“…The electromagnetic interference shielding effect (EMI) of graphene has also been measured and proved that the shielding effectiveness of the nanocomposite increases with the graphene loading, which is mainly attributed to the formation of conducting interconnected graphene‐based sheet networks in the insulating epoxy matrix . The target value of the EMI shielding effectiveness, needed for commercial applications, is around 20 dB, value that was obtained for a concentration of 15 wt.% of graphene as shown in Figure .…”

Over the past decades, the development of high performance lightweight polymer nanocomposites and, in particular, of epoxy nanocomposites has become one the greatest challenges in material science. The ultimate goal of epoxy nanocomposites is to extrapolate the exceptional intrinsic properties of the nanoparticles to the bulk matrix. However, in spite of the efforts, this objective is still to be attained at commercially attractive scales. Key aspects to achieve this are ultimately the full understanding of network structure, the dispersion degree of the nanoparticles, the interfacial adhesion at the phase boundaries and the control of the localization and orientation of the nanoparticles in the epoxy system. In this Personal Account, we critically discuss the state of the art and evaluate the strategies to overcome these barriers.

“…A variety of fillers such as carbon nanotubes [6,7], boron nitride [8][9][10][11], graphene nanoplatelets [12,13], silicon carbide [14][15][16] and hybrid fillers [17][18][19] have been used to enhance the thermal conductivity of polymers because of their high thermal conductivity and large aspect ratio [20][21][22][23]. Various factors affect the thermal conductivity enhancement in the filled composites, such as the interfacial thermal resistance [24][25][26][27], the size [28,29] and type [18,30,31] of fillers and the distribution of fillers [12,32,33].…”

Diglycidyl ethers of bisphenol-A (DGEBA)/methyl tetrahydrophthalic anhydride/polyethersulphone (PES) blends are prepared as matrix resins for thermally conductive composites using graphite nanoplatelets (GNPs) as the conductive component. The epoxy/PES blends form a network structure via reaction-induced phase separation (RIPS) during the curing process, and the GNPs are selectively localized in the PES phase and at the interface leading to a three-dimensional continuous filler network. With this unique structure, the thermal conductivity of the epoxy/PES/10 wt% GNPs composite is increased to 0.709 W m-1 K-1 , which is nearly 3.5 times that of the pure epoxy or a 52% increase compared to the epoxy/GNP composite without PES. In addition, it is found that the impact strength of the composite relative to the unfilled material is also improved.

Graphene oxide was reduced (RGO) by naturally abundant potato starch and incorporated in phenol formaldehyde resin (PF). The PF/RGO nanocomposites were successfully fabricated by the combination of solution processing and compression molding. Here, nanocomposites composed of 0.05 wt% to 1 wt% RGO were prepared. The incorporation of RGO into the PF matrix was significantly affecting the dynamic mechanical characteristics of the nanocomposites such as storage and loss modulus and tan δ. The degree of entanglement (N), effectiveness of filler (βf), reinforcement efficiency factor (r), cross‐link density (vc), and adhesion factor (A) were evaluated from the modulus values. Besides, the phase behavior of the nanocomposites was analyzed with help of Cole–Cole plot. The electrical properties of the nanocomposites have been studied concerning change in filler loading and frequency. The dielectric constant (ε′), dielectric loss (ε″) and conductivity were increased with increase in wt% of filler for the entire range of frequencies (20 Hz to 30 MHz) and the results showed that the electrical conductivity of the nanocomposites can be explained by percolation theory. The Maxwell‐Garnet model was employed to calculate the theoretical dielectric constant of PF/RGO nanocomposites.
