What factors control the mechanical properties of poly (dimethylsiloxane) reinforced with nanosheets of 3-aminopropyltriethoxysilane modified graphene oxide?

On the mechanical behavior of basalt fiber/epoxy composites filled with silanized graphene oxide nanoplatelets

“…The weak band at around 1,340 cm −1 corresponds to the stretching vibration of O–H in the basal plan of GONPs . The characteristic band at 2,900 cm −1 is assigned to C–H stretching vibration and the peaks at 1,069 and 1,165 cm −1 represent the existence of C–O bands and C–O–C stretching of epoxy groups, respectively . In fact, C=C and C–C form the honeycomb structure of graphene, while O and H atoms locate on the surface of graphene in the form of O–H, C–H, and C=O functional groups.…”

“…Coupling agents have two different functional groups in their specific structures, one side fits with polymeric matrix and other is bonded to functional groups on the surface of graphene . One of the most commonly used types of coupling agents are silane coupling agents and most of the widely used silane coupling agents are organosilanes . It has been reported that the chemical modification of graphene results in better dispersion in polymer matrix and enhances the mechanical behaviors of the final nanocomposites .…”

The improved thermal oxidative stability of silicone rubber by incorporating reduced graphene oxide: Impact factors and action mechanism

“…These indicate the addition of rGO disrupted the pre‐existing little order of SR matrix. In other words, rGO dispersed homogeneously in SR matrix, and thus restricted the mobility of polymer chain . In contrast, for rGO‐1.5/SR nanocomposite, almost no decrease occurs for this amorphous diffraction peak intensity, revealing its relatively poor dispersion.…”

A novel ternary GO@SiO2‐HPW nanocomposite as an efficient heterogeneous catalyst for the synthesis of benzazoles in aqueous media

“…The TGA curves in Figure demonstrate a weight loss around 100 °C, which was related to the loss of absorbed water molecules. The weight loss of GO@SiO 2 ‐HPW below 100 °C (1.0%) was lower compared to that of GO@SiO 2 (3.0%), which indicates that the hydrophilic feature of GO@SiO 2 was reduced after modification with the hydrophobic APTES functional group . Moreover, the pronounced weight loss in the temperature range 250–600°C (10.0%) can be attributed to the degradation of APTES (Figure ).…”
