Simultaneous reduction and functionalization of graphene oxide sheets with tannic acid for a strong composite material with multi-modally interactive interfaces

Hierarchical Porous Aerogels With Multiple Adsorptive Interactions for Dye Wastewater Purification

“…This is because the functionalization of TA on the surface of GO sheets. [41] The characteristic peaks of GEL and CMCS were shown in Figure 2c. The three adsorption peaks of gelatin at 1635, 1548 and 1236 cm À 1 were assigned to the amide I, amide II and amide III band, respectively.…”

“…[39,40] Herein, based on the previous study, naturally derived tannic acid was applied to reduce GO to yield T-rGO (Figure 1). [41] A composite aerogel named CG/T-rGO was further synthesized containing GEL and CMCS double network and T-rGO sheets. In addition, EDC/NHS coupling agent was used to initiate cross-linking between GEL and CMCS chains.…”

Bio-inspired interfacial chemistry for the fabrication of a robust and functional graphene oxide composite film

“…This peak shift was due to the functionalized PEI on the surface of GO sheets, which enlarged the d -spacing between GO sheets. 32,38 Additionally, a new peak appeared at 2 θ = 17.52° corresponding to d -spacing of 5.05 Å, which originated from the reduced interlayer distance of GO sheets due to the partial deoxygenation during PEI functionalization (Fig. 2e).…”

Hydrophobic dispersion-derived Si/rGO nanocomposites in SiOC ceramic matrix as anode materials for high performance lithium-ion batteries

“…[31][32][33] Subsequently, the TA coating layer on the silicon surface can reduce GO through p-p interaction and hydrogen bonding owing to its original reducing power and affinity for GO. 34,35 That is, TA-containing Si/rGO is obtained through chemical bonding without heat treatment, and the SEM images in Fig. S1, ESI † conrm that SiNPs exist between the rGO akes.…”
