Abstract
-BN). According to the zeta potential analysis, the silane-functionalized BN nanosheets were stable suspensions and uniformly dispersed in the polymer matrix. The tensile and flexure strength of the nanocomposites showed over 100% improvement due to the covalently bonded interface. The lamellae structure of PE in the bonded interface samples was responsible for achieving higher mechanical strength in the nanocomposites. Furthermore, the thermal conductivity of the nanocomposites was significantly affected by the type of interfacial bonding, BN wt%, and operating temperature.
