Effect of the epoxycyclohexyl polyhedral oligomeric silsesquioxane content on the dynamic fragility of an epoxy resin

► We studied the incorporation of epoxyciclohexyl-POSS content in the dynamic fragility of an epoxy resin. ► We compared some results obtained from DSC and DMA analyses. ► Increasing the POSS content noted changes in the values collected from DSC analysis. ► The changes in the DMA analysis were similar for all POSS samples. ► The models applied for the nanocomposites showed, partially, agreement with literature.
