3D atomic force microscopy (AFM) micrographs showing the surface morphology of epoxy nanocomposites (15 and 20 wt % of SiO₂). The ESA (epoxy silica A) hybrids (left) were prepared without 3-glycidyloxypropyltrimethoxysilane (GPTMS), and the ESB (epoxy silica B) hybrids (right) were prepared with GPTMS. The peaks represent silica nanoparticles and/or agglomerates, and the SiO₂ is distributed more homogeneously and less agglomerated when GPTMS is used.
