Synergistic enhancement of thermal conductivity in composites filled with expanded graphite and multi-walled carbon nanotube fillers via melt-compounding based on polymerizable low-viscosity oligomer matrix

Nano-sized materials with large aspect ratios are found to be effective as second fillers for the formation of 3D thermally conductive networks in polymer composites. In this study, multi-walled carbon nanotube (MWCNT) was incorporated as second filler for polymer composites. A thermal analyzer was used to measure thermal conductivity of composites at room temperature. Expanded graphite and MWCNT, as fillers, effectively enhanced thermal conductivity of the composites due to its ...

Synergistic improvement of thermal conductivity in polymer composites filled with self-hybrid expanded graphite fillers

In this study, expanded graphite (EG) was crushed and the resulting composites were filled with various amounts of EG using a melt-mix method. Thermal conductivity was then analyzed to investigate the possible synergistic enhancement through self-hybridization. Thermal conductivity was measured at an ambient temperature and normal pressure. Composites filled with 10 wt% EG and wEG fillers improved thermal conductivity, compared to composites containing one type of filler at 20 wt%....

Effect of sodium dodecylbenzene sulphonate modifier and PP-g-MA on the morphology and thermal conductivity of PP/EG composites

This study analyzed the influence of expanded graphite (EG) and sodium dodecylbenzene sulfonate (SDBS) treated EG on the structure and thermal properties of polypropylene. Large surface areas of graphite were found to significantly enhance thermal conductivity and mechanical properties. Thermal conductivity was tested using a thermal constants analyzer. The PP/MAPP/SDBS/EG composites showed better thermal conductivity compared to PP/EG composites....

Preparation of polyvinylidene fluoride/expanded graphite composites with enhanced thermal conductivity via ball milling treatment

This article investigates the effects of improving thermal conductivity of polyvinylidene fluoride (PVDF) /expanded graphite (EG) composites using the ball milling method. PVDF is widely used in the field of thermal conductivity due to its superior mechanical properties, chemical resistance, and oxidative stability. Thermal conductivity of the composites was measured, using the transient plane source method. Results showed thermal and electrical conductivities of PVDF/GNSs composites improved due to larger ...

Preparation and thermal property analysis of Wood’s alloy/expanded graphite composite as highly conductive form-stable phase change material for electronic thermal management

Using phase change materials (PCMs) for passive cooling is an effective thermal management technique as they absorb and release large amount of latent heat. However, PCMs have low thermal conductivity and liquid leakage often occurs after the solid-liquid phase transitions. In this study, a Wood’s alloy/expanded graphite composite PCM was developed to achieve desirable thermal performance. The thermal conductivities of the composite samples were measured, based on a ...
