“…As shown in Figure 3, the volume and surface resistance of the films decreased gradually with increased nanofiller loading. The results suggested that although the volume resistance and surface resistance of the films decreased gradually, they were within the range of accepted properties for electronic packaging and/or electrical insulation material applications [26,[43][44][45][46][47][48]. The inset of Figure 3 shows the effects of four fillers on the flexural strength of the composites compared to the pure PVA matrix.…”

“…(GNS-MWCNT)@AgNPs/PVA flexible film specimens were successfully prepared by introducing the aforementioned structure into a polyvinyl alcohol (PVA) matrix. This combination microstructure was designed to provide an even greater opportunity to enhance λ due to a significantly higher intrinsic λ (about 3000 W/mK) of GNS and MWCNT [23][24][25][26][27][28][29][30] than that of other high-thermal conductivity ceramic fillers, such as aluminium nitride (AlN) and boron nitride (BN). Moreover, AgNPs were chosen because of their high thermal conductivity of Ag (λ = 429 W/(mK)) [6,24].…”

Polymer composites with high thermal conductivity have a great potential for applications in modern electronics due to their low cost, easy process, and stable physical and chemical properties. Nevertheless, most polymer composites commonly possess unsatisfactory thermal conductivity, primarily because of the high interfacial thermal resistance between inorganic fillers. Herein, we developed a novel method through silver functionalized graphene nanosheets (GNS) and multiwalled carbon nanotube (MWCNT) composites with excellent thermal properties to meet the requirements of thermal management. The effects of composites on interfacial structure and properties of the composites were identified, and the microstructures and properties of the composites were studied as a function of the volume fraction of fillers. An ultrahigh thermal conductivity of 12.3 W/mK for polymer matrix composites was obtained, which is an approximate enhancement of 69.1 times compared to the polyvinyl alcohol (PVA) matrix. Moreover, these composites showed more competitive thermal conductivities compared to untreated fillers/PVA composites applied to the desktop central processing unit, making these composites a high-performance alternative to be used for thermal management.
