Two-phase Hybrid Thermal Interface Alkali-treated E-Glass Fiber/MWCNT/Graphene/Copper Oxide Nanocomposites for Electronic Gadgets

Introduction: Two-phase hybrid mode thermal interface materials were created and characterized for mechanical properties, thermal conductivity, and wear behaviour. Therefore, the ultimate goal of this current research was to use alkali-treated glass fibre and other allotropes to produce high-performance two-phase thermal interface materials. Method: Three different polymer composites were prepared to contain 20 vol.% alkalies NaOH treated e-glass fibre E and epoxy as a matrix with varying proportions of multi-walled carbon nanotube MWCNT, graphene G, copper oxide C. The one-phase material contained epoxy+20%e-glass+1%MWCNT EMGC1, the two-phase hybrid composite contained epoxy+20%e-glass+1%MWCNT+1%graphene+1%CuO EMGC2, and two-phase material contained epoxy+20%e-glass+1%graphene+1%CuO EMGC3. Vacuum bagging method was used for fabricating the composites. Result: The higher thermal conductivity observed was 0.3466 W/mK for EMGC2, the alkali-treated glass fibre/hybrid mode nanofillers epoxy matrix composite was mechanically tougher than the other two composites EMGC1 & EMGC3. Scanning electron microscopy analysis revealed the fine filler dispersion and homogenous interaction with the glass fibre/epoxy resin composite of the upper and lower zone, which also revealed the defective zone, fibre elongation, fibre/filler breakages, and filler leached surfaces. Conclusion: Finally, it was concluded that the hybrid mode two-phased structure EMGC2 epoxy matrix composite replicated the maximum thermal conductivity, mechanical properties, and wear properties of the other two specimens.
