Influence of Vinyl Trimethoxy Silane as Surface Modifier on Physical Properties of Epoxy Vinyl Ester/Nano Glass Flakes Composite

In this work, the effect of surface modification of nano glass flake (NGF) on physical properties of nanocomposites based on epoxy vinyl ester were studied. Vinyl trimethoxy silane was used as surface modifier. Fourier transformed infrared spectroscopy(FT-IR) and Energy dispersive X-ray (EDX) techniques confirmed the surface treatment of the NGFs. Also the results showed that the water absorption properties of nanocomposites by adding surface modified nano glass flakes (MNGFs) in compare with untreated NGF filled vinyl ester dramatically decreased, and the barrier properties were obviously improved.
