Thermomechanical characteristics of h-BN- and POSS-based bisphenol A polycarbonate nanocomposites

The effect of octaphenyl-substituted polyoligomeric silsesquioxane and hexagonal boron nitride on mechanical, thermal, and interfacial properties of polycarbonate (PC) has been discerned in conjunction with dissipative particle dynamics for assessing solubility parameter and energy of mixing. We have explored the utilization of in situ temperature-assisted small-angle scattering (SAXS) to glean the short-range ordered inhomogeneities and electron density distribution in PC after incorporation of POSS and h-BN. The thermomechanical attributes of PC were further evaluated via differential scanning calorimetry (DSC), temperature-modulated DSC, dynamic mechanical analysis followed by tensile testing and impact characterization in addition to micromechanical analysis.
