“…With a properly designed approach to achieve the modification of BNNSs, the electrical insulation properties of epoxy nanocomposites are not reduced by the addition of the nanofiller with high conductivity, i.e., silver nanoparticles, since these are effectively blocked on the surface of electrically insulated BN nanosheets. Similar features can also be obtained by combining multi-layer graphene and BNNSs, using silver nanoparticles as a bridging agent, obtaining an excellent thermally stable epoxy nanocomposite [ 87 ]. Finally, a multifunctional nanofiller, based on boron nitride nanosheets functionalized with ionic liquid, has been proposed as an additive which acts simultaneously as a curing agent and flame retardant for the epoxy matrix [ 88 ].…”

“…Often, the functionalization of the surface of a nanofiller is achieved by treatment with silane solutions, such as in the case of nanoclays [ 75 ], graphene [ 92 , 93 ], boron nitride [ 87 ], and SiO 2 nanoparticles [ 64 ]. The silane can also act as a coupling agent, allowing the graft of other chains/compounds on the surface of the nanofiller, synergistically improving the nanocomposite performance [ 22 , 94 ].…”

“…Contact between the particles of nanofiller is necessary to form thermal conduction pathways; in this condition, the heat flow is promoted and the thermal conductivity increases [ 5 , 16 , 86 , 87 ]. The interfacial interaction is also an important factor since, where weak interactions are developed, the connection between the nanoparticles can be lost and thermal conduction is less efficient [ 45 ].…”

This paper aims at reviewing the works published in the last five years (2016–2020) on polymer nanocomposites based on epoxy resins. The different nanofillers successfully added to epoxies to enhance some of their characteristics, in relation to the nature and the feature of each nanofiller, are illustrated. The organic–inorganic hybrid nanostructured epoxies are also introduced and their strong potential in many applications has been highlighted. The different methods and routes employed for the production of nanofilled/nanostructured epoxies are described. A discussion of the main properties and final performance, which comprise durability, of epoxy nanocomposites, depending on chemical nature, shape, and size of nanoparticles and on their distribution, is presented. It is also shown why an efficient uniform dispersion of the nanofillers in the epoxy matrix, along with strong interfacial interactions with the polymeric network, will guarantee the success of the application for which the nanocomposite is proposed. The mechanisms yielding to the improved properties in comparison to the neat polymer are illustrated. The most important applications in which these new materials can better exploit their uniqueness are finally presented, also evidencing the aspects that limit a wider diffusion.

“…Nano composites have shown better considerable characteristics and thermal properties due to their high surface area they have better interfacial interaction with matrix [19,20]. But due to high surface energy these nanoparticles are the cause of the agglomeration and aggregation which depletes the properties of polymer ller composites.…”

This paper demonstrated the effect of functionalized magnesium oxide (MgO) nanoparticles with 3-(Aminopropyl) triethoxysilane (APTES) as llers on the mechanical and thermal properties of epoxy composite. The functionalization of MgO (S-MgO) considerably improved the inteface between the MgO and epoxy resin. The mechanical properties of the composites revealed that the addition of functionalized MgO improved their tensile strength, modulus of elasticity, and ductility when compared to neat epoxy. In compare to neat epoxy, the in-plane thermal conductivity of the epoxy composite with S-MgO ller improved by 10 folds. These observations indicated that the silane functionalization on MgO contributes to the formation of a strong interfacial bond and a compact interconnected network between the ller and the epoxy matrix.

Thermal conduction for electronic equipment has grown in importance in light of the burgeoning of 5G communication. It is imperatively desired to design highly thermally conductive fillers and polymer composite films with prominent Joule heating characteristics and extensive mechanical properties. In this work, "solvothermal & in situ growth" method is carried out to prepare "Fungal tree"-like hetero-structured silver nanowires@boron nitride nanosheet (AgNWs@BNNS) thermally conductive fillers. The thermally conductive AgNWs@BNNS/ANF composite films are obtained by the method of "suction filtration self-assembly and hotpressing". When the mass fraction of AgNWs@BNNS is 50 wt%, AgNWs@BNNS/ANF composite film presents the optimal thermal conductivity coefficient of 9.44 W/(m • K) and excellent tensile strength of 136.6 MPa, good temperature-voltage response characteristics, superior electrical stability and reliability, which promise a wide application potential in 5G electronic devices.
