In the last recent years, many researches have been registered about the surface modification of inorganic nanoparticles and their loading process in organic polymers thattheir reportages are seen in some review articles. [1-3]
In this investigation, silica nanoparticles are linked with Isocyanate-functionalized polyether through urethane linkages (Figure 1).
The resulting modified nanoparticles spread in-situ in a polymer matrix produced by the reaction between diglycidyl ether of bisphenol A (DGEBA, epoxy resin) and isophorone diamine (IPD) hardener.
The nanocomposites obtained with different amount of modified silica nanoparticles are verified by TGA،SEM،XRD،FT-IR and DMA techniques.
