a dense 3D network structure [46]. The bonding between the solid phase coating and the metal wire is often chemical, which greatly im- proves the service life and heat resistance of the coating. This is also a unique advantage of the electrophoretic deposition (EPD) method [47]. Ionic liquid polymer-functionalized carbon nanotubes were prepared by the electrodeposition method by Wu et al.... With continuous development in the field of sample preparation technology, solid phase micro-extraction (SPME) has been widely used in analytical chemistry for high extraction efficiency and convenient operation. Different materials lead to different extraction results. Among existing materials, carbon-based materials are still attracting attention from scientists due to their excellent physical and chemical properties as well as their modifiable surfaces, which could enhance the adsorption... -

angle measurements of oxyfuorinated carbon fbers were carried out using the Wilhelmy balance meth- the active functional groups presented in the thermoplastic ma- trix. As a result, the interfacial bonding strength between fbers and polymer matrix is low, and good mechanical performance of composite cannot be achieved [10-13]. To improve the surface properties and surface functional groups on... In this work, the effects of maleic anhydride (MA) content on mechanical properties of chopped carbon fibers (CFs)-reinforced MA-grafted-polypropylene (MAPP) matrix composites. A direct oxyfluorination on CF surfaces was applied to increase the interfacial strength between the CFs and MAPP matrix. The mechanical properties of the CFs/MAPP composites are likely to be different in terms of MA content. Surface characteristics were observed by scanning electron microscope, Fourier transform infrared... -

a rough surface would lead to good mechanical interlocking and enhance the interfacial bonding strength between the CFs and epoxy resin. Besides enhancing mechanical interlocking between CFs and epoxy resin, electrochemical oxidation treatment introduced oxygen-containing functional groups and thereby increased the surface polarity.

In this work, we studied the effects of electrochemical oxidation treatments of carbon fibers (CFs) on interfacial adhesion between CF and epoxy resin with various current densities. The surface morphologies and properties of the CFs before and after electrochemical-oxidation-treatment were characterized using field emission scanning electron microscopy, atomic force microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and single-fiber contact angle.

CBs. These are called surface functional groups. These surface functional groups increase the chemical and physical bonding between the CBs particles and the rubber matrix [39-43]. Therefore, the addition of CBs to rubber results in the formation of composites with im- DOI: http://dx.doi.org/ DOI:10.5714/CL.2016.18.001 This is an Open Access article distributed under the terms of the Creative... Carbon blacks (CBs) have been widely used as reinforcing materials in advanced rubber composites. The mechanical properties of CB-reinforced rubber composites are mostly controlled by the extent of interfacial adhesion between the CBs and the rubber. Surface treatments are generally performed on CBs to introduce chemical functional groups on its surface. In this study, we review the effects of various surface treatment methods for CBs. In addition, the preparation and properties of CB-reinforced... -

metals can enhance the electron donor property of the carbon matrix by catalyzing nitrogen doped graphitic carbon structure during the pyrolysis step [19]. This structure weakens the O-O bond via bonding between oxygen and nitrogen and/or the adjacent carbon atoms and facilitate the oxygen reduction reaction [24]. Apart from the disagreement on the ORR active sites, little, especially single... Nitrogen (N)-doped ordered mesoporous carbons (OMCs) with a dual transition metal system were synthesized as non-Pt catalysts for the ORR. The highly nitrogen doped OMCs were prepared by the precursor of ionic liquid (3-methyl-1-butylpyridine dicyanamide) for N/C species and a mesoporous silica template for the physical structure. Mostly, N-doped carbons are promoted by a single transition metal to improve catalytic activity for ORR in PEMFCs. In this study, our N-doped mesoporous carbons were... -

their smooth nature and chemical inertness, CFs usually exhibit poor bonding behavior in polymer matrices [15-18]. For a given matrix, the interface between the fber and the matrix will be controlled by the surface characteristics of the CFs. Consequently, surface treatments of CFs are essential to their practical application in CFRP composites. The various surface treatment methods that may... Carbon fibers (CFs) have a unique combination of properties which allow them to be widely used as reinforcing materials in advanced polymer composites. The mechanical properties of CF-reinforced polymer composites are governed mainly by the quality of interfacial adhesion between the CFs and the polymer matrix. Surface treatments of CFs are generally carried out to introduce chemical functional groups on the fiber surfaces, which provide the ability to control the surface characteristics of CFs....
