“…From Figure 3 c, notably, the obtained porous carbons had little mass loss even at 1200 °C and this proved that upon pyrolyzing, the porous carbons possessed very great thermal stability under inert atmosphere. As for the FT-IR patterns of N/R-2.54 sample before and after pyrolyzing in Figure 3 d, the characteristic band ascribed to –SCN at about 2050 cm −1 vanished after pyrolyzing, which suggested that no NH 4 SCN salts existed throughout carbonization [ 32 , 33 ]. Figure 3 e,f show the EDS analyses.…”

The conventional sol-gel method for preparing porous carbons is tedious and high-cost to prepare porous carbons and the control over the nanoporous architecture by solvents and carbonization is restricted. A simple and novel self-sacrificial salt templating method was first presented to adjust the microporous structure of porous carbon monoliths synthesized via the solvothermal method. Apart from good monolithic appearance, the solvothermal route allowed for ambient drying because it made sure that the polymerization reaction was completed quickly and thoroughly. The intact and crack-free porous carbon monoliths were investigated by scanning electron microscopy (SEM), thermogravimetric differential scanning calorimetry (TG-DSC), Fourier transform infrared (FT-IR), energy dispersive spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) and nitrogen sorption measurements. It was proven that the self-sacrificial salts NH4SCN had been removed during pyrolyzing and so, porous carbon monoliths could be directly obtained after carbonization without the need of washing removal of salts. Most importantly, the microporous specific surface area of the resultant porous carbon monoliths was dramatically increased up to 770 m2/g and the Brunauer–Emmett–Teller (BET) specific surface area was up to 1131 m2/g. That was because the salts NH4SCN as self-sacrificial templating helped to form more around 0.6 nm, 0.72 nm and 1.1 nm micropores. The self-sacrificial salt templating is also a suitable and feasible method for controlling the nanoporous structure of other porous materials.

“…When considering the proton conducting PVA-based blend polymer membranes like starch-PVA, PVA-poly (vinylacetate), PVA-poly (acrylonitrile), PVA-poly (ethylene glycol), PVA-poly (glycerol suberate) (PGS) polyester, PVA-poly (vinylpyrrolidone), [94][95][96][97][98][99] with an ionic salt like NH 4 SCN, there were a couple reports available. In particular, the PVA: PAM polymer blend was prepared via solution casting method.…”

Ionic liquid (IL) is now being considered as a novel contender in the development of highly conducting polymer electrolytes rather than a solvent. It has a significant impact on the electrochemical performance of polymer electrolytes. This study emphasizes the significance of low viscosity IL dispersion within a polymer (PVA) matrix. The electrical, structural and photoelectrochemical properties of the IL-doped polymer electrolyte are discussed in detail. These highly conducting IL doped solid polymer electrolytes show promise towards the development of highly efficient Supercapacitors.

“…Besides, the produced bioplastic/biopolymer blends may also be able to be used in fabrication of biocompatible and biodegradable products. Moreover, the utilization of expensive synthetic bioplastics can be reduced through consumption of biopolymers this can further lower the cost of products [1,2].…”
