These results indicate that the chitosan/PEG blend can act as a novel and appropriate precursor to prepare low-cost NHPC materials for high-performance supercapacitors. United States Dollar(USD) To Indian Rupee(INR) Exchange Rate on () This page shows the exchange rate of United States Dollar (USD) To Indian Rupee (INR) on (). Additionally, the assembled symmetric supercapacitors show an excellent cycling stability with 94% (in 1 M H 2SO 4) and 97% (in 2 M KOH) retention after 10 000 cycles at 1 A g −1. C The single re-entered the top ten on the week ending March 3, 2018. B The single re-entered the top ten on the week ending February 10, 2018. A The single re-entered the top ten on the week ending January 6, 2018. It exhibits a high specific capacitance of 356 F g −1 in 1 M H 2SO 4 and 271 F g −1 in 2 M KOH at a current density of 1 A g −1, and over 230 F g −1 can be still retained at a high current density of 20 A g −1 in both electrolytes. 1 The duet version of 'Perfect', by Sheeran and Beyoncé, was the billing on the chart from Decemto January 13, 2018.

The sample obtained by the ratio of 3 : 2 exhibits a high specific surface area (2269 m 2 g −1), moderate nitrogen doping (3.22 at%) and optimized pore structure.

The physical and electrochemical properties of the resultant NHPC were affected by the ratio of chitosan and PEG. In this method, chitosan was used as a nitrogen-containing carbon precursor, low cost and large-scale commercial PEG was employed as a porogen. Porous structures quickly absorbed blood, leading to erythrocytes, platelets, and blood coagulation factors concentrated effectively (Liu et al., 2018), which could activate the blood coagulation system and promote the formation of blood clots (Wang, Zhang, et al., 2020). Nitrogen-doped hierarchical porous carbon (NHPC) materials were synthesized by using a chitosan/polyethylene glycol (PEG) blend as raw material through a facile carbonization–activation process.
