Summary:High-performance epoxy–SBA-15 nanocomposites were prepared by ultrasonic dual-mode mixing (UDMM) technique. The dynamic and static mechanical properties of the epoxy nanocomposites were assessed. The addition of 0.5 wt% of SBA-15 improves the storage modulus (13%) and marginally varies the glass transition temperature (~ 2%) of the respective epoxy nanocomposites. However, the failure strength (~ 77%) and strain (~ 180%) increased significantly without affecting its modulus. The FESEM images of the fracture surface of epoxy nanocomposite reveal a much rougher surface compared to neat epoxy. The addition of SBA-15 into epoxy resin restricts the movement of the cracks and deflects them to follow a meandering way and hence, creating relatively rougher surfaces. The addition of higher wt% of SBA-15 is found unable to improve the dynamic and static mechanical properties of the epoxy nanocomposites. The homogeneous dispersion of SBA-15 via UDMM results in the conversion of hydrophilic epoxy into a highly hydrophobic one. This work has the potential to open up a new avenue for SBA-15 to fabricate cost-effective epoxy nanocomposites with better thermo-mechanical and tuned wetting properties.
