Graphite oxide (GO) wasmodified using 3-aminopropyltriethoxysilane (APTES) to facilitate itsdispersion in chloroform and poly(dimethylsiloxane) (PDMS). Fourier TransformInfrared Spectroscopy of the modified GO (MGO) demonstrated that amino groups ofAPTES were chemically attached to the surface of graphene oxide platelets. PDMS/MGOnanocomposites were fabricated via a cross-linking reaction using MGO andtetraethoxysilane (TEOS) as the cross-linkers. The structural properties of thesecomposites were studied. X-ray diffraction (XRD) results indicated that the MGOplatelets were exfoliated into nanosheets and dispersed well in PDMS. Thetriethoxy groups in APTES also act as the cross-linker for hydroxyl-terminated PDMS.
