“…Metals such as copper, nickel, and stainless steel are considered the most effective EMI shielding materials [ 10 , 11 , 12 ]; however, their application is limited owing to high density and corrosion problems [ 13 , 14 , 15 , 16 , 17 ]. In recent years, research has been carried out on lightweight and anticorrosive polymer-based composites, wherein metal-plated fibers and carbon fillers are embedded in a polymer matrix, which can overcome the disadvantages of metal materials.…”

In this study, carbon nanotubes (CNTs) were grown under the same conditions as those of carbon fibers and glass fibers, and a comparative analysis was performed to confirm the potential of glass fibers with grown CNTs as electromagnetic interference (EMI) shielding materials. The CNTs were grown directly on the two fiber surfaces by a chemical vapor deposition process, with the aid of Ni particles loaded on them via a Ni-P plating process followed by heat treatment. The morphology and structural characteristics of the carbon and glass fibers with grown CNTs were analyzed using scanning electron microscopy–energy dispersive X-ray spectroscopy (SEM–EDS), X-ray diffraction (XRD), and X-ray photoelectron spectrometry (XPS), and the EMI shielding efficiency (EMI SE) of the directly grown CNT/carbon and glass fiber-reinforced epoxy matrix composites was determined using a vector-network analyzer. As the plating time increased, a plating layer serving as a catalyst formed on the fiber surface, confirming the growth of numerous nanowire-shaped CNTs. The average EMI SET values of the carbon fiber-reinforced plastic (CFRP) and glass fiber-reinforced plastic (GFRP) with grown CNTs maximized at approximately 81 and 40 dB, respectively. Carbon fibers with grown CNTs exhibited a significantly higher EMI SET value than the glass fiber-based sample, but the latter showed a higher EMI SET increase rate. This indicates that low-cost, high-quality EMI-shielding materials can be developed through the growth of CNTs on the surface of glass fibers.

“…Owing to their high thermal conductivity, low electrical conductivity, and high-temperature stability, ceramics are regarded as promising materials where such properties are needed [16]. Decoration of CF with ceramic films and/or particles is one of the ways used to form a superior thermally conductive CF-based composite with an electrically buffering coating [17]. There are a variety of methods to fabricate ceramic coatings, including sintering [18,19], laser cladding [20], dip-coating [21][22][23], chemical vapor deposition (CVD) [24][25][26][27], magnetron sputtering [28,29], or a sequence of all or some of these processes.…”

The purpose of this study is to prepare boron nitride (BN)-coated carbon fibers (CF) and to investigate the properties of as-prepared fibers as well as the effect of coating on their respective polymer–matrix composites. A sequence of solution dipping and heat treatment was performed to blanket the CFs with a BN microlayer. The CFs were first dipped in a boric acid solution and then annealed in an ammonia–nitrogen mixed gas atmosphere for nitriding. The presence of BN on the CF surface was confirmed using FTIR, XPS, and SEM analyses. Polypropylene was reinforced with BN–CFs as the first filler and graphite flake as the secondary filler. The composite characterization indicates approximately 60% improvement in through-plane thermal conductivity and about 700% increase in the electrical resistivity of samples containing BN-CFs at 20 phr. An increase of two orders of magnitude in the electrical resistivity of BN–CF monofilaments was also observed.

“…Normally, high thermal conductive performance has been obtained by adding fillers due to the thermal conductive chains or networks produced by the fillers [1][2][3][4][5]. In order to improve the thermal conductivity of composites, various inorganic ceramic fillers with high thermal conductivity have been introduced into insulation composites; notable example include silicon nitride (SiN) [6][7][8], silicon carbide (SiC) [9], boron nitride (BN) [10,11], alumina oxide (Al 2 O 3 ) [12][13][14], and alumina nitride (AlN) [15][16][17]. Among the various ceramic fillers, aluminum nitride is an important ceramic material that has attracted considerable attention due to its excellent thermal conductivity (82-170 W/mK) and electrical resistance (>10 14 Ω·cm @ R.T.), as well as its high density, wide band gap, low dielectric constant, and low thermal expansion coefficient close to that of silicon [18][19][20][21][22][23][24][25][26][27][28].…”

“…In our previous report [8], SiN-coated carbon fibers were successfully manufactured by simple wet-thermal method using silane coupling agent, resulting in a hybrid filler with high Poisson's ratio and thermal conductivity. Therefore, it was deemed possible to apply this method to the production of AlN-coated carbon fibers.…”

Abstract:In this work; the effects of an aluminum nitride (AlN) ceramic coating on the thermal conductivity of carbon fiber-reinforced composites were studied. AlN were synthesized by a wet-thermal treatment (WTT) method in the presence of copper catalysts. The WTT method was carried out in a horizontal tube furnace at above 1500 • C under an ammonia (NH 3 ) gas atmosphere balanced by a nitrogen using aluminum chloride as a precursor. Copper catalysts pre-doped enhance the interfacial bonding of the AlN with the carbon fiber surfaces. They also help to introduce AlN bonds by interrupting aluminum oxide (Al 2 O 3 ) formation in combination with oxygen. Scanning electron microscopy (SEM); Transmission electron microscopy (TEM); and X-ray diffraction (XRD) were used to analyze the carbon fiber surfaces and structures at each step (copper-coating step and AlN formation step). In conclusion; we have demonstrated a synthesis route for preparing an AlN coating on the carbon fiber surfaces in the presence of a metallic catalyst.
