Polyvinylpyrrolidone-Bridged Prussian Blue/rGO Composite as a High-Performance Cathode for K-Ion Batteries

“…Two characteristic peaks located at around 1275 and 1425 cm –1 can be identified in both bare PVP and PB/PVP-rGO (Figure j) . Compared with bare PVP, a slight left shift of the PVP peaks in PB/PVP-rGO can be observed, which is due to the enhanced interaction between the PVP and the rGO substrate or PB. , A similar shift of the PVP peak was observed in the FTIR result (Figure k), where the stretching vibration (ν) of C–H in PVP (∼2970 cm –1 ) shifts slightly toward a higher wavenumber. − These findings confirm the enhanced interaction between PVP and rGO substrates or PB in the modified PB/PVP-rGO, which will be discussed in detail later. Furthermore, chemical formulas of bare PB, PB/GO, PB/rGO, and PB/PVP-rGO were determined by the combined methods (see details in Experimental Section, Figures S5, S6, Note S1).…”

Electrohydrodynamic direct—writing of conductor—insulator-conductor multi-layer interconnection

“…The fast and low-cost direct printing of a microstructure is one of the key research areas in the all-printed electronic industry, which has attracted considerable attention. [1,2] The inkjet printing technology has demonstrated a great potential of application in the all-printed electronic industry due to its features of high efficiency, low-cost, low waste, and noncontact process. [3,4] Compared with the traditional thin layer deposition techniques, such as photolithography, [5,6] electrochemical deposition, [7,8] and thermal evaporation, [9,10] inkjet printing has better compatibility with various materials.…”

Prussian blue/RGO with less coordinated water as superior cathode material for sodium-ion batteries

“…The small peaks at 3556 cm −1 , 3594 cm −1 and 3627 cm −1 are assigned to the coordinated water in the PB framework. 12–14 The peaks of the coordinated water in the spectrum of RGOPC3 became weak and almost disappeared compared to those in the spectrum of PB; i.e. , the amount of coordinated water in the RGOPCs was decreased to some extent during the co-heating of the GO and PB.…”
