Abstract One of the most important physical factors related to thermal conductivity composites filled with graphene nanoplatelets (GNPs) is dimensions GNPs, that is, their lateral size and thickness. In this study, we reveal relationship between polymer realistic GNP fillers within (measured using three-dimensional (3D) non-destructive micro X-ray CT analysis) while minimizing effects parameters other than size. A larger thickness GNPs increased likelihood matrix-bonded interface being...
Abstract The drying process of graphene-polymer composites fabricated by solution-processingfor excellent dispersion is time consuming and suffers from a restacking problem.Here, we have developed an innovative method to fabricate polymer compositeswith well dispersed graphene particles in the matrix resin using solventfree powder mixing in-situ polymerization low viscosity oligomerresin. We also prepared filled with up 20 wt% grapheneparticles solvent free while maintaining high degree...
Numerous studies have been reported on thermal interface materials based synergistic hybrid effects, however, most of them contain only fragmentary experimental results and the related model has rarely proposed to explain effects exactly. Herein, conductivities composites were systematically evaluated according various filler contents ratios. It was found that fraction secondary inducing maximum effect decreased as total content increased. In addition, when higher than optimum fraction,...
A series of polyketone (PK) nanocomposite films with varying content noncovalently functionalized graphene nanoplatelet 1-aminopyrene (GNP/APy) is prepared by solution blending a solvent hexafluoro-2-propanol. GNP/APy, facile method, can effectively induce specific interaction such as hydrogen bonding between the amine functional group GNP/APy and carbonyl PK matrix. With comparison GNP GNP/Py reference materials, intensive investigation on filler–matrix achieved. In addition, dispersion...
There is growing interest in carbon fibre fabric reinforced polymer (CFRP) composites based on a thermoplastic matrix, which easy to rapidly produce, repair or recycle. To expand the applications of CFRP composites, we propose process for fabricating conductive with improved electrical and thermal conductivities using an in-situ polymerizable cyclic butylene terephthalate oligomer can induce good impregnation fibres high dispersion nanocarbon fillers. Under optimal processing conditions,...
In this study, the thermal percolation behavior for conductivity of nanocomposites according to lateral size graphene nanoplatelets (GNPs) was studied. When amount GNPs reached critical concentration, a rapid increase in and were induced by GNP network. Interestingly, as increased, higher lower threshold observed. The in-plane nanocomposite containing 30 wt.% M25 (the largest size) 8.094 W/m·K, it improved 1518.8% compared polymer matrix. These experimentally obtained results below above...
Abstract In this study, polyamide 6 (PA6)/metal (Ni)‐plated carbon fiber (MCF) long‐fiber‐reinforced thermoplastic (LFT) composites using LFT pellets were fabricated and the variation in their mechanical, thermal, electrical properties with plating thickness was examined. The of MCF significantly influences physical mechanical properties, including resistance, strength, thermal stability, composites. PA6/MCF(90), composite a moderate thickness, exhibits optimal properties. Especially, some...
Effect of the sizes and shapes diverse carbon allotropes such as black, nanotube, graphene nanoplatelet, graphite, pitch‐based fiber (PCF), expanded graphite (EG) on thermal conductivity polymer composites is investigated. Effective improvement with microsized one‐dimensional (1D) PCF EG including intercalation spacing observed due to efficient formation transfer networks little phonon scattering at interfaces by reduction interfaces.
