Achieving enhanced dielectric performance of reduced graphene oxide/polymer composite by a green method with pH as a stimulus

Bioinspired modified graphene oxide/polyurethane composites with rapid self-healing performance and excellent mechanical properties

“…It can be seen that there are two main loss stages on the TGA curve of GO, which can be ascribed to the loss of absorbed water and the decomposition of labile oxygen-containing groups on the surface of GO, respectively. 62 As for HBPA, there is only a sharp decomposition stage from 200 °C to 460 °C and the residual weight was only 0.54 wt%. In the case of MGO, the weight loss of the second decomposition stage was significantly reduced compared to that of GO.…”

Polydimethylsiloxane Composite Sponge Decorated with Graphene/Carbon Nanotube via Polydopamine for Multifunctional Applications

“…45,46 Besides, the D/G peak intensity ratio can be regarded as a characteristic of the sp 2 area size of graphene sheets containing the sp 2 bond and sp 3 bond. 47 As can be seen from Figure 3c, the D/G intensity ratios of GO, CNT, GO-CNT/PDA@PDMS composite sponge, and rGO-CNT/PDA@PDMS composite sponge are 1.00, 1.16, 0.99, and 1.25, respectively. It can be found that the I D /I G ratios of the rGO-CNT/PDA@PDMS composite sponge increased compared to the GO and GO-CNT/PDA@PDMS composite sponge.…”

Hyperbranched polyamide modified graphene oxide-reinforced polyurethane nanocomposites with enhanced mechanical properties

“…Then, the main weight loss of 40 wt% between 120 °C and 270 °C is due to the decomposition of labile oxygen-containing groups on the surface of GO. 56 As for HBPA, there is only one sharp decomposition stage from 200 °C to 460 °C, and the residual weight is only 0.54 wt%. In the case of HGO, the weight loss in the second decomposition stage is significantly reduced compared with that of GO.…”
