes supported Pd composite nanoparticles hydrothermally produced from technical grade PdO precursor
Palladium (Pd) composite nanoparticles (NPs) supported on multi-walled carbon nanotubes (MWCNTs) (denoted as Pd/MWCNTs) are fabricated by a very simple process of hydrothermal reaction (HR) using the technical grade PdO as the precursor. With a HR period of 3 h, the Pd NPs with an average size of ～5.0 nm are found to be quite uniformly dispersed on the surface of MWCNTs. Th...

Octagonal prism shaped lithium iron phosphate composite particles as positive electrode materials for rechargeable lithium-ion battery
For the first time, octagonal prism shaped lithium iron phosphate (LiFePO4) composite particles supported on the multi-walled carbon nanotubes (MWNTs) (denoted as OP-LiFePO4/MWNTs) are prepared by using a boiling reflux assisted calcination method. Interestingly, spherical LiFePO4 composite particles (indexed as S-LiFePO4/C) are produced by the same procedure in the presence...

Pt-Ni bimetallic composite nanocatalysts prepared by using multi-walled carbon nanotubes as reductants for ethanol oxidation reaction
The multi-walled carbon nanotubes (MWNTs) are introduced as reductants to prepare bimetallic PtNix composite nanocatalysts via a hydrothermal reaction for the investigation of ethanol oxidation reaction (EOR). The crystal structure and elemental analysis of PtNix/MWNTs nanocatalysts are characterized by X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDS), respec...

In Vivo MRI and X-Ray Bifunctional Imaging of Polymeric Composite Supplemented with GdPO4·H2O Nanobundles for Tracing Bone Implant and Bone Regeneration
Homogeneous and monodisperse GdPO4·H2O nanobundles are successfully synthesized via a solvothermal method. Then, GdPO4·H2O are incorporated into the composite of hydroxyapatite and poly(lactic-co-glycolic acid) to obtain a biodegradable and traceable bone implant. After implanted, the GdPO4·H2O/HA/PLGA implant and the newly formed bone can be easily traced and observed throu...

(Chemical Science) A calamitic mesogenic near-infrared absorbing croconaine dye/liquid crystalline elastomer composite
In this work, we report the first example of a calamitic mesogenic near-infrared (NIR) absorbing organic dye,
made by functionalizing a thiophene–croconaine chromophore rigid core with two symmetric long flexible
alkyl chains. The liquid crystal (LC) NIR dye YHD796 exhibits a sharp and intense NIR absorption band with
a maximum absorption peak at 796 nm. Taking advantage of the improve...

[Adv. Mater. Interfaces] Highly Efficient Actuator of Graphene/Polydopamine Uniform Composite Thin Film Driven by Moisture Gradients
Bilayer materials with different swelling behavior are usually used as actuator, yet still suffer from limitations such as poor
interlayer adhesion during frequent bending, and the complex multistep fabrication process. Here, we present a new
strategy that a structure of reduced graphene oxide/polydopamine (RGO-PDA) uniform
composite thin film can serve as highly efficient actuator driven by moist...

From soft to strong elastomers: the role of additional crosslinkings in copolymer-grafted multiwalled carbon nanotube composite thermoplastic elastomers
Fabricating elastomeric materials is one of the most important branches in current nanotechnology and composite science. The macroscopic properties of the elastomers can be modified by adding fillers through changing the types and degrees of crosslinkings. In this study, copolymer-grafted multiwalled carbon nanotube composite thermoplastic elastomers (CTPEs) have been designed, in...

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...

Enhanced in vitro mineralization and in vivo osteogenesis of composite scaffolds through controlled surface grafting of L-lactic acid oligomer on nano-hydroxyapatite.
Abstract
Nanocomposite of hydroxyapatite (HA) surface grafted with L-lactic acid oligomer (LAc oligomer) (op-HA) showed improved interface compatibility, mechanical property, and biocompatibility in our previous study. In this paper, composite scaffolds of op-HA with controlled grafting different amounts of LAc oligomer (1.1, 5.2, and 9.1 wt %) were fabricated and implan...
